Better tools make good work!

All the people in the Kyushu Institute of Physics have understood the importance of basic science, and if you want to perfect the steam engine, you must know a concept, the pressure value.

And finally, under the leadership of Li Zhen, they invented a scientific measuring instrument that had never appeared in Kyushu - a pressure gauge.

During this time, twenty extremely hermetically sealed boilers were manufactured in batches. But the boilers are all made of different materials. There were cylinders and pistons in every boiler, but the pistons were plugged and there were no crank rods and flywheels attached.

Half an hour later, outside the gate of the Kyushu Institute of Physics, the people watching the excitement covered their ears and retreated.

Megumi Yanagisawa said, "What are you running? ”

"Run. It's going to explode again. ”

"The last time there was an explosion, it burned for more than 40 minutes. It's almost time. ”

"It's very moving, run!"

“……”

Liu Zehui was startled, looked at Liu Jinghong who was standing in front of the boiler inside, and became nervous, and subconsciously shouted: "Jinghong, what are you doing there!" ”

Liu Jinghong, who was heavily armed, raised his eyes, frowned, and snorted coldly: "Close the door!" ”

Immediately, a few people who had been hired to do chores came out of the Kyushu Physics Institute, and they closed the door without saying anything, and blocked the gap in the door with wooden planks to prevent the outside from looking.

Yanagisawa was furious, rushed forward and kicked the door open, yelling: "It's so dangerous, you dodge for me!" ”

Yanagisawa's movements did not attract the attention of others at all, and Li Zhen and the others all knew that Yanagisawa was coming. But no one looked up. Each of them stared nervously at the pressure gauge hanging on the boiler, watching the pointer crawl slowly, completely unaffected by the outside world.

Liu Zehui pounced on him to catch Liu Jinghong, but Liu Jinghong suddenly turned around and yelled: "Dad, are you annoyed?" This is the ninth trial, and we're averaging it. If you miss a second, start all over again. ”

Yanagisawa Hui was actually frightened by his son's momentum, and shouted: "People say this will explode, you are so close." ”

Liu Jinghong sighed: "I can't explain it to you." It has not yet reached a tipping point, and according to normal estimates, it will take another five minutes before the possibility of an explosion or steam leak occurs. What the hell are you doing here? ”

"Huh?"

Yanagisawa muttered, not knowing what to say. At this time, the master pulled Yanagisawa Megumi to the rear and comforted, "You can watch first." Everyone has conducted nine experiments, and they all have a spectrum in their hearts. And it's so thick. ”

"But ......"

Liu Zehui wanted to say something, but saw that Liu Jinghong didn't pay attention to him anymore, and stared at the thing that looked 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." 40 minutes, the pressure crosses the line 86. Boiler No. 10 did not leak. ”

"Stand back!"

"Stand back, prepare the sand."

The thirty-two had a clear division of labor, and all of them began to retreat in unison. Some of them hurriedly ran to the corner of the wall, found sand and shovels, and were ready to put out the fire.

The rest of the people all retreated to a safe distance, crouched on the ground, and watched the change in the pressure gauge closely.

Only then did Yanagisawa realize that there was still a yellow line on the ground. The yellow line should be a safe distance.

"45 minutes, pressure 90."

"Correction, 91."

"There was no air leakage for 45 minutes, and the pressure value grew slowly. It's the reason why the firepower doesn't work this time. ”

"The pressure value is over 95.Everyone is ready!"

"Attention!"

As soon as the words fell, I heard a loud 'bang'.

A puff of white smoke billowed from the field, covering the entire Kyushu Institute of Physics. The loud bang made the people watching the excitement outside the door cover their ears and scream and run away.

The white smoke filled the air, causing a huge sense of fear in Yanagisawa's heart.

In the midst of this loud noise, Yanagisawa Megumi shouted in horror: "Shock! ”

The master also had red eyes, where had he ever seen such a big explosion, like explosives, he didn't dare to move when he covered his ears and lay on the ground.

And in the midst of this chaos, Yanagisawa Megumi suddenly saw that all the teenagers from the Kyushu Physics Institute were half-squatting on the ground, motionless like a mountain.

Without even looking at the explosion, it was as if the boiler had not exploded at all.

None of the teenagers showed a strange look on their faces, they were so calm, they were so calm.

In the midst of this chaos, only a sonorous and powerful shout came out:

“98！”

"Correction, pressure 98.5."

"The pressure of boiler No. 10 reached a critical point of 98.5."

"It's still the piston that comes out of the cylinder and explodes."

"The boiler is intact."

“……”

When the steam erupted for a moment, another group of heavily armed teenagers took shovels and spread the sand over to extinguish the fire.

After a few moments, the flames were extinguished and the steam was no longer outward.

The frightened people outside the door were talking excitedly, and gathered around again, excitedly discussing the explosion just now.

Megumi Yanagisawa got up and watched her busy son walk around the boiler intently, constantly recording data, and suddenly felt an indescribable feeling in her heart.

Fang Hanxian came from a distance, holding the piston that was sprayed out in his hand: "This time the piston is sprayed out twenty meters away. 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, and there is no instantaneous impact of expansion." Okay, let's get together and calculate the average. ”

"The critical point at which steam leaks from ten different boilers is 89. The highest was 98.5 and the lowest was 80. Every time a leak explodes, it is ejected from the cylinder. This shows that the relationship between the cylinder structure and the material is not as great as imagined. Whether it's iron, steel, or mixed metals, steam leaks from the cylinder port.

That means that within a controllable range of steam. The expansion force of the steam is not enough to break through a completely sealed boiler. It is not enough to cause a boiler explosion, only cylinder cracking, piston ejection, steam leakage, etc. ”

“……”

Yanagisawa Megumi looked at the group of teenagers and immediately sat around the table and started a heated discussion, sighing in his heart, wanting to say to his son, who was sitting in the corner and constantly pondering, to pay attention to safety. 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 couldn't bear to bother after all.

After hesitating for a long time, Yanagisawa Hui whispered in that direction: "Jinghong, then I'll go." ”

Liu Jinghong turned around, nodded casually to Liu Zehui, and then stood up and continued: "The pressure gauge is extremely important. It's a groundbreaking product, and we're going to put it to good use. So the average value has come out, let's make statistics, under how much pressure does the steam engine start to excrete more scientifically? ”

Yanagisawa Megumi saw that her son's mind was not on her at all, and she felt a little lost and a little inexplicably proud.

Grew up.

"Well, let's go."

Walking out of the gate of the Kyushu Institute of Physics, the surrounding people immediately surrounded Yanagisawa Huituan, and everyone asked in surprise: "Are you the father of the Yanagi scientist?" ”

Megumi Yanagisawa snorted: "Ah." ”

"Gee, how did you teach such a great son?"

"Can you pass on a little bit of educational experience? Those who can enter this Kyushu Institute of Physics are all dragons and phoenixes among people, right? The kind of person who can't even look down on Fuxing University, how did you educate him? It's so promising. ”

"Disrespectful and disrespectful, I thought my brother was from the village next door, and I feel that you are the father of Scientist Liu."

"Big brother, can you tell me, I want my son to go here to do chores, study, and contaminate the scientific atmosphere here. My son also graduated from high school this year, can you be accommodating? ”

“……”

Megumi Yanagisawa stood at the door of the Kyushu Institute of Physics, looking around at his face full of anticipation, and then looked back at the humble prefabricated house, as well as the teenagers who were discussing fiercely in a circle in the courtyard. Inexplicably, my heart is a little sour.

Once upon a time, when others saw Liu Jinghong, they would only say: "You are the son of the county guard of Laoshan County, right?" ”

Today, he was asked by others: "You are Liu Jinghong's father, right?" ”

The master stood aside, a little overwhelmed, inexplicably, and felt relieved for Megumi Yanagisawa.

Seeing that his son has only been here for a few days, he is respected by the people in the neighborhood. Far more honorable than being treated with the same respect yourself!
