1959: Carrying the achievement system, she rolled

"Am I old?" Qin Chulong asked instead of answering, which showed that he cared about this very much. Then he looked at Wen Yan with a sharp gaze.

"Who said you are old? You are as young and handsome as you were ten years ago." Wen Yan looked at Qin Chulong with sparkling eyes, not hiding the admiration in her eyes, and spoke a coaxing word as soon as she opened her mouth.

She never cared about his appearance; what she valued was his calm character and profound knowledge.

But of course she couldn't tell the truth, even though they were already an old couple.

Because she has always known that he is a person who does not care about appearance. He is worried that she will think he is old after marriage, which makes him feel anxious. This is also a manifestation of his care for her.

As his partner, after understanding this, of course I have to calm his anxiety as soon as possible.

"Ahem..." Qin Chulong coughed lightly to cover up his loss of composure. At the same time, he turned his head subconsciously, but the upturned corners of his mouth still revealed his happy mood.

Even after being married for many years and now having two children, she still likes to look at him with such admiration and love.

Every time at this time, he felt as if his whole body was bathed in warm sunshine, every pore was relaxed, and a feeling of joy arose in his heart.

"I have some idea about the engine. Classmate Du's words made everything clear for me. I really didn't expect her to grow into what she is now." Qin Chulong said with emotion.

The student who once gave him a headache has now grown into someone he looks up to, and this is what he hopes for most.

As a teacher, what I want most is for my students to surpass me, and she really did it.

If every one of his students was like Du, then their country's technology would surely undergo earth-shaking changes.

But he also knew that people should not be too greedy.

"As a student, you have truly lived up to the saying that when a man has been away for three days, he should be looked at with new eyes. Aren't you pleased that she has washed you down on the beach as the former wave?" Wen Yan asked with a smile.

She still remembered that not long after Du Yimeng came to the research institute, Lao Qin brought Du Yimeng and Wan Ping to find her and asked her to teach them her professional knowledge.

At that time, she felt that Lao Qin's requirements for students were too high, because before that, her uncle and Mr. Liu had become teachers to both of them.

She thought Wan Ping would learn faster, but who knew that the fastest learner would be Du Yimeng.

"Well, I'm very pleased!" Qin Chulong not only did not feel embarrassed at being outdone by his students, but instead showed a pleased smile on his face.

……

The next day, Du Yimeng and Wan Ping began to improve the fire control system. The previous rangefinder was still too backward, so she wanted to use laser to make a rangefinder for the artillery.

As early as 61, the Chinese Academy of Sciences developed the first laser in China.

However, at this stage, laser technology is still in its development stage, and the main focus is on developing laser varieties, improving laser performance, and exploring and applying them.

It was not until the 70s that laser technology achieved major breakthroughs and was used in military and industry.

It took only four years for China to establish the Institute of Optical Precision Instruments and Machinery and successfully develop this technology, achieving a breakthrough.

It has to be said that no matter in which field, any scientific researcher at this time is a big shot.

The laser rangefinder that Du Yi dreams of making is to calculate the distance by measuring the time it takes for the laser to travel back and forth at the measured distance.

To put it simply, the laser rangefinder emits a short beam of laser. When the laser beam hits the target, is reflected back and received by the receiving device, the rangefinder records the time it takes for the laser to travel back and forth.

Then the next thing is a math problem. The speed of light multiplied by half the round-trip time is equal to the distance between the artillery and the target.

Finally, the distance is measured and counted by the calculator and displayed on the monitor.

Artillery laser rangefinder is used to measure the distance between artillery and target. It can help artillerymen accurately adjust the firing angle and distance of artillery.

This will improve the hit rate of artillery and combat effectiveness.

As long as a tank has a rangefinder, it is equivalent to having a pair of clairvoyant eyes and a brain that can automatically calculate.

Of course, this is a metaphor, and it has distance limitations. However, given the current level of technology, it is definitely the most advanced.

As soon as the fire control system made some small progress, Du Yimeng was called away by people from other laboratories. This was when Wan Ping's ability was demonstrated.

Through their many times of tacit cooperation, Du Yimeng uses his brain and he uses his hands, and the effect is absolute.

For the next period of time, Du Yimeng was like a busy little top, going back and forth between various laboratories.

Basically, the bosses can solve some small problems on their own, and only when there are big problems that cannot be solved will she be needed to step in.

This wasted a lot of time, and after completing the whole process, half a month had passed.

……

In Changde, Yu Hongru waited patiently for a letter from the capital.

When the letter arrived, Yu Lang called back and specifically reminded him that the letter was written by Fang Bao himself and filled up a whole page of paper.

The first thing Yu Hongru did when he received the letter was not to hide and read it quietly, but to go to Secretary Wan's office.

What bad intentions could he have? He just wants to show off... Bah, of course I share happy things with my old brothers.

Alang said it all, and Fang Bao wrote a whole page of letter.

It was the size of a piece of letter paper, so even if Fang Bao didn't recognize some characters, he could still write a few dozen. To be honest, his requirements were not high at all.

You know, his eldest granddaughter is only three years old, but she can actually write dozens of words. What an amazing thing! Shouldn't he show off a little?

Walking around at night in fine clothes is not his style.

"Old Wan, my eldest granddaughter was reluctant to leave me when she left. Look, she wrote to me as soon as she arrived in Beijing. How can this child be so thoughtful?" Yu Hongru said with emotion, but his raised eyebrows told Secretary Wan that he was very proud!

"Fang Bao can even write a letter. What a smart and good boy!" Secretary Wan almost drooled with envy. If he wanted Xiao Zhi to write to him, he would have to wait for a few years.

Then he felt bitter in his heart, because he knew that it would be impossible even in a few more years.

A month or so after Xiaozhi came back, thanks to his unremitting efforts, Xiaozhi finally agreed to get close to him.

Finally, the holiday is over, and I don’t know when I will be back next time.

By the time Xiaozhi learned to write letters, the child had grown up and would have surely forgotten his grandfather in some corner.

This child will be close to whoever takes care of him. In the future, he will definitely be close to his grandfather. What does this grandfather have to do with him?

Oh, worry!
