Rising: Ten Thousand Years Chapter 82: : The group of scientists
A worker must first sharpen his tools if he wants to do a good job!
Everyone in the Kyushu Institute of Physics understands the importance of basic science. If you want to perfect the steam engine, you must know a concept, the pressure value.
Finally, under the leadership of Li Zhen, they invented a scientific measurement instrument that had never appeared in Kyushu—the pressure gauge.
During this period of time, twenty extremely sealed boilers were produced in batches. But boilers are made of different materials. There are cylinders and pistons in every boiler, but the pistons are blocked, not connected to the crank connecting rod and flywheel.
Half an hour later, outside the gate of the Kyushu Institute of Physics, the onlookers covered their ears and retreated.
Liu Zehui said: "What are you running?"
"Run. It's going to explode again."
"The last time it exploded, it burned for more than forty minutes. It's almost time."
"The movement is loud, run!"
“…”
Liu Zehui was startled, and looked at Liu Jinghong who was standing in front of the boiler, feeling nervous, and subconsciously shouted: "Jinghong, what are you doing there!"
The fully armed Liu Jinghong raised his eyes, frowned, and shouted coldly: "Close the door!"
Immediately, a few hired handymen came out of the Kyushu Institute of Physics, closed the door without any explanation, and blocked the gap in the door with wooden boards to prevent the outside from seeing.
Furious, Liu Zehui rushed forward and kicked the door open, shouting: "It's so dangerous, get out of the way!"
Liu Zehui's movement did not attract the attention of other people at all. Li Zhen and others knew that Liu Zehui was coming. But no one looked up. Everyone stared nervously at the pressure gauge hanging on the boiler, watching the pointer crawl slowly, completely free from external influences.
Liu Zehui rushed forward to catch Liu Jinghong, but Liu Jinghong suddenly turned around and yelled, "Dad, are you annoying? This is already the ninth test, and we are taking the average. Missing every second Time, have to start all over again."
Liu Zehui was actually frightened by his son's aura, and said na na: "People say this will explode, you are so close."
Liu Jinghong sighed: "I can't explain it to you. It hasn't reached the critical point yet. According to normal estimates, it will take five minutes before there is a possibility of explosion and steam leakage. What are you worrying about here? .”
"Huh?"
Liu Zehui murmured, not knowing what to say. At this time, the master pulled Liu Zehui to the back, and comforted him: "Just watch it first. They have conducted nine experiments, and they all have a good idea. And they are so thick."
"But..."
Liu Zehui wanted to say something, but Liu Jinghong didn't pay attention to him anymore, and stared at the thing like a pocket watch hanging on the boiler with wide eyes. Sighing, he stepped back silently, his eyes full of nervousness.
Li Zhen suddenly roared: "Record. After 40 minutes, the pressure crossed the line of 86. No. 10 boiler did not leak."
"Back!"
"Stand back and prepare the sand."
The thirty-two people had a clear division of labor, and everyone began to retreat together. Some of them hurried to the corner, found sand and shovels, and were always ready to put out the fire.
The rest of the people all retreated to a safe distance, squatted on the ground and watched the changes of the pressure gauge closely.
It was only then that Liu Zehui realized that there was still a circle of yellow lines on the ground. That yellow line should be a safe distance.
"45 minutes, pressure value 90."
"Correction, 91."
"There is no air leakage in 45 minutes, and the pressure value grows slowly. This is the reason for the poor firepower this time."
"The pressure value is over 95. Everyone is ready!"
"Attention!"
As soon as the words fell, there was only a loud bang.
A burst of white smoke billowed in the field, covering the entire Kyushu Institute of Physics. The loud noise made the onlookers cover their ears and run away screaming.
The white smoke filled the air, causing Liu Zehui a huge sense of fear in his heart.
Amidst the loud noise, Liu Zehui shouted in horror: "Jinghong!"
The master is also red-eyed, where has he seen such a big explosion, like explosives, lying on the ground covering his ears and not daring to move.
But amidst the chaos, Liu Zehui suddenly saw that the teenagers from Kyushu Institute of Physics were all squatting on the ground, motionless as a mountain.
He didn't even look at the explosion, as if the boiler didn't explode at all.
None of the teenagers showed a strange look on their faces, they were so calm and calm.
In the chaos, only a sonorous and powerful shout came out:
"98!"
"Correction, pressure 98.5."
"The pressure of No. 10 boiler reaches the critical point at 98.5."
"It is still the piston that is ejected from the cylinder and explodes."
"The boiler is intact."
“…”
After the steam came out for a while, another group of armed teenagers held shovels and spread the sand over to put out the fire one by one.
After a while, the flames were extinguished, and the steam stopped coming out.
Outside the door, the people who were still in shock were discussing excitedly, and gathered around again, excitedly discussing another explosion just now.
Liu Zehui got up and watched her busy son concentrate on walking around the boiler, recording data continuously, and suddenly felt an indescribable feeling in her heart.
Fang Hanxian came from a distance, holding the ejected piston in his hand: "This time the piston ejected twenty meters away. It is not lethal."
Li Zhen recorded the data in his notebook and said: "This shows that the accumulation of steam in the boiler is a slow process, without the instantaneous impact of instantaneous expansion. Well, let's gather it and calculate the average value."
"Ten kinds of boilers with different materials have the critical point of steam leakage, and the average value is 89. The highest is 98.5, and the lowest is 80. Every time a leak explodes, it is sprayed from the cylinder. This shows that the cylinder The relationship between structure and material is not as great as imagined. Whether it is iron, steel, or mixed metal, steam will leak from the cylinder mouth.
That means, within the controllable steam range. The expansion force of steam is not enough to break a completely sealed boiler. Not enough to cause a boiler explosion, only cylinder cracking, piston ejection, steam leakage, etc. "
“…”
Liu Zehui watched the group of teenagers sitting around the table immediately start a discussion in full swing, sighed in her heart, and wanted to say to the son who was sitting in the corner thinking constantly, be careful. But looking at his son, under the leadership of the young man named Li Zhen in the main seat, he became extremely focused, but he didn't have the heart to disturb him after all.
After hesitating for a while, Liu Zehui said in that direction: "Jinghong, then I'm leaving."
Liu Jinghong turned around, nodded casually to Liu Zehui, then stood up and continued: "The pressure gauge is extremely important. This is a pioneering product, and we must make good use of it. Then the average It has already come out, let’s make statistics, at what pressure does the steam engine start to excrete, which is more scientific?”
Seeing her son, Liu Zehui was not focused on her at all~IndoMTL.com~ felt a little lost, but also a little inexplicably proud.
Grow up.
"Hey, let's go."
Walking out of the gate of the Kyushu Institute of Physics, the surrounding people immediately surrounded Liu Zehui, and everyone asked in surprise: "Are you the father of that Liu scientist?"
Liu Zehui snorted: "Ah."
"Oh, how did you raise such an outstanding son?"
"Could you pass on some educational experience? Those who can enter the Kyushu Institute of Physics are the dragons and phoenixes, right? The kind of dragons and phoenixes who don't even look up to Fuxing University, how did you educate him? Ah? So promising."
"I'm sorry, I thought my brother was from the village next door. I feel that you are the father of Scientist Liu."
"Big brother, can you tell me, I want my son to also come here to do odd jobs, learn a little bit, and soak up the scientific atmosphere here. My son also graduated from high school this year, can you be more accommodating. "
“…”
Standing at the gate of the Kyushu Institute of Physics, Liu Zehui looked at the surrounding circle full of expectations looking at her face, and then looked back at the simple prefabricated house, and the teenagers who were discussing fiercely in a circle in the courtyard them. Inexplicably, my heart felt a little sour.
Once upon a time, when others saw Liu Jinghong, they would only say: "Are you the son of the magistrate of Laoshan County?"
Today, someone asked, "Are you Liu Jinghong's father?"
The master stood on the side, a little at a loss, inexplicably, he felt relieved for Liu Zehui.
Seeing that his son has only been here for a few days, he is respected by the people around him. Far more honored than receiving the same respect myself!
