The unparalleled talent of the country started from Harbin Institute of Technology

Chapter 155, Come and participate in the aircraft development project! Lead-acid battery (please subscribe)

On the last day of the year 1979, in the Princeton University Library, Zhu Hanting saw a paper in the Duke Mathematical Journal written by Xue Xiaoling.

The English name is Xiaoling Xue, and Zhu Hanting is of course very familiar with this name.

In particular, he also saw the name of Harbin Institute of Technology, which undoubtedly confirmed his guess.

In a foreign country thousands of miles away, Zhu Hanting actually saw a mathematical paper signed by his college classmate in a professional journal, and the content of the paper was related to the four-dimensional Poincaré conjecture.

Zhu Hanting read this paper on four-dimensional manifolds over and over again. The mathematical tools used in it were cited from Wang Duoyu's paper proving the four-dimensional Poincaré conjecture.

Zhu Hanting certainly knew about this proof paper, but he only knew the name of the mathematical tools, but he didn't know the details.

Before he went abroad, Xue Xiaoling had been pestering Wang Duoyu and was the latter's most devout "believer". She often asked Wang Duoyu for advice on the paper proving the Poincare conjecture in four-dimensional space. Many students in Harbin Institute of Technology knew about this.

Therefore, there is no doubt that the paper published in the Duke Mathematical Journal was written by Xue Xiaoling.

Zhu Hanting didn't know whether he received any guidance from Wang Duoyu behind the scenes.

Half a day later, Zhu Hanting still couldn't calm down.

He had previously thought about publishing his paper in an American mathematics journal, but he never did it.

Although he had published his paper in the domestic journal "Acta Mathematica Sinica", he was still not satisfied.

After coming to the United States, his ambitions became even greater.

But he never expected that only five months later, Xue Xiaoling, who was once defeated by him and had been beaten by him in terms of final exams and qualifications for studying in the United States, had now written a paper and successfully published it in the Duke Mathematical Journal.

Zhu Hanting found it hard to accept this news!
It was unknown how long it took before Zhu Hanting borrowed the magazine, and then took it to the office to ask the foreign teacher for advice.

I learned from foreign teachers that the Duke Mathematical Journal is also a very good professional mathematics journal. Being able to publish a paper in it is very helpful for graduating from a master's or doctoral program.

In fact, if the quality of the papers is good enough, you can graduate early as long as you have two papers.

After hearing this, Zhu Hanting felt even more complicated. Then, he handed Xue Xiaoling's paper to her and asked her to help him take a look at the quality of the paper.

The result is needless to say. After reading it, the math teacher commented:

"This is a very good paper. If you can write a paper like this and one more of the same quality, you can graduate with your doctorate early."

Upon hearing this, Zhu Hanting widened his eyes and could hardly believe his ears.

Damn it, Xue Xiaoling has never had any strength, how come she suddenly became so powerful?
"why?"

The teacher was stunned for a moment, then laughed and said:
"Don't you know? The hottest research topic in Princeton University's Department of Mathematics right now is actually the Poincaré conjecture. This paper uses a mathematical tool from the Poincaré conjecture in four-dimensional space to prove a problem about four-dimensional manifolds. This result is quite impressive."

As the mathematics center of the United States, Princeton University is home to extraordinary people who can stay here to teach.

The hottest topic in the global mathematics community at present is indeed the Poincaré conjecture.

After Wang Duoyu's three proof papers were published in the Annals of Mathematics, many people in the global mathematics community were shocked, but many people were unwilling to give up and even wanted to prove through their own efforts that Wang Duoyu's papers were wrong.

This is similar to the research topic of whether the Pontryagin class is a topological invariant.

It was Wu Wenjun who first proved between 3 and 4 that the Pontryagin classes of module and module are topological invariants.

This was followed by Thom, Rochlin and Schwartz in 1957 who proved that Pontryagin classes with rational coefficients are invariant under piecewise linear homeomorphisms.

But soon after, in 1963, John Milnor found an example to prove that the Pontryagin class of Mohr's integral coefficients is not a topological invariant.

However, the final reversal came in 1965, when Sergei Novikov proved that Pontryagin classes with rational coefficients are indeed topological invariants.

Today, Wang Duoyu is indeed the prover of the Poincare conjecture and a top expert in this field.

But there are still many young people with dreams who want to become dragon slayers and overturn Wang Duoyu's argument.

Next summer, Wang Duoyu will come to the United States to give a report, so researchers around the world related to the Poincare conjecture still have half a year to prove themselves.

As a result, the topic of the Poincaré conjecture became more popular, and Princeton University, as a center of mathematics, was more sensitive to such changes.

Hot topics have both advantages and disadvantages for researchers. The advantage is that once results are produced, they can become famous very quickly and can also get more bonuses.

The disadvantages are also very obvious. For example, if a project terminator like Wang Duoyu appears, it will be a tragedy.

It means that all the results of one or two years of hard work are gone.

Everything has to start all over again.

Zhu Hanting walked out of the office in a daze. The winter sun shone on his body, but he could not feel a trace of warmth.

“Was it really wrong for me to choose to come to the United States?”

From the current perspective, Xue Xiaoling has surpassed him, so his choice to study in the United States is certainly a wrong choice.

At the event in the evening, Zhu Hanting's bitter look as he forced a smile was noticed by Jian Xianglan and others. Others might not care, but Jian Xianglan could not ignore it.

"Is classmate Zhu heartbroken?"

Jian Xianglan joked with a smile.

After coming to the United States, Jian Xianglan felt like a fish in the ocean, feeling extremely refreshed.

Her spoken English was very good, and even though she was a little uncomfortable with listening to English at first, she got used to it after a while.

Therefore, after solving the language communication problem, Jian Xianglan naturally prefers the American side.

It was so free here, and she could get great material satisfaction. Although she was not used to the hamburgers and other things here at first, there were other delicious foods besides these.

For example, Mexican food, Chinese restaurants in Chinatown, etc.

The most important thing is that there is very beautiful scenery here. After Jian Xianglan got her driver's license, she earned money and bought a second-hand car without saying a word.

Cars in the United States are very cheap, especially used cars, which are so cheap that she can't believe it.

But if you are in China, don’t even think about it.

With her monthly subsidy of 24 yuan as a college student, even if there was a policy for private car sales in the country at that time, she didn't know when she would be able to afford it. What's more, there was no such policy at all. She could only rely on her qualifications and abilities.

If you are lucky, you may be able to get a car provided by the government when you are in your forties or fifties. If you are unlucky, forget it.

However, in the United States, as long as you have money, you can buy a used car for one or two thousand dollars.

With Jian Xianglan's ability, if she wants to earn one or two thousand dollars in the United States, she definitely can't do it by washing dishes. It's impossible to make money that quickly.

After owning a car, Jian Xianglan's living radius directly expanded by hundreds of kilometers, and her happiness index jumped several levels.

People also become more cheerful.

"Don't talk nonsense. When did I get a girlfriend?"

Zhu Hanting glared at the other person unhappily, then sighed:
"Xianglan, you know what? I saw a paper in the library today. Do you know who the author is?"

Upon hearing this, Jian Xianglan said with a nonchalant smile:
"What's going on? Did Professor Wang publish a new paper?"

"No!" Zhu Hanting shook his head.
"It's Xue Xiaoling. She wrote a paper on four-dimensional manifolds. I can't understand it at all, but it's of very high quality. It was published in the Duke Mathematical Journal. I asked a professor at our school, and he said that if she could write another paper of this quality, she could graduate with a doctorate early."

After hearing this, Jian Xianglan was stunned and her thoughts suddenly went back to a few months ago.

Unlike Zhu Hanting, Jian Xianglan found it even more difficult to accept that her former defeated opponent had suddenly become her superior.

Even Jian Xianglan submitted a paper to the Duke Mathematical Journal, but it was not approved.

So the gap between them and Xue Xiaoling became apparent immediately.

And it has only been five months, and there have been such huge changes. What about three and a half years later?
That is even more unimaginable.

Seeing this, Zhu Hanting continued:
"It seems you don't believe it, just like me. You can go check out the latest issue of the Duke Mathematical Journal. It definitely has the paper and an introduction to the author. You can tell at a glance whether what I said is true or not."

"Also, I'm planning to write a letter back home to find out what's going on."

They came to the United States to study in order to become stronger.

But they never expected that the classmates who stayed in China could also make themselves stronger, or even stronger. Of course, Zhu Hanting and Jian Xianglan were defeated.

After a while, Jian Xianglan finally spoke:

"Let's not talk about this anymore. Professor Wang will come to the United States to give a report in six months. Do you have any plans?"

"No, I've read all three of his papers, but I can only understand the first page. The rest of the paper is too difficult."

"Me too. Looks like we won't be able to attend his lecture."

The two looked at each other in silence, destined to have sleepless night.

Compared to Zhu Hanting and Jian Xianglan who might suffer from insomnia, Wang Duoyu, who was far away in Ice City, slept very soundly.

Recently, after finishing the data calculations for Yu Xingxing's project, Wang Duoyu felt relaxed again.

So he took advantage of this gap to complete the compilation of his last book, "Introduction to Aircraft System Design".

After completing this part of the task, Wang Duoyu felt a lot more relaxed.

By this time, it was already January 10, 1980, and time had passed much faster than he had imagined.

On this day, Zhu Ling came from Beijing to visit him, stayed for more than a week, and then went back.

Her stomach still didn't react at all. Wang Duoyu herself was not anxious at all. Zhu Ling seemed very anxious, but in fact she was the least anxious person.

But the two old people, Fang Zhen and Lao Zhu, were already as anxious as ants on a hot pan, and had quarreled with Zhu Ling countless times.

Faced with her parents' distrust and complaints, Zhu Ling was full of grievances and for a moment she didn't know whether her persistence was right or wrong.

Not to mention how Zhu Ling dealt with her parents, Wang Duoyu was living a happy life.

After he took out the three books, "Introduction to Aircraft System Design", "Gradual Advancement of Laminar Wing Design and Application" and "Theory and Application of Spacecraft Orbit Determination", Lin Dehong finally came to Harbin Institute of Technology to find him in person a week later.

"Duoyu, did you really write all three books on your own? Aren't you a math researcher? How come you know so much about aircraft?"

Upon hearing this, Wang Duoyu pointed to his brain and said:
"The brain is still very useful. As long as you are willing to take the time to study, leader, you can do the same."

Lin Dehong rolled his eyes immediately. He had accomplished nothing. If he had studied better back then, he would not have joined the army.

"Why is the editor-in-chief's name Yu Wang? It's too ugly, not as good as Wang Duoyu."

"How about being anonymous, is that okay?"

This time it was Wang Duoyu's turn to roll his eyes.

He really put some effort into hiding himself.

As a result, Lin Dehong still complained about this and that, which was really infuriating.

"Okay, then let's call him Yu Wang." Lin Dehong smacked his lips and then asked:

"Then if I let you participate in the design of the aircraft, you should have no problem, right?"

"Of course there are problems. I'm just a beginner and definitely can't participate in the design of aircraft. You're overthinking it."

Wang Duoyu refused without thinking twice.

Not to mention that the Y-10 aircraft project of this era would be aborted due to lack of funds, and other military aircraft projects were also very difficult. The fact that he was going to the United States in half a year meant that he was destined not to be involved in secret military projects at this time.

If something uncontrollable really happens at that time, Wang Duoyu will be in tears.

The most crucial point is that Wang Duoyu wants to participate in scientific research projects, isn’t that simple?

The reason why he chose to stay in Harbin Institute of Technology was to be able to take charge of a scientific research project, so that he could have both money and people.

Unlike other projects he had participated in before, not only was there various constraints, but it was also very difficult to get the project funds.

A few days ago, the scientific research projects of Xu Jinchao and Tang Zizhou were misappropriated by Liu Deben. Wang Duoyu certainly didn't want his own project to be treated in the same way.

So even if he wants to do a scientific research project, he will do it himself.

Lin Dehong curled his lips when he heard this. He didn't even believe the punctuation marks in Wang Duoyu's words.

However, he believed that Wang Duoyu must have his own plans, so he said that if he had any subsequent ideas, he could contact him and he would definitely be able to help him resolve the problem.

In this regard, Wang Duoyu chose not to believe the other party's lies, because Lin Dehong had said the same thing before about the Type 78 improved automatic rifle project. In the end, it still had to wait for multiple reviews and approvals from relevant leaders such as Lu Yangui before it was finally implemented.

Therefore, we can only selectively believe Lin Dehong’s words.

"Alas, the army is also short of money right now. The country has invested all the funds into economic development. If it weren't for the war this year, the funds planned to be allocated to the army would be even less."

Seeing that Wang Duoyu was unmoved, Lin Dehong began to play the emotional card.

This year we did have a battle with the monkeys in the south, which took place in several phases, from February to March, and it is basically over.

But monkeys are rebellious. As October approaches, even Wang Duoyu knows that in the next ten years, the monkeys will not be obedient, but will continue to stir up trouble and commit suicide.

There are many reasons for this incident, it's not just as simple as the monkey committing suicide.

The other reason is that we are actually taking revenge on the United States in exchange.

Lin Dehong is very clear about these things, and so is Wang Duoyu.

So it’s that easy to deal with monkeys.

"You might not know this, but my unit originally planned to have approximately 50 million in funding this year, but so far, only 36 million has been allocated."

Upon hearing this, Wang Duoyu quickly raised his hand and said:

"Stop, stop, stop, boss, how can I listen to this kind of data? Can you please stop hurting me? It's too sensitive."

"Bullshit!" Lin Dehong glared and said angrily:

"It's a secret for others, but does it need to be kept secret from you as well? Let me tell you, Comrade Wang Duoyu, although you are a mathematics professor at Harbin Institute of Technology, you are also a soldier in our army. Don't forget your own identity." Upon hearing this, Wang Duoyu rolled his eyes and said:
"Have you ever seen a soldier without a salary? Have you ever seen a soldier who doesn't have to stay in the army? At most, I'm just an outsider with a certificate, not a soldier!"

"Boss, I know what you want to do, but I'm really busy right now. You should let me take a break, right?"

Lin Dehong didn't care about that. He came here in person, so how could he go back empty-handed?
Besides, he heard that Harbin Institute of Technology has made money recently.

And the person who made Harbin Institute of Technology money was none other than Wang Duoyu.

So he came to Wang Duoyu to learn from him.

"Okay, okay, I promise, let me think about it and I'll tell you when the time comes, okay?"

Wang Duoyu, who was pestered by Lin Dehong and had no choice but to say this.

Lin Dehong was immediately overjoyed:
"Okay, okay, then you take your time to think about it. It would be best if you could come up with the best solution so that our army doesn't have to worry about money anymore."

"By the way, are you still short of bullets? I'll send you twenty more magazines next time."

He knew that one of Wang Duoyu's daily ways of leisure and entertainment was to hunt wild animals, and the skins of tigers, leopards, black bears and other animals were Wang Duoyu's favorite.

He even knew that Wang Duoyu had built a very beautiful wooden house in his hometown, and the curtains were made of animal skins.

Anyway, he has already made an appointment. When he is free, he will definitely go back to Dahonggou Village with Wang Duoyu to see the wooden house.

"No need, I still have bullets here." Wang Duoyu shook his head and refused. He had not encountered any danger. Except for going into the mountains to hunt, he would hardly use bullets at other times.

The pistol he designed before was still full of bullets and had not been touched at all.

If Wang Duoyu hadn't taken it out to check from time to time, he might have forgotten the existence of this pistol.

After Lin Dehong left, Wang Duoyu returned to his normal university life.

But less than two days after Lin Dehong left, and before the director of the Department of Aerospace, Ma Sijie, received the review results on the books such as "Introduction to Aircraft System Design", Liu Deben called.

Through the almost distorted voice on the phone, Wang Duoyu could clearly feel Liu Deben's joy.

why?
Because that battery was finally developed.

At the end of October this year, the higher authorities approved the electric bicycle company project. After receiving the notice, Liu Deben immediately started the project.

Zhang Jichuan, Fan Baojiang, Xin Zhouping and others have all reduced their courses and devoted more time and energy to small projects such as improving motor technology, developing new lead-acid battery technology and control technology.

There is no need to say much about motor technology. The brushless DC motor has been developed before and is still being improved.

It turned out that that version of the motor was already in the first phase factory outside the Harbin Institute of Technology. Well, actually, they rented a factory building of a subordinate unit of Harbin Institute of Technology as the "first phase factory" and started producing the first version of the motor.

This initial version of the motor was sold nationwide after it was produced.

According to Wang Duoyu's prediction, brushless DC motors are widely used in many fields, so just by selling motors, Diao Pai Electric Bicycle Company can make a profit first.

After several months of hard work, lead-acid batteries have now mastered technologies such as self-closing valve design, special conductive membrane separators, and polymer electrolytes, allowing this type of lead-acid battery to achieve battery sealing and high efficiency, solve the internal short circuit problem, and improve battery safety. Moreover, with its anti-leakage, low internal resistance and excellent low-temperature performance, this battery will definitely become a leader in the market.

When Wang Duoyu arrived at the teaching building of the Mechanical Engineering Department, school leaders including Li Rui, Liu Deben, and Han Jue were all there.

"Professor Wang, you're here just in time. Come and take a look. Is this the battery you designed earlier?"

After Wang Duoyu exchanged a few polite words with Secretary Li and the others, Zhang Jichuan couldn't wait to pull him over to the testing machine and let Wang Duoyu check all the test data of the battery in front of him.

"Okay, then I'll take a closer look."

The various data of this lead-acid battery in the laboratory show that it performs very well indeed.

Internal short circuit problems have been solved one after another.

Because if it is the previous lead-acid battery, it is not just as simple as an internal short circuit, leakage and other problems are common.

Lead-acid batteries are widely used in the market. For example, automobiles, power-controlled machine tools, lawn mowers, flashlights, and other portable devices are basically inseparable from lead-acid batteries.

Wang Duoyu didn’t know much about lead-acid batteries, and he had never done any scientific research in this area in his previous life, but one of his tools in his hometown was an electric bicycle.

When he was in his hometown in his previous life, he often rode an electric bicycle. His favorite was the Emma bicycle, which could run more than 30 kilometers each time it was fully charged.

Well, it can’t carry passengers. If it does, the maximum range is about 20 kilometers.

There were a few times when the car stalled halfway because the battery was dead. Wang Duoyu got angry, so he specifically looked up these battery technologies.

In order to prevent similar incidents from happening again, he hopes to solve these problems thoroughly, so he will use his computing power to combine the various data such as battery loss, and then conduct tests.

In this case, he needs to find out the battery types, technologies, etc. of different electric bicycles.

Emma electric bicycles have lithium-ion batteries, nickel-metal hydride batteries and lead-acid batteries. Other brands such as Tianneng and Chaowei also use lead-acid batteries.

So he looked up the information and knew the superior performance of lead-acid batteries.

In September and October last year, he discussed this technology with Xin Zhouping and other lead-acid battery project leaders and put forward his own insights.

Lead-acid batteries are designed in this way: in the battery, a portion of the electrolyte is absorbed in the electrodes and separators, thereby increasing the negative electrode's oxygen absorption capacity, preventing electrolyte loss, and enabling the battery to be sealed.

Wang Duoyu proposed three technical concepts: self-closing valve design, special conductive membrane separator and polymer electrolyte. He only knew the general technical design, and the details were still designed by Xin Zhouping and his team.

More than half an hour later, Wang Duoyu finished reading the relevant data, but his expression was frowning and serious, which made Liu Deben and others nervous.

Li Rui's face darkened and he said:
"Professor Wang, is there something wrong?"

Wang Duoyu came back to his senses, glanced at Li Rui, and said:
"Secretary Li, there is indeed a big problem. Teacher Xin and his team have mastered several technologies, but we don't have the matching materials. This is not a good thing for electric bicycles."

"We need to solve the problem of battery impact, because our battery needs to be placed on the bicycle, and it generally has various conditions such as normal temperature and low temperature."

"In our electric bicycle design, the maximum speed we designed is actually 35 kilometers per hour. But even so, with our current material technology, if the electric bicycle is involved in an accident, if the battery material is not good enough and it does not have better impact resistance, it is very easy for the battery to leak or even spontaneously combust."

"If something like this happens, it will be a devastating blow to our e-bike sales. The government might even take the initiative to ban us from selling them."

"On the other hand, most users don't strictly follow the instructions when it comes to battery management, such as charging, so accidents are also very likely to occur."

"So we must improve battery technology and battery slot design. Taking all aspects into consideration, we must conduct a more comprehensive design before shipping."

Otherwise, this electric bicycle project is likely to be terminated early.

In particular, Wang Duoyu also hopes that this electric bicycle project can be sold to Europe and the United States, so relevant work must be done on its safety performance and other aspects.

It doesn’t mean that the product quality must be superb because it is exported, but it is the same both domestically and abroad, the quality must be up to standard.

Wang Duoyu would not treat anyone differently, otherwise, it would be a disaster once the truth was revealed.

Why are electric bicycles rarely seen in foreign countries in the original time and space history?

First, gasoline is cheap in those countries, so whenever they go out, they will choose to use a car.

Secondly, traffic jams are relatively rare in a considerable number of countries, so the advantages of electric bicycles become disadvantages abroad.

Third, most foreigners have no concept of saving money, and their second-hand cars are indeed cheap, so there is really no market for electric bicycles.

But this era is different.

The electric bicycle designed and produced by Harbin Institute of Technology Diao Pai Electric Bicycle Company has a speed of 35 and a range of about 30 kilometers.

Then, within a radius of about ten kilometers, electric bicycles can perfectly cover travel needs, and most importantly, there will be no traffic jams.

As a result, electric bicycles still have a certain market in major cities such as New York, Los Angeles, Tokyo, and London.

In addition, there is an oil crisis going on right now, and oil prices are rising rapidly. After the United States withdrew from the Bretton Woods system in 1972, the Federal Reserve began to print US dollars on a large scale.

As a result, the global dollar base currency has expanded from more than 80 billion US dollars in the early 1970s to 350 billion US dollars in 1980.

The rapid expansion of the total amount of base money has caused inflation in the United States to soar rapidly, and global inflation has also grown rapidly.

You should know that in 1972, one US dollar could be exchanged for 2.24 RMB.

But by the end of 1979, one US dollar could only be exchanged for 1.49 RMB.

While the RMB has not been flooded with money, the US dollar has been flooded with money, and its value has of course been greatly reduced.

This is simply because there is very little economic trade between the United States and us. If it were the European and American world, it would be even more obvious how fast the US dollar is depreciating.

However, no matter what, if Diao brand electric bicycles want to go abroad, they must have excellent quality, target the market accurately, and do good marketing, only then can they be sold at a good price and achieve good sales volume.

Otherwise, everything will be in vain.

After Wang Duoyu finished speaking, Li Rui, Liu Deben, Han Jue and others looked at each other.

In fact, it is a good thing that Wang Duoyu strives for perfection, but for a newly established Diao Pai electric bicycle company, is such a high requirement too picky?

Even, a bit picky.

Xin Zhouping and the others looked a little depressed. Wang Duoyu saw this and reacted. He suddenly laughed and said:

"Of course, Professor Xin, your efforts are very worthy of recognition. I was just too worried about our project. After all, it is the hope of our Harbin Institute of Technology. It cannot afford to fail, so I am so strict."

"Secretary Li, Principal Liu, I propose that we give Teacher Xin and the others a 15-yuan bonus as an encouragement. What do you think?"

Upon hearing this, Li Rui and Liu Deben did some mental calculations and immediately nodded in agreement.

There are a total of thirty-seven people in the lead-acid battery project headed by Xin Zhouping. If each person receives fifteen yuan, the total reward is five hundred and fifty-five yuan.

This amount of money is not much, but it is not too little either.

What Harbin Institute of Technology lacks now is big money, but it still has enough small amounts of money, more than 500 yuan.

You know, the total investment in the Diao Pai Electric Bicycle Company's project is 10 million RMB.

Therefore, there is no problem in taking out 555 yuan to reward Xin Zhouping and the other 37 people.

In fact, not only is there no problem, but more rewards should be given.

Secretary Li Rui suggested:

"Don't give me fifteen yuan, that's too stingy. Give each person thirty yuan. Professor Wang is also a member of this project. I heard from Professor Xin and the others that many of the technical designs of the lead-acid battery were your ideas, so you should also take the thirty yuan reward."

Li Rui rejected Wang Duoyu's reason for refusal, so he had to take the thirty yuan whether he wanted to or not.

Otherwise, how could Xin Zhouping and the others have the nerve to take it?

The reward was decided. Considering Wang Duoyu's current wealth, he really didn't care about the thirty yuan.

But no matter what, this is the result of his hard work. No matter how small the mosquito is, it is still meat. Since the leader wants to give it, then just take it.

Is it really true that there is too much money?

Everyone walked out of the laboratory and came to an office to discuss the next plan.

Liu Deben immediately looked at Wang Duoyu and said:
"Professor Wang, it was you who proposed the electric bicycle project. Now that the lead-acid battery improvements are basically complete, we can discuss subsequent technological innovations later. Do you think we should produce and sell batteries as a separate product, just like we do with motors?"

Upon hearing this, everyone in the conference room looked at Wang Duoyu curiously. The latter pondered for a moment and nodded.
"Of course, that's no problem. We can redesign and produce it based on different product categories. For example, car batteries usually have two 12V batteries. We can directly design a 24V battery to save some battery space."

"Of course, some people may not be able to adapt to it. In that case, we can also produce 12V batteries. The specific use of batteries is up to the manufacturers themselves."

"On the other hand, we can also send people to contact the relevant factories and ask them to clearly state their battery needs. We can customize the relevant batteries according to their needs. However, if it is this type of product, then a certain number of contract orders must be signed. They must purchase the amount produced. We cannot bear this part of the risk for them."

In the original time and space history, in the first few years of reform and opening up, the spring breeze blew across the land, and major enterprises blossomed and bore fruit all over the country like bamboo shoots after rain.

However, after 1984, due to the difficulties caused by the "grant-to-loan" policy, Chinese companies were basically unable to carry out research and development, and the ratio of scientific research funds to GDP suddenly dropped to below 0.6%, leading to the complete collapse of China's electronics industry.

And after that, China's largest semiconductor company, Shanghai Component Factory No. 5, had a profit of 20.7 million yuan in 1980, with an average profit of 15,000 yuan per employee.

By 1985, the output value of Shanghai Component Factory No. 5 was still as high as 67.13 million yuan, and the profit reached 12.61 million yuan. However, by 1990, the output value dropped sharply to 14.96 million yuan, and the profit was only 1.26 million yuan.

After 1992, Shanghai Component Factory No. 5, a leading semiconductor device company in China, went bankrupt.

Wang Duoyu believed that in this time and space, the Harbin Institute of Technology Diao Pai Electric Bicycle Company proposed by him would definitely not go bankrupt so quickly.

But all risks actually come from insignificant details at the beginning, such as the one he just proposed.

If the relevant executive person in charge promised this when negotiating with other companies, perhaps this would not be a big problem in the next few years. However, if difficulties are encountered due to the "grant-to-loan" conversion, and the other company goes bankrupt, affecting Diao Pai Electric Bicycle Company, this would be a big bomb.

What if, during the same period, Diao Pai Electric Bicycle Company also experiences a sharp drop in profits or even goes into debt due to other factors, then wouldn’t the company be doomed to bankruptcy?
Therefore, Wang Duoyu had to give some warnings, otherwise, in the spring breeze of reform and opening up, some people would be blindly greedy and might completely ruin the good situation.

This is definitely not the scene that Wang Duoyu wants to see.

Upon hearing this, Liu Deben nodded happily and said:
"Okay, okay, this is a great plan. Write it down quickly and take notes. Secretary Li, if this is done, our Diao Pai Electric Bicycle Company can add another product, which will significantly increase its revenue."

"Perhaps by the end of next year, the 10 million yuan investment given to us will be recouped soon after we spend it."

The Diao Pai Electric Bicycle Company project was approved at the end of October and construction began in early November. Now it is January 12th, and the second phase of the factory is still undergoing interior decoration.

The Ice City is located in the north of my country, and foundation digging is no longer possible since November.

Therefore, concrete construction projects are completed between April and October, and other times are not suitable for construction.

Now we need to use the new factory to produce lead-acid batteries and increase revenue.

There is no other way but to find other existing factories.

Fortunately, Harbin Institute of Technology has left behind quite a few such factories, so we just need to clean them up simply, purchase the production equipment from outside, and then arrange for Xin Zhouping and others to help train technical workers and debug the equipment, and then we can start production immediately.

As for recruiting technical workers, it is very simple.

why?
Because there are tens of thousands of unemployed educated youth in the entire Ice City. These educated youth may not necessarily have any skills, but at least they can read and write.

As long as you can read, then there is no problem.
