After the water is converted into air internal energy. If it erupts from a vent.

Then the effect it produces is only the thrust reversal in the air. This is a great waste of steam. It would be a huge waste of power.

Everyone is in a dilemma on this issue, they don't have an open mind for the time being, and they all stop thinking for the time being, what kind of vent to use to make a large amount of steam discharge intensively, and produce a greater reverse thrust.

For the time being, there is no ability to think of repurposing steam in another form, another device. The second energy conversion, to leapfrog the lifting power.

They just walked into a misconception and forgot that increasing steam emissions is to increase power. And it strayed into the corner of the idea that "if you increase the steam emissions, you can increase the power by increasing the thrust reversal".

After Li Zhen's little push, everyone suddenly realized.

Divergent thinking was born from here.

Soon, someone asked: "Master Li." If the movement of the piston works, then another important problem arises. ”

Li Zhen's eyes lit up, did anyone think of it: "Please speak." ”

"If you know that the containers and evacuation pipes are confined spaces. Then with the continuous heating, the internal air is constantly expanding. If the blockage is movable, then it will only eject out. If the pipe is infinitely long, the piston can only spray indefinitely. Under the effect of pressure, it can only spray out, but not shrink back. ”

"I may not be detailed and precise, and it is difficult to explain exactly what I mean. What I want to say is...... This is not true. Unless we set up extra-long pipes, extra-long transmission rods. As the steam erupts outward, the piston is pushed to continuously spray out, and the linkage rod is continuously pushed outward. Isn't there a need for a wall in the back? Only a wall can the drive rod push the wall and move the car or boat forward? ”

Everyone was a little dazed, but Li Zhen actually understood.

To be honest, he was also temporarily stuck in this problem.

He understood the principle of a steam engine, but he had never seen a steam engine. He only vaguely remembered hearing someone describe it.

He's been stuck on this issue for days, and this question is. The movement of the piston must be able to push it out, then retract, push it out again, and retract it again. It can only be called continuous power if it is constantly moving back and forth.

However, the internal energy of the air in the confined space will continue to expand, and the continuous squeezing of the piston can only spray out. But they can't shrink back. That's a big problem.

There must be a solution. But Li Zhen didn't think of it for the time being. I think I'm about to think about it, but I just can't grasp that point.

Soon, other students also reacted. A pipe was found and a branch was inserted into it: "If the thrust on my hand represents the thrust of steam." Then my hand inserted this branch into the tube, and I could only insert it, but I could not pull it out...... Because if my hand were the force of steam, the steam wouldn't shrink. In this way, the reciprocating cycle cannot be realized, the reciprocating cycle cannot be realized, which can only produce instantaneous power, but the sustaining force is not established. ”

The student used branches and pipes to represent steam and pistons, and everyone instantly understood what the problem was.

The steam only pushes the piston forward, but it can't push backward because of the constant expansion. It's not possible to repeat the cycle. This is paradoxical to the principle.

The piston requires at least two movements to complete the mechanical ability conversion. These two actions are, push forward and retract. Push forward again, retract again.

However, the students of the Kyushu Institute of Physics finally discovered that such a difficult problem exists in the steam engine, which is simply a chasm. All they could think of was that the piston could only make one movement...... It's forward.

"We have to cross the river by feeling the stones, meet problems, and solve problems. Everyone has to think differently. ”

Li Zhenlang said.

Everyone thoughtfully returned to their places, took out their notebooks to write, and remembered.

Then we started designing again.

The road to the steam engine is long, not that simple.

It's not complicated, but there are so many problems to solve.

Li Zhen walked out of the laboratory and strolled down the streets of Quancheng County. It's a bit stuffy to stay in the lab all this time, and it's more effective to come out and relax your brain than to do it behind closed doors, right?

"I've been in Quancheng County for so long, and I really haven't had a good visit to the main city of Dongzhou."

Qi stunned and smirked behind him: "As the saying goes, you want to understand the customs of a place. First of all, you have to understand the women of this place. ”

Li Zhen rolled his eyes: "Don't expect me to take you around the kiln." ”

Qi was stunned and said sullenly: "I don't go to that kind of place." I was just...... Do you have any female classmates you can introduce one to me? ”

Li Zhen smiled, and his opinion of Qi Stunned in his heart has been improved by one dimension, this guy has a long hand.

But you don't have to think about it to know that there will definitely be no female classmates in Fuxing University who can take a fancy to him. It has nothing to do with charisma.

Those who enter Fuxing University are self-proclaimed scholars and intellectuals. All look down on illiteracy. Even if Qi is stunned by his martial arts and looks like Pan An, he can't be recognized by those female intellectuals at all.

When it comes to the concept of marriage, college students in Kyushu are very stubborn and very conservative. It is said that it is a free marriage and free love, but in fact, it is not free......

Qi was stunned and kept saying, "Really." I like a female classmate, can you tell me about her? ”

Li Zhen was curious: "Which female classmate?" ”

"A fifth-year physics girl has now joined your Kyushu Institute of Physics. If you and she look down and don't look up for a day, help me introduce you. ”

"There are a lot of girls in the fifth year, and there are also a lot of girls in my Kyushu Physics Institute. How do I know which one you're talking about? ”

"That's it...... That one...... Ah. ”

Qi was stunned and suddenly became arrogant, the burly man's face was flushed, and he said awkwardly: "The one who is quite big and likes to wear thick glasses." ”

Li Zhen thought for a while, and exclaimed, "You shouldn't be talking about Hou Qiang, right?" ”

"Hmm...... That's her. ”

Li Zhen was shocked, he thought that Qi Stunned liked the weak and delicate style of Jiangnan women, but he didn't expect him to like this tune.

Hou Qiang, although the name is the rose of the rose. But the first thing I felt when I pronounced it was 'Hou Qiang', a very masculine-sounding name.

And in fact, this girl is very gentleman, a head taller than Li Zhen. It's about 1.85 meters. Tiger's back. He likes to have short hair that doesn't even raise eyebrows, and wears a pair of glasses with lenses as thick as the bottom of a glass bottle.

Qi was stunned and said shyly: "Her hometown is from Xizhou." I like that body very much, it's very healthy. He also wears glasses, and at first glance he looks like a literati. My biggest dream in life is to marry an intellectual. The one who wears glasses knows that he is an intellectual at a glance. ”

Li Zhen looked at Qi Zhenzi's tiger's back with a strange expression, and muttered: "You guys are indeed quite worthy......
