Siheyuan: Concentrating on science and technology is the right way

"But according to my guess, Freon 12 will cause damage to the ozone layer."

"Because the chlorofluorocarbon gas is released, it will slowly rise to the top of the ozone layer in the atmosphere."

"When chlorofluorocarbons are floating in the air, due to the influence of ultraviolet rays in sunlight, they start to break down and release chlorine atoms."

"These chlorine atoms are very reactive and like to combine with other substances. So when it encounters ozone, it starts to change chemically."

"Nine Twenty"

"Ozone is forced to break down into an oxygen atom and an oxygen molecule, and the chlorine atom combines with the oxygen atom."

"But when other oxygen atoms encounter this chlorine oxidation molecule, they snatch the oxygen atom back to form an oxygen molecule, and the single chlorine atom can destroy other ozone again.

Hearing Lin Weidong's explanation, the faces of Professor Li and Professor Liu became extremely serious.

Even if they are not professionals in this area, they also understand the importance of the ozone layer.

"If this is the case, aren't we slowly destroying the environment we live in?" Professor Li said with fear.

"You can say that." Lin Weidong nodded.

"Then the refrigerant you studied won't cause damage to the ozone layer?"

"Of course not, otherwise would I have to make it specially?"

"But we can't produce the refrigerant you mentioned, after all, we don't know much about it." Professor Liu said with a frown.

"So I helped us contact a chemical research laboratory through my second elder.

"I understand." Professor Li nodded solemnly: "I will report this matter."

"If what you said is true, then it will be a great achievement.

After finishing speaking, Professor Li didn't rest anymore, and directly proposed to leave.

"By the way, this is your reward from above." Before leaving, Professor Li took out a small box with a medal inside.

"Because of the special circumstances, the higher authorities chose not to make it public," Professor Li explained.

"Understandable!" Lin Weidong nodded, carefully accepting the medal.

The current domestic situation is not very peaceful.

But this medal, after the wind blows, will become another life-saving talisman for him.

After Professor Li and Professor Liu left, Lin Weidong saw that the things on their transport truck were left behind.

It was Professor Li who asked people from the security department to move in front of Lin Weidong.

After Lin Weidong opened it, he saw a set of drones.

At this time, the drone is still in a folded state, only more than two meters long.

However, after the arms and blades are deployed, it will reach four or five meters.

This is a small UAV whose function is to conduct reconnaissance and provide fire support at short and medium distances.

The set of drones that Professor Li and the others sent was very complete, including machine gun components and grenade components.

There were two boxes of grenades beside them, which made Lin Weidong a little jealous and wanted to try to control them.

But after thinking about it, let's wait for a while, Mr. Huang and the big leader are probably also waiting to see the drone.

If he knew that Lin Weidong would play without waiting for them, he might be able to mutter about him all day.

So Lin Weidong went to the parking lot after calling Huang Lao and the big leader respectively.

Since his distribution car arrived, he hasn't tried it himself.

"Director, where are you going?" Seeing Lin Weidong coming to the parking lot, the driver of the transport team who was on call in the lounge next to him hurried out and asked.

"It's okay, you go back, I'll walk around and try the car." Lin Weidong waved his hand and said.

"This... the director, let me go with you." The captain of the transport team said.

"That's fine." Lin Weidong nodded, not letting him follow, they probably didn't feel at ease.

Lin Weidong started the car slowly, and Lin Weidong felt pretty good at first.

After all, the roads in the research institute are still very flat.

That is, the acceleration is very slow and the car vibrates a lot.

But after driving out of the research institute, it failed. It was very bumpy and the shock absorption ability was very poor.

"What do you think of this car?" Lin Weidong asked after returning from the test drive.

"QQ group 6 [-] ⒏ er! 嬄＄气气one⒍*"

"It feels good." Zhao Pan'er nodded.

The captain of the transportation team also quickly said: "Yes, this is definitely a good car."

"No car in the rolling mill is as good as this car."

Listening to their answers, Lin Weidong also knew that he was asking for nothing...

They have never been in the car of later generations, so how could they have any comments.

"Let's go, let's go back." Lin Weidong already had a rough upgrade plan in mind.

The most in need of an upgrade is, of course, the engine.

The engine is the heart of the whole car, and then the bearings, which are equivalent to the joints connecting the torso of the car.

Some small functions of later generations, such as listening to the radio, playing music, etc., can not be added now.

If it is too troublesome, it may not be possible to do it with the current technology.

But the air conditioning function, this must have.

Otherwise, it’s okay in winter, and it will be hot to death in this iron box in summer.

Of course, the shock absorption function must be upgraded.

Riding in a car is not just about being comfortable.

After having an idea, Lin Weidong acted directly.

Drawings one after another appeared in front of Zhao Pan'er.

In this regard, Zhao Pan'er also felt Lin Weidong's drawing speed and pride again.

People who don't know the situation think that Lin Weidong just sits in the office every day, gets so much money, and keeps getting promoted.

But Zhao Pan'er has seen Lin Weidong's hard work that others have not seen in the past few days.

The drawings were so densely packed that ordinary people would have a headache just looking at them, but they appeared one by one in Lin Weidong's pen.

How much knowledge does it take to draw so many and responsible drawings.

"Off work!" Hearing the bell, Lin Weidong reached out and waved in front of Zhao Pan'er who was in a daze.

"Oh, let's pick up Xi 2.8 Xi!" Zhao Pan'er quickly recovered.

The next day, before Lin Weidong arrived at the research institute, Mr. Huang and the big leader had already arrived at the rolling mill.

But he didn't go in, but sat in the car and waited.

Seeing Lin Weidong coming, he got out of the car quickly.

"Weidong, you are here. Where is the drone, show me quickly." Huang Lao said impatiently.

"It's at the research institute!" Lin Weidong smiled and led the way.

And when he walked to the entrance of the research institute, looking at the security department standing guard next to him, each with an 81 bar, Mr. Huang was a little envious.

"It's really thanks to you, my guards haven't even put on new equipment yet, but your security department did it first.

"That's right, as a designer, I can't be shabby to the people under me." Lin Weidong laughed.

Huang Lao laughed and cursed a few more times when he heard the words.

Chapter 160 Six: The Powerful Firepower of Drones

When they came to the equipment room of the security department, Mr. Huang and the others saw the set of drones.

"It's so beautiful." Huang Lao hurried over.

At the same time, he also saw the machine gun assembly and the grenade launch assembly next to it.

"Can all these things be installed on this drone?" Elder Huang asked in surprise.

"That's right, the original purpose of this drone, in addition to reconnaissance, is to quickly and effectively provide air fire support within short to medium distances."

"That would be great, right now is when we need airpower."

"Find a place to test the power of this drone." Huang Lao said impatiently.

"No problem, but are we going to the shooting range, or going into the mountains as before.

"Of course it's going into the mountains. What's so interesting about those dead targets in the shooting range?" Huang Lao said without the slightest hesitation.

"Okay, then I'll make arrangements." Lin Weidong asked people from the security department to help, and loaded the whole group of drones onto the transport vehicle.

Then he said, "We're going hunting in the mountains, so we won't take you there."

"Okay!" Zhao Pan'er nodded 07, she also knew that it was not appropriate for her to go along with this kind of thing.

But when they left the institute, they saw Director Yang and Deputy Director Li waiting at the entrance of the institute.

"The big leader and Mr. Huang are here, and they didn't notify us." Director Yang laughed.

"qu n⒈＄⑹㈧2#嬄旗旗伊光"

"Okay, okay, follow if you want." Seeing that they had prepared the car, the big leader said angrily.

"Then thank you, great leader." Factory Manager Yang and Deputy Factory Manager Li both looked happy, and then drove behind them.

...

It was still the same mountain forest as before, but there were more people coming this time.

The first is Mr. Huang and the big leader, as well as their respective drivers.

Then there are the two directors of the rolling mill.
