At this time, an old man with gray hair walked in, his face was flushed, his mouth was full of wine, and Professor Chonglong shouted bad luck, "Old thing, you can't help it, I thought you could hold on for at least three more days to dye your hair this time, but I didn't expect you to be so useless, and I lost again!" ”

Professor Long looked at him with disgust on his face, "You are you?" Slovenly! ”

"Lao Tzu is unkempt? Lao Tzu, this is called manly ......," Professor Cheng blushed and roared thickly. Pen × fun × Pavilion www. ｂｉｑｕｇｅ。 ｉｎｆｏ

Ye Congyuan shook his head, sat down not far away, and began to solve the equation seriously, no longer paying attention to the two old men who had been pinched together.

She learned math very well, solving equations was a trivial matter, and she quickly solved the results.

"This number...... Professor Long thought for a while, and called Professor Cheng, "Old man Cheng, come and see this value......

Professor Cheng walked over, looked down, flipped over the original values again, and frowned, "In this case, there is still a problem with our conjecture......

In the blink of an eye, the two went from saber-rattling to solving problems together, and the scene switched quite naturally.

Ye Congyuan was on the side, did not speak, but picked up the notebook of the record and was ready to record it at any time. Although she has a good memory and will not forget it after writing it down with her brain, this kind of record is generally enlightening for research work and needs to be written down and archived.

Soon, several old experts came one after another, and everyone buried their heads in discussions.

The result of the discussion was naturally a change in the original assumption and a new direction. This is a common thing in research, and no one takes it seriously.

Ye Congyuan moved his pen like flying, recording quickly, and at the same time using two minds, integrating the relevant knowledge in his mind, and began to analyze, summarize and summarize.

Several old men were in a dispute about the direction of the future, and they all blushed and had thick necks.

"This definitely doesn't work, I think it's just a change in this value, and it can't accelerate a lot at all......"

"You can't do it, according to your assumption, the energy will run out when you leave the earth, and the spaceship can only circle around the earth, and you can't even come back......"

"I think it's okay to consider the approach I'm talking about...... In this case, the spacecraft may be able to safely fly out of the Earth and fly within the Earth's gravitational field, and as for returning to Earth, it should be enough to ......"

Ye Congyuan used his brain to analyze quickly while recording, and now everyone refers to the calculation method of light levitation, and plans to refer to the core power plant system of light levitation to create a power system suitable for manned spacecraft, so that the speed of the spacecraft will exceed the first cosmic velocity, reach the second cosmic velocity, and then orbit the sun without the earth's gravitational field.

Based on the arguments of these experts and the various equations she calculated, she concluded that they were very close to the right direction, but they were unable to find the right path due to their knowledge, and they needed to continue to explore.

At this time, she needs to be promoted by the "insight" of the study hall.

Noting down a series of key points, Ye Congyuan took a blank piece of paper over, wrote down a series of formulas, and then stood up and interrupted the argument of several old experts, "Professors, according to your previous arguments, I found that it is easier to increase the speed by changing this value, and even reach the ...... of the separation speed."

The detachment velocity, that is, the second cosmic velocity, can allow the spacecraft to break away from the earth's gravitational field and orbit the sun, and according to the theory of mechanics, the second cosmic velocity v2 = 11.2 km/s can be calculated.

Ye Congyuan's current research group is studying manned spacecraft, not a small one or two people that can only carry one or two people, but like an airplane, a large number of people.

Among the current spacecraft, many are able to leave the first cosmic velocity and orbit outside the Earth. There are also many vehicles that have reached the second cosmic velocity, and even the third cosmic velocity, there are rockets and space probes that have broken through.

However, unlike rockets and space probes, manned spacecraft have not made great progress for so many years. Countries around the world want to find enough energy to allow larger manned spacecraft to accelerate within the Earth's gravitational field and thus break away from the Earth's gravitational field.

However, large manned spacecraft are heavy, and they can carry little energy on their own, and they consume a huge amount of energy at the moment of takeoff. Now after the large spacecraft rushes out of the earth, the remaining energy is seriously insufficient, and it is impossible to accelerate again and reach the second cosmic velocity.

So far, manned spacecraft built by various countries have not been able to break out of the Earth's gravitational field, without exception, for this reason.

Now, the institute intends to use the energy of light, which eliminates the disadvantage of having to carry a large amount of fuel for a manned spacecraft -- which is why the institute asked for information from the light levitation laboratory.

Several noisy experts listened to Ye Congyuan's words and walked over quickly, "Which value do you mean?" Let's take a look at ......"

According to the core power unit of the protective cover, the leaf cong edge has been modified with ultrasonic linear drilling and light levitation vehicles, and which numerical changes are best understood. It can be said that with so much experience, she can now do more with less when she studies the power plant of a manned spacecraft.

"Is this the number?" An old expert stared at the formula again and again, took a pen and paper and lowered his head to calculate.

The rest of the old experts were not far behind, and they took paper and pen to calculate.

"But at this point, this value has fallen into an endless loop...... "After a while, Professor Cheng pointed to a value on the third page he had written.

The rest of the old men probed over and looked, "It's indeed another endless loop......

However, when those who engage in research encounter such a situation, they will generally think about it and try to find a solution. At this moment, several old professors are like this, they think about it seriously and think about it, take a pen and paper and go to the side to read a word, and the pen is flying.

Ye Congyuan saw it and didn't say much. The effect of what she said was not at all as good as that of the old experts themselves.

The whole office suddenly fell silent, and only the "rustle" of the pen on the paper could be heard.

I don't know how long it took, Professor Long suddenly slapped his head, and the whole person jumped up, "Ah, I know! ”

A few old men who were meditating quickly came back to their senses and strode up to Professor Long, "What do you know?" ”

"That value, that value, I remember three years ago, I seemed to study it...... I'll have to go back and look for it, look for it......" Professor Long said, putting down his pen and getting up.

At this time, Professor Jin walked in, "Old man Long, you calculated a value back then, and I thought about it again recently, and I think it is very useful, you can take a look again-"

"Give it to me, give it to me—" Professor Long, who loves beauty, no longer has a trace of his original humble and gentlemanly demeanor, and rushes up like a chicken blood, snatches the information in Professor Jin's hand, and quickly flips it up.

"That's it, that's it...... You all come and see, is it solved? Professor Long was so excited that his old face turned red, and his eyes burst out with a terrifying light.

When several old experts heard this, they stepped forward one after another.

Professor Jin looked confused and looked at Ye Congyuan.

Ye Congyuan whispered to Professor Jin about the development of the matter, and then wrote out Professor Long's steps roughly.

"Haha, according to this inference, the information I brought came in handy?" Professor Jin listened to Ye Congyuan's narration and laughed happily.

Professor Cheng nodded excitedly, "This is definitely a phased victory, let's study it well, and if it is feasible, we can continue to the next stage of research." ”

The old men were all in a state of excitement, among which Professor Long looked at Ye Congyuan excitedly, "That beautiful little girl, come and help, I know you must have a deeper understanding of this ......"

After that, Ye Congyuan was forced to stay in the research institute by several old men, and as for the bedding she needed, she asked someone to buy it, and the clothes were for Major Liu and his party to go back and get them.

Ye Congyuan himself, followed a few old men without sleep, and worked for three days and three nights.

"Hahaha...... This problem is finally solved! The direction is right, the road is feasible! Throwing down the pen and paper, Professor Cheng laughed, reached out and picked up a bottle of wine on the table, opened it and poured a few large sips.

Professor Long excitedly scratched his hair into a chicken nest, "We are in the right direction, according to this direction, we will soon be able to make the manned spacecraft reach the second cosmic velocity!" ”

The second cosmic velocity, also known as detachment velocity, when the spacecraft reaches this velocity, it can break away from the earth's gravitational field and become an artificial planet orbiting the sun!

As for the manned spacecraft, if it reaches the second cosmic velocity, it means that human beings can fly out of the earth for sightseeing!

How many people's lifelong dream is to fly out of the earth, enter the solar system for sightseeing, and enjoy the vast solar system scenery?

"Let's go back and rest first, and we'll continue to study when we're rested." Professor Jin waved his hand and told everyone to go back to rest.

Professor Long, who loves to be clean and dressed, is now covered with oil, his hair is even more oily, and he nodded with blood-red eyes, "Let's go, rest, otherwise this old bone won't be able to survive." ”

Professor Cheng glanced at the old experts around him, and saw that everyone's eyes were red, and their eyes were blue and black, similar to madmen, and he couldn't help laughing, "Aren't we just a bunch of old madmen?" ”

Saying this, his eyes swept to Ye Congyuan, and he suddenly froze, "It's Ye Congyuan, this little girl, who looks full of energy, like the new peony flowers that bloom every year in the research institute." ”

Professor Long, who was walking out, heard this, and couldn't help but look back at Ye Congyuan, and when he saw it, he was jealous in his heart, "Beautiful little girl, tell me quickly, how did you do it?" ”

All the old experts looked at Ye Congyuan, and when they saw her watery appearance, they couldn't help but feel envious, and they all opened their mouths to ask.

After three days and three nights in the laboratory, why are they all like dying beggars, but Ye Congyuan is still as beautiful and fresh as a new flower that has been drunk and slept?
