Back to the Republic of China to be a editor

It wasn't until the heat in the audience subsided that Zhou Guangzhao returned the spotlight to Zhou Xuan, and Tang Hua also walked back to his seat.The melodious cello BGM has sounded, and the singing is about to start.

"It is said that both sides of the Great Wall are hometowns.

do you know how long the great wall is

It provokes the cold moon at the border of the desert

It is connected to the hearts of the children of China

......"

The 16th Movement was just an event that happened [-] years ago. It's really unbelievable to think about it.

16 years ago, it was the Rehe Incident that led to China's disastrous defeat. In June and July of 1935, the "Tanggu Armistice Agreement" and the "Homei Agreement", the Nanjing government presented Recha to Japan, and then Japan planned the so-called "anti-communist autonomy" of the five North China provinces. Movement" to take away part of the sovereignty of Hebei including Pingjin. "North China is so big that there is no room for a peaceful desk" refers to this matter.

The significance of the [-]th Movement is that it achieved partial success—the national government had to oppose the North China autonomy planned by Japan, and this autonomy movement was suspended.Therefore, [-] has become a youth festival second only to May Fourth in New China.

The July 14th Incident 13 years ago still caused the entire North China to fall, and the Songhu Anti-Japanese War Shanghai and Nanjing fell. [-] years ago, Wuhan was fought and central China fell.

Fourteen years ago, historian Qian Mu withdrew from Beiping to Wuhan in order to escape the flames of war, and was driven from Wuhan to Chongqing by the Japanese army.In the air-raid shelter in Chongqing, surrounded by crying refugees and the rumble of heavy bombs above his head, Qian Mu hurriedly wrote "Outline of National History".This is a minimalist history with only two volumes, and there are many mistakes and omissions and imprecise textual research. It does not look like it was written by a historian, educator, or master of Chinese studies.Qian Mu's explanation for this is: At that time, he felt that China's national destiny was elusive, and he had already made plans to subjugate the country, but he hoped that after China was completely occupied by Japan, his descendants would not forget the civilization of their ancestors. A book of Chinese history will let future generations know about China's history and civilization achievements, and inspire future generations to restore their country.

But Japan failed to destroy China.China and Japan have been fighting for 8 years, China is getting stronger and stronger, and Japan is getting weaker and weaker, and finally Japan got down first.

6 years ago, Japan surrendered.

Five years ago, the peace talks between the Kuomintang and the Communist Party broke down and the civil war began.

Two years ago, Chiang Kai-shek was driven to Taiwan and New China was established.

One year ago, the Volunteer Army entered North Korea to join the war and drove the U.S. troops back from the Sino-North Korean border to the south of the 1th parallel.

Eleven months ago, the Volunteers captured Seoul and captured Walker, commander of the Eighth Army, alive.

Six months ago, the Volunteer Army occupied Seoul again, causing the U.S. military to lose troops again.

The vicissitudes of life have changed so much, and the speed of China's changes in the past 16 years has been so fast that almost everyone can't see it.

The 52 party was over, and Tang Hua took the train to Shanghai the next day. The T52 computer and the TC[-] supercomputer have reached critical nodes.Walking with Tang Hua were Zhou Xuan, Tang Hancheng, Aunt Ye, and the nanny.This Spring Festival will be in Shanghai.

While Tang Hua's family was rattling on the train, Shtemenko, Chief of the Soviet Army's General Staff, went to Nankou for inspection.

He originally just wanted to understand how the artillery division formed by the Chinese army using Soviet-style heavy artillery works. If they don't use it well, then the Soviet General Reference Mission can teach it by the way.The first artillery division of the Volunteer Army who had been replaced with Soviet weapons just came to Nankou, and they rested and trained here.

"This is... the Field Artillery Computer?"

The Soviet-made 152mm howitzer and 122mm howitzer did not arouse the slightest interest in Shtemenko. He was only staring at the iron box in the artillery command post in a daze.

Chapter 196, From TV to Monitor

"Comrade Marshal of Artillery Mikhail Nikolaevich Chistyakov or Comrade Kazakov is requested to form a delegation to Peking consisting of the Artillery Command and the General Staff. The delegation shall also Including officials from the Ministry of Defense Industry and the Ministry of Foreign Trade. Immediately after receiving the telegram, start to form a delegation, and the sooner it arrives in Beijing, the better."

Stemenko scribbled the telegram hastily in his notebook, tore off the page and handed it to the staff.

The schedule for visiting the First Artillery Division at Nankou was not over yet, but Shtemenko felt that he couldn't wait any longer, so he asked the staff officer to send a telegram back to the embassy first, and if he sent the telegram earlier, maybe the people from Moscow would come sooner.

During his visit to the Beijing Combat Situation Center, Shtemenko was deeply impressed by the minimalist configuration of the center’s staff and the computer’s processing of text information, but it was only a deep impression.If you want to talk about the overall evaluation, Shtemenko thinks that although the center in China is fast, it is informal and a bit too joking.

Why is a military mobilization order passed from one computer to another, and it can be issued by changing two lines of words on this computer?This is an order from the chief of staff or acting chief of staff, where is the signature of the chief of staff?What about the seal of the director of logistics and training?If it is an operational order to launch a campaign, it may have to be signed by Comrade Stalin.The telegram should also have an archive, but the Chinese send the transfer order between two computers. It is said that the military transfer order has been sent. The archive of the military order is actually a printed roll of paper, and sometimes it is not necessarily printed. , this is simply too random.

Therefore, Shitemenko feels that the simplified process of the Chinese General Staff has been oversimplified.

A super-complex organization like the General Staff cannot be reformed rashly, but there is nothing to question the super-useful thing like the field artillery computer.It just calculates quickly and without error.

……

Compared with more than four months ago, there are many new changes in Shanghai.First of all, the streets are more lively, pedestrians and vehicles shuttle, and there are more colorful and earthy billboards on the streets than four months ago.

Some time ago, Tang Hua had no time to pay attention, but a big event should have happened in Tianjin: the former leader of Tianjin Special Zone, Liu Zhang, and the two leaders were sacked.These two embezzled special funds for flood control and water conservancy, disaster relief food, relief food for cadres' families, and even migrant workers who repaired the airport to supply food subsidies, totaling more than 171 billion (old currency).It is now early December, and the two should have been arrested in Hebei. The chairman personally ordered the "No. 12 case in the Republic", and the North China Bureau proposed the death penalty, which will probably be executed in February next year.

Another change is probably that the sky above Shanghai has completely stopped. When Tang Hua was in Shanghai in August, he heard one or two air defense alerts. In fact, it was just a single aircraft of the national army for intrusion and reconnaissance. By December, the national army did not even send reconnaissance planes.

After the liberation of Shanghai in May 1949, the national army and air force raided and bombed Shanghai very violently. There was a big event where a power plant was bombed and paralyzed, causing half of Shanghai to lose power.So before the outbreak of the Korean War, China invited Soviet fighter jets to station in East China, and the first batch of 5mm anti-aircraft guns assisted were also deployed around Shanghai.The tense situation lasted for a year...Penghu was liberated.After the loss of Penghu, the national army and air force could only shiver on the island. Most of the bombers, fighters and reconnaissance planes focused on the central and southern parts of Taiwan Island, always paying attention to the movements of our troops in the Penghu Islands and Penghu Bay.By December 100, the first Hongqi-1 air defense missile regiment was stationed around Shanghai, and the national army aircraft finally disappeared completely.

"The DJ-1X walkie-talkie development project has been successfully implemented, but why do you all look a little...depressed?"

At the Shanghai Institute of Communication and Electronics, Tang Hua saw that several key experts were not very interested, so he encouraged them.

"I know that after the DJ-1X came out, the Communications Department of the General Staff felt that the military equipment was only used in a small area for fear of technical leaks, so there were very few orders for the DJ-1X... But even if someone is unhappy about this, that is The Nanjing Electronics Factory was not happy because they had fewer production tasks. The Shanghai Communication Electronics Institute only took 4 months in the first half of the year to apply the frequency domain scrambling principle to the walkie-talkie, which is very efficient in research and development.”

"Minister Tang, it's not because we haven't mass-produced the DJ-1X to equip the troops," said Zhou Jiongpan, chief engineer of the Institute of Communications and Electronics, "it's because we don't know what to do next."

"That's right, Minister Tang, after freezing the design of the DJ-1X and sending it to the factory, from June this year to now, we have completed the time-domain scrambling and two-dimensional scrambling of the walkie-talkie in one go, and all of them are in The laboratory has passed the test, and as long as the volunteers need it, the plan will be taken out to the electronics factory for production. So now the Communication Electronics Institute has no research projects.”

Tang Hua: "The development time for time-domain scrambling and two-dimensional scrambling is... 1 year, and the second plan will be completed in May next year. You are too early. Old Zhou, you divided the Communication Electronics Institute into two Two project teams are almost promoting the plan in parallel. This management method is very good. In less than 5 months, the two projects have been completed successively and passed the acceptance. So you can actually take a 8-month vacation. After the vacation, you can decide what to do next. What."

After Tang Hua finished speaking with a smile, Zhou Jiongpan and the other two persons in charge shook their heads together.

"After 4 months of vacation, the whole person is uncomfortable."

"Yes, it's actually hard to do nothing."

"Well then, the task for the next stage will be issued in advance." Tang Hua said, "To put it briefly, your task is first to read, Dmitry Adeyev's "Methods of Noise Handling in Radio Reception", This is actually Adeyev’s doctoral dissertation, and the Soviet experts have translated it into Chinese for us. The next stage of your work in Shanghai is the multiplexing technology. The simplest multiplexing technology has decades of history. History has passed. This technology is used to transmit telegrams in several directions at the same time on one telegraph line... called time-division multiplexing. The Ajieyev book I let you read mentioned a new method that may work. I put It’s called code division multiplexing, and now only China has gone the farthest in digital communication, so we simply took what he started and continued.”

"Shanghai Institute is now in the reading period," Tang Hua said. "From now to the end of the Spring Festival in 52, you can just study. Some directions are to make products, some directions are to develop feasible technologies, and some directions are to develop feasible technologies. For example, CDMA code division multiplexing, you only need to do some research that focuses on basic communication technologies. It’s still the same, after the full launch, you will form several groups to work separately. Lao Zhou will arrange it.”

……

Just like the pattern in Beijing, the Shanghai Communication Electronics Institute and the Shanghai Computer Institute are also next to each other, next door to each other.

A long-term task was assigned to the Institute of Communication and Electronics, and a short-term project was assigned to the Shanghai Institute of Computer Science, and products were about to be released soon.

"Let's see what Huawei's new products look like." In front of Tang Hua, Lebedev, and Wang Shoujue from the Shanghai Institute of Computer Science, there was a large box nailed with wooden boards. The large logo of Huawei TV Factory was pasted on the wooden box.

Nailing and unpacking, this huge box that can hold a 34-inch flat right-angle large color TV in later generations is a... 14-inch monitor.

"A TV." "The casing is beautifully made." Wang Shoujue had never used a TV before, but Lebedev had seen it in Ukraine.

"Old Lie, don't call it a TV from now on," Tang Hua said, "It's a monitor."

The first computer with a display in history appeared in 1960, DEC's PDP-1 minicomputer.Prior to this, computer output/display devices experienced a primitive age of 14 years.

A row of small lights has been used for many years as a computer display device.The on/off of lights represents 0 and 1. The computer uses punched paper tape to input the program, and calculates the result——on/off of a row of small lights.Copy down the binary number represented by the small light, and the computer user has to check the calculation again—at this time, the computer may make a wrong calculation, or the input may be wrong. After all, it is not uncommon for punched tape readers to read 0 as 1, and The computer failed to self-test and found a read error.

Speaking of which, Tang Hua's T50 and T51 computers still retain the paper tape input system, but the output device uses small lights as a 7-segment screen from the beginning, and a binary-decimal conversion circuit. T51 is simply upgraded to a 16-segment segment code screen.This large circuit board cannot increase the computing speed of the computer, but it can increase the ease of use of the computer.

In fact, at the end of 1951, in countries other than China, the Soviet Union (East) and Germany, the mainstream of computer output/display equipment was still a row of small lights.

After the T51 was put on the market, feedback from users in China and the Soviet Union was collected. Everyone responded very well to the 16-segment screen that can display letters. Although the letters displayed are a bit strange, it takes a day and a half to get used to it.As for the 3-line 16-segment code screen, it can only display 3 lines of characters. Most people have no opinions, and only a few people feel that the display is too little.
