Chapter 277

When Li Zheng took the elevator to the 16th floor and entered Lin's mother's house, he was finally able to put down his suitcase and end his cattle trip.

The only feeling that this sea view house gave him was "empty".

In addition to sitting in the living room, there should be three times as much as sitting on the living room.

"Well." Lin Qijing a flying body rolled to the sofa, stretched out his arm and said, "at last, I'm exhausted."

"I have the face to say that people like you should have been fatter than Zhang Xiaoke." Li Zheng put down his backpack and walked to the floor to ceiling window of the row. At a glance, he crossed a few kilometers of forest belt and locked in the huge steel frame.

Li Zheng was fascinated and opened the glass door and went to the balcony.

Even at sunset, the launch pad is also visible.

It can be imagined that in a few days, it will be the brightest place in the whole island.

Maybe it will be the brightest place on earth.

in this dazzling light, the Yellow River two will rise to the sky, then adjust its angle, step up to the deep space above the Pacific Ocean, and step by step until its mission is completed, and the "Test No. six" technology test satellite will be sent into the geosynchronous orbit.

Even if all this has not happened, even if Li Zheng just stands here on the spur of the moment.

But still can not control their own eyes.

It was just when the mood was full, suddenly came the "no voice" from the side of the body.

Li Zheng quickly wiped his eyes, but don't be seen.

Then he turned his head.

Just want to talk, but see Lin Yue Jing has already cried into a lump.

"It's time to launch "No, no, no..." She covered her mouth and looked at the launch pad, sobbing, "for the 14 ton synchronous satellite transport capacity, ten years It's been ten years... "

"Don't cry like that..." Li Zheng was scared to pinch himself, "I want to cry if you cry like this."

"What are you doing?" Lin Yujing rubbed his eyes and said, "for this transport capacity, they gave up the mature technology before, and gnawed out the cryogenic liquid binding technology from scratch. The number of tests from the beginning to the end is more than the papers you have done."

"Well I'm not flattering. I have to make 5000 copies of papers. "

"Go, go, go!"

"Ha ha." Li Zhengfu said with a smile on the balcony, "but now the view is perfect. Is there really a better place to watch?"

"Yes, it is..." Lin Yue Jing tried to stop, wiped away his tears and said with a smile, "darling, I've been obedient these two days, and I'll take you there."

"Oh, boring, this is enough for me."

"Well, you can read the words on the arrow."

"Let's get closer, then?"

"Let in, and only a few people know."

Li Zheng such a listen, also really some heart itch, rubbing fingers stuffy voice asked.

"Then you What would you like to eat in the evening... "

"Fish!"

"What fish?"

"Big fish!"

“……”

……

Because it was too late, they missed the evening fair in the town, and there was nothing new in the supermarket. Finally, they found a northeast restaurant outside the community to make do with it.

It's not that they like the Northeast restaurants more, mainly because they don't have a choice. All of them are northeast restaurants.

They found out that there are probably more northeast people here than in Northeast China.

Fortunately, the boss was warm and the food was smooth. They sat at the table in the open square and ate slowly with the sea breeze.

Once entered the local rhythm, there will be a kind of inexplicable leisurely, do nothing in a hurry, daze is also excellent.

The old man of the library is also very good. For busy people like Lao Li and Ning'er, I'm afraid it's hard to have such a free day all year round.

Lin qiojing was so free that he didn't even bother to speak.

She just chewed on the sweet and sour sirloin piece by piece, shaking to the coconut grove across the road.

"Well, um, um..."

don't say, it's still very rhythmic.

Even Li Zheng rarely asked for a bottle of beer, occasionally happy.

There was a big table nearby, chatting and chatting.

It seems that two retired couples from the same hometown came here with their grandsons and granddaughters for a holiday, eating and drinking and complaining.

"Oh It has been said that a rocket will be launched in two days There's a lot more of them all at once. " A bald man sipped his wine and sighed.

The opposite glasses master poured wine and said with a smile: "ha ha, this is not a good thing, let the children have a look."

The bald man only shook his head: "but we are too close to the launch site. Do you think, in case of an accident, what can we do if the rocket hits us?"The fat woman beside her frowned and said, "look at your crow's mouth, bah! Pooh

"Yes." The opposite eye aunt then said, "which has such a bad thing, to have an accident is that their launch center is in danger."

"That's what they do. There's always a risk, but who are we looking for here..." The bald man took a mouthful of vegetables and complained, "my son, too, has to buy it here. Who knows there is such a big thunder nearby."

Glasses uncle raised his hand and said, "Hi, Lao Deng, if you are really worried, we will take our children to the city that day. The city is always OK. We have never heard of rockets flying into the city."

"No, no!" The little boy sitting next to him suddenly yelled, "it depends on the rocket!"

"I want to watch the Rockets too!" The little girl on the other side called out.

"Yuanyuan, what are you kidding about?" The bald man turned to pat the little girl and said, "do you know why the rocket launch was chosen here?"

"Why?"

"Because there are few people here. You see, there is still sea on the other side. Only when the rocket explodes, can the loss be minimized."

The bald man's voice has just dropped.

"Poof!"

A young man across the table spurted beer all over the floor.

Under the gaze of several people, Li Zheng raised his hand to cover his face. His expression was very strange.

"What's the matter, young man?" The bald man put his head forward and said with a smile, "can't you get used to drinking wine?"

"Nothing, nothing..." Li Zheng covered his mouth and said, "choked."

A table of people smile, also did not say much.

However, the little boy was still reluctant to take chopsticks and began to protest.

"Rockets go to space, they don't come to us, they don't explode."

"Pudding, you are too young to understand." Glasses uncle advised, "those rocket launching sites are either in the desert or in the mountains and forests, because they are too dangerous. Don't we watch the same thing on TV? "

The boy is still not happy: "I will watch it here!"

"Well, you can watch it here." "Then the launch pad will fall down and the rocket will hit you. We will not accompany you."

“…… cheat! The launch pad won't fall Cried the little boy.

"It won't fall!" Cried the little girl.

"It won't fall!" Lin shouts after him.

“……”

The scene fell into stagnation.

Even Li Zheng was stagnant.

Even if you don't like it, you can't be a kid.

"Don't worry." Lin yuejing turned to look at the little boy and the little girl. "Every day there are uncles and aunts checking the launch tower repeatedly. It is absolutely impossible that there will be any problem. Even if there is a sudden storm or earthquake, and ten lightning strikes on it, it is absolutely impossible to have any problems."

It's over!

I really joined the children's team.

The two children were instantly inspired.

"Yes

"Sister said, there will be no problem!"

"Who is she? Do you believe her?" The bald man frowned at Lin Yue Jing and said, "how do you know? Who are you? "

"Chen Wei, graduate student of trajectory design, Department of astronomy, School of physics, Jida; group 3, 12 Institute, No.1 Institute, Sinochem Launch Vehicle Technology Research Institute; Chen Wei, an internship student in trajectory design." Lin Qijing lightly picked up the drink, sipped it lightly, and looked at him in a glance, "no one knows rocket better than me."

Once again, the scene stagnated.

Li Zheng is the most ruthless one.

Gulu Gulu spurts out a large number of titles, but still looks pale and heart doesn't jump,

is it so fierce?

The man at the next table obviously didn't understand her title.

But it was successfully bluffed.

A moment later, the bald man stammered and said, "why did you choose the launch site here?"

"Get the maximum inertia speed and save fuel."

"What?" "You can't talk nonsense and teach the children blindly."

"Well..." Lin Yue Jing waved to Li Zheng, "Dr. Li Yi, you can say it."

“……” Li Zheng fell into ferocity in an instant.

It's over. It's been dragged to the children's team.

But now that the matter has come, he has to be tough.

Li Zheng soured his throat and said politely, "this Uncle, your explanation to the child just now is not comprehensive. Some of them are misleading. The launch site is located here. The primary basis is based on physical considerations. "

Seeing that Li Zheng has a nose and an eye, the bald man will not say anything for the time being. The two children are full of expectation and listen attentively.

Li Zheng swept around and soon found a ball beside the boy's stool. He picked it up and borrowed it.

"I try to use the level that primary school students can understand." Li Zheng held up the ball and turned it in his palms. "The earth will rotate like this, don't you know?"The little boy and the little girl nodded immediately.

"Good." Li Zheng picked up chopsticks, dipped in beer, and casually ordered a small spot in the "northern hemisphere" of the ball. "Let's assume Yuanyuan is here. This is probably Jijing's location."

Then, he pointed a point on the equator of the ball: "this is where Wenhai is, and the pudding is here."

"And then, you are all smart kids, knowing that the earth rotates all the time." Li Zheng then turned the ball around again. By dipping his chopsticks in beer, Li Zheng drew the trajectory of two points rotating one circle, which is actually two latitudes and a pair of concentric circles.

"Now, the earth has gone round." Li Zheng showed the ball to the two children, "can you tell me, for such a long time, is Yuanyuan turning more distance or pudding more?"

"Pudding!" Yuanyuan raised her hand and said, "the pudding is bigger."

"Very good." Li Zheng nodded and said with a smile, "so we can know that, in the same time, the pudding has turned more distance than Yuanyuan, so who turns faster?"

"Me The pudding raised his hand excitedly.

"So, even standing still, pudding's natural initial speed is much faster than Yuanyuan." Li Zheng's hand pointed to the equatorial dot and said, "launching a rocket from pudding has a great speed as soon as it comes up. We can use less fuel to send the rocket into space. Do you think it's wonderful?"

"Wonderful The two children clapped and screamed.

"Ha ha ha ha!" Looking at the two excited children, Li Zheng was naturally happy, "so ah, this is the advantage of Wenhai satellite launch. It can be said that Nanhai province is basically the most favorable place for China to launch rockets. The most important reason we chose here is to use less fuel and transport heavier satellites into space. Now that you two know this, you have become little experts in physics. You can talk to your classmates when you go back. "

The little girl blinked her eyes at Li Zheng and asked, "brother, are you a physicist?"

"It's still early I learned a lot... "

"Do you understand, grandfather?" The little boy said to the bald man, "it's because of the laws of physics that we chose to launch here."

"Go and go, I've already understood..." The bald man scratched his head and asked, "isn't that the faster you go south, why don't the launch site let Sanya go? What can we do with Wenhai?"

Li Zheng immediately replied.

"The earth's rotation direction is from west to East. This time, a synchronous satellite will be launched. It will remain stationary with the earth's rotation, so it will also be launched to the East. To the east of Wenhai is the sea area controlled by China, which is uninhabited and easy to recover."

"As for Sanya, there is a very low probability that the rocket will land in a residential area in the south of Nanhai province if an accident occurs at wan11001."

The bald man sipped his wine and couldn't ask.

However, Mr. glasses was interested in it: "I'll ask you more about the impact of Jijing and Nanhai on speed and fuel."

"This Just a moment. I'll figure it out. " Li Zheng raised his head and squinted his eyes. After half a second, he said, "I only calculated that the speed of Jijing line is about 370 meters per second, Wenhai is about 460 meters, and the fuel saved is about 12%. It is because of this 12%, that huanghe-2 can become the largest carrier rocket in China."

"Ah." The glasses master exclaimed, "now I understand completely. Thank you very much, young man."

Although the bald man on the opposite side was somewhat reluctant, he could not refute a string of truth that Li Zheng could understand.

"Well Young man... " The bald man scratched his face and asked, "that is to say, the rocket is launched towards the sea. Even if there is a problem, it will fall into the sea. Our community must be OK, right?"

"Sure, sure, sure." Li Zheng said with a smile, "Wenhai launch site is a selection of thousands of carefully considered, and the design and construction team is also the most sophisticated in China. You may not care, but it is not easy for children to catch up with the great development of aerospace in their whole life. It is also a physical enlightenment for children to have a look. I just don't have any children, or I'll have to look at every full moon. "

"All right." Happy, the bald man took up two beer bottles and went to Li Zheng. After filling one bottle for Li Zheng, he raised his hand and said, "let's not go. Watch the rocket launch!"

The two children jumped up at once.

The glasses master also came to dry a cup.

When Li Zheng returned to his seat, he was already drunk.

However, he found that Lin Yue Jing was hiding his face and giggling, and his face was more drunk than himself.

Li Zheng took a mouthful of vegetables and said with a smile, "how, now I know I'm flustered?"

"Why panic." Lin Qijing said in a low voice, "you are really patient when you give lectures to children..."

"Hey, I'm free, too."

"Don't you hate children and don't want them?"

"Yes, it affects learning."

"Cluck...""What are you laughing at?"

"It's OK. It's OK." Lin Qijing quickly picked up the cup and said, "I'll take a sip of it too"
