returned to his seat and continued to eat, while Huang Lao, Qin Lao and the others all came to the seat where Qin Zhenhua was, and the big guy looked at him differently, which was obvious.

Wang Xiaoyu is also down-to-earth and generous, whatever questions her superiors ask, Wang Xiaoyu answered seriously, today's project has been decided, she will definitely try her best to make this thing happen.

With a smile and confidence on her face, Wang Xiaoyu looked at her husband next to her from time to time, full of admiration and love.

As night fell, the lights came on, and the two walked on the road outside the hotel.

"That, Brother Zhenhua, what you said today is too shocking." Wang Xiaoyu said: "Now, the atmosphere in society is not very good, and the atmosphere in this system should have changed a long time ago. ”

"Cut." Qin Zhenhua tried his best to look like he didn't care in front of his wife, this little thing is nothing.

"Actually, the main reason is that I'm not used to eating foreign food." Qin Zhenhua said: "They are all Ru Mao drinking blood, eating a slightly cooked steak, where is the food culture of our big eastern country has a long history, if I settle abroad for a long time, I will starve to death." ”

(East China Zhixiong has never been abroad, and has never looked at how tall he is abroad, he is not used to eating foreign meals, he feels that he must have rice stir-fried vegetables, and then soaks a vegetable soup to call rice, what tall Western food, steak, I feel no appetite when I think about it, I never enter any McDonald's KFC Western restaurant, I don't know if there is a big feeling of the same, just East China Zhixiong's personal feelings, like to go abroad to eat Western food big don't scold.) ）

Wang Xiaoyu showed a faint smile: "Hmph, you can bring a cook over." ”

"And did you use to be a cook?"

The two were talking some words that made people feel relaxed and sweet, and at the same time walked back to the hotel, and saw a car parked outside the hotel, and under the street lamp, the people who got off the car were clearly illuminated.

Qin Zhenhua's face changed suddenly, and he took Wang Xiaoyu's hand: "Let's go, let's press the road again." ”

In this era, it has become popular to fall in love, and it has also become popular to press the road, usually, the two of them are very busy, and they have no time to fall in love at all, and today, Qin Zhenhua's performance makes Wang Xiaoyu a little strange.

Holding Wang Xiaoyu's hand, Qin Zhenhua's interest did not diminish at all, so Wang Xiaoyu was even more sure.

"Those people, are they looking for you?"

"yes." Qin Zhenhua was a little annoyed, he had already seen clearly, among those few people, there was that Derek, who must have come to collect debts, he had to avoid the creditor, how could this guy know that he was here?

Sneak around outside twice, wait for the creditor to leave and then go in, Qin Zhenhua thought so in his heart.

After all, such time is still too little, and next, my wife will continue to be busy in order to develop a fire control system, and what about herself? There are still two missions abroad, and it is estimated that we will not see each other for a long time, so now, it is better to cherish this short time together.

"You say, is the big closed-loop fire control system good?" Wang Xiaoyu said.

Yes, the beautiful love atmosphere has been destroyed, and this wife of mine has begun to talk about serious things with herself again, and she has always been worried about these things in her heart.

Two young couples, who have not seen each other for many years, pressed the road after meeting, and were actually discussing specific technical issues, which makes people cry and laugh a little when they think about it.

However, Qin Zhenhua still got solemn.

During the day, regarding the third-generation tank fire control system project, Wang Xiaoyu did not mention this large closed loop, obviously having concerns.

The large closed-loop fire control system is a function added to the advanced fire control system, mainly software corrections.

When each shell is fired, the system will automatically determine the deviation between the projectile and the center of the target in the target plane, which is the operation after the shot, and then use this deviation to correct the aiming angle of the next shell. In this way, the control loop of the system is closed on the projectile and the target, which is called a large closed loop.

Naturally, this is to hit the target more accurately, and each shot is re-corrected, but can it really be corrected?

"We know that errors are divided into systematic and random errors." Qin Zhenhua analyzed: "The characteristics of systematic error, every time the deviation to the left is to the left, it is caused by the system, and the random error is without any law. ”

For any engineering student, it is known that the zero scale wear of the ruler you use to measure, the measured data will always be small, this is the systematic error, when you are measuring, visually look at the scale of the ruler, at this time, it is a random error, which may be small or large.

"Our idea of a large closed-loop can effectively correct the systematic error part of the shooting, which is certain, but it is counterproductive for the random error part of the shooting. This time it is smaller, you make it bigger, and the next time it is bigger, you make it bigger, and the error will be more. Qin Zhenhua said: "Therefore, this will be counterproductive, as for the systematic error, we might as well minimize it when we are calibrating the artillery." ”

There is nothing wrong with the pursuit of high precision, but the method must be appropriate, and an inappropriate method will be counterproductive, Qin Zhenhua finished saying this, and looked at his lover: "You think so too." ”

Wang Xiaoyu showed a sweet smile: "Yes." I just want to hear what you think. ”

The night breeze gently blew Wang Xiaoyu's hair, the smile on her face was from the heart, Qin Zhenhua took his lover in his arms, and felt a moment of tranquility in the night breeze.

When I walked back to the hotel, it was already more than nine o'clock in the evening, and as soon as I walked in, the front desk of the hotel greeted me: "Mr. Qin, there are guests looking for you, and I have been waiting for you for more than two hours." ”

What the? Qin Zhenhua was dumbfounded, he still didn't dodge?

Just wanted to say it, just say that I was not there, the guests were already waving on the chairs in the hall over there, and seeing those people, Qin Zhenhua was not unhappy, only puzzled.

How are you?

Qin Zhenhua is hiding from a foreigner, Derek, hiding from debts, and he doesn't want to pay back the money directly to the other party, just to give the other party an unforgettable lesson and let the other party know that discriminating against the big eastern countries is the end of it!

And now, those people who came can also be regarded as friends, after all, they have been together before, and they have struggled for the same goal!

In Qin Zhenhua's mind, he recalled the past scenes again, and with a smile, he stretched out his hand: "Lao Wang, Lao Nie, Lao Wu, what kind of wind blew you here?" ”
