"Well, I heard that Anna only gave us enough cooking oil for a year or two, why don't you give us more?"

"Because it's not worth taking up space!"

"Use your brain! Not only occupies space, edible oil has a shelf life! What's the use of giving too much?! ”

"By the way, I remembered a problem, we don't have cold storage!"

"Why don't you ask Anna for one?"

"Everyone! Everybody! Listen to me! With this evaporator, we get five small recirculating evaporators! ”

Lao Zhu looked at the information and interjected, seeing that this group of people was talking as if no one was around, he had no choice but to raise his voice and focus everyone's attention on his side.

"Uncle Zhu, what did you keep talking about just now?"

At this time, someone finally noticed what Lao Zhu said.

"Lao Zhu, show me the information of that evaporator."

Zhao Xihe took the information in Lao Zhu's hand and looked at it carefully, raised his head and said to everyone:

"Well, this is the key equipment for refrigeration, everyone, we will have cold storage in the future!"

"Really?"

"Refrigerated?"

"Great, can we have a refrigerator?"

"The refrigerator compressor can barely be made, but it needs freon, right?"

Huang Hai of the Technic Group interjected.

"Freon is an ozone killer and we can't make this thing!"

Someone in the crowd said.

"Cut! Think beautifully! We can't produce Freon at all, just the catalyst is stuck there......"

"Okay, okay, now let's listen to me!"

Zhao Xihe raised his hand to stop everyone's discussion.

"In terms of the current chemical process equipment, we can't produce freon, that thing is too complicated, but refrigerants are not only freon!

Please rest assured, we can solve the refrigerant! ”

"Oh~~~"

"It's great~~~~"

Bang Bang Bang ...... Zhao Xihe didn't finish speaking, and everyone applauded happily.

"We can use brine ice-making technology to build cold storage, and the evaporator condenser on the list just now is the key equipment for cold storage."

Zhao Xihe added.

"Therefore, we have a way to store grain, oilseeds, and food, and the set of evaporators to make ice in brine is a very old and mature technology, and there is no reason why we can't do it, please rest assured!"

Boss Luo also interjected at this time.

"Okay, we're done with grain, oil and food, who should be next?"

Lao Zhu wiped his sweat and finally ended his topic.

"Huh? That's it? Okay, thank you Wang Lao Zhu for giving us the report, so, should we ask Xiao Fei, who is engaged in communication, to introduce the situation? ”

Elder Sun looked at the audience and said to a young man sitting in the corner.

"Yes, Mr. Sun, hello teachers, brothers and sisters, my name is Xiao Fei, majoring in radio engineering."

After Xiao Fei stood up and bowed slightly politely, he saw that everyone was gradually quieting down, so he looked at the information in his hand and said:

"I'll introduce the communication project that Anna gave us, well, let's not talk about the superfluous, there are indeed a lot of radio communication equipment in the cave, but it is not advanced at all, it can only be said that it is enough."

"Xiao Fei, what does it mean to be enough?"

"It's just that under the existing conditions, we can barely make our own and have enough performance."

Xiao Fei raised his head and responded to the questioner, but at this time, there were still people in the crowd talking as if no one was around:

"Oh...... It seems that the military phase array radar will be out of action in the short term. ”

"I know this, I understood it when I saw the spark plug transmitter in the cave......

So Xiao Fei had no choice but to stand up and speak:

"Everyone, be quiet, please listen to me, there are many radio communication equipment in the cave, from Marconi spark transmitters, ore detector receivers, to military radio stations in the United States during World War II. However, we don't get any industrial equipment in radio communications, and in fact, there is no industrial equipment worth asking, because it is useless to ask for it.

The key to the radio industry is electronic components, and the production of electronic components depends on the progress of our overall industrial level.

So let's talk about the big goal of the radio business, and my ultimate goal is to build a radio device based on transistors in my lifetime! ”

"Huh? Are you sure? ”

Someone in the crowd asked questions, and the tone was obviously not very believing.

"Well, I really don't have any sure, so I added a lifetime."

Xiao Fei responded lightly, then looked down at the information and continued:

"It's just the refining of silicon germanium, and I'm not sure if the metallurgical industry can do it in my lifetime, not to mention the others, students, I'm talking about the direction of struggle! That's the ultimate goal. ”

"The acquisition of germanium semiconductor materials mainly comes from lead and zinc smelting, and the acquisition of silicon is very simple, but it needs to be purified and single-crystallized, of course we know these technologies, but there is still a long way to go to refine these materials, and we will work hard. Therefore, I give Xiao Fei a suggestion, it is more practical to develop electron tubes honestly in the early stage. ”

At this time, An Hengtong of the metallurgical group responded to Xiao Fei's speech.

"Hey, it seems that I'm happy for nothing, and I'm still thinking that I can watch TV shows in my lifetime!"

"It's not hopeless! Maybe in 30 years there will be a TV! ”

Xiao Fei suddenly said something shocking, and when he saw everyone's surprise, he further explained:

"Because the early TVs were tubes! However, the bottleneck is the picture tube, which takes a bit of a setback. ”

Everyone nodded and shook their heads, and a group of science and engineering men next to them began to disagree again:

"It's not just a little twist, that thing is going to die for this!"

"I don't think it's that difficult, is it?"

"Can you try it out of the vacuum platinum shell?"

"Is this person difficult?"

"Don't say whether it's difficult or not, don't forget, our glass industry is going to start with glass cups and glass mirrors!"

"Yes, I think it's enough, after all, ordinary glass vacuum tubes don't know how to make them in the Year of the Monkey!"

"That's right! Let's make an electron tube first, and with this beginning, we can have a picture tube. ”

"However, we have complete technical information, as long as we give us a few years to explore and practice, the vacuum glass tube required for the electron tube should be no problem in the near future!"

At this time, Mr. Zhao said to everyone very seriously.

"Oh my God! Mr. Zhao, you said it! Do we really hope to see a TV show?! ”

"Well, Mr. Zhao is talking about a vacuum tube, which is still far away from the TV, anyway, if any of you can really get the picture tube out for me, I will build you a TV set......"

However, Xiao Fei's answer is obviously a little lacking in confidence.

"Uh, well, let's not discuss this now, it doesn't make any sense at the moment......"

"yes, it really doesn't make sense, and I usually don't watch TV at night......"

"So what are you doing?"

"Hehe, so many wives need me to serve, what TV do you ...... watch?"

"Damn! You're crooked again! ”

……

Anyway, the question of TV has turned over like this, and this group of science and engineering men obviously don't have any confidence in building TV. At this time, someone in the venue quickly remembered that Xiao Fei had not finished what he had just said, so he immediately asked another question:

"So, Xiao Fei, what is the minimum goal of your communications career?"

It was Sun Lao, who had been silent, who was asking.

"Minimum target?"

Xiao Fei responded to this, paused, looked around at everyone and said:

"There are two aspects, one is radio communication, the minimum target is the Marconi spark transmitter and the ore detector receiver, and the realization of radio broadcasting is the ultimate goal of the minimum goal.

Guys, I'll try to make a radio, it's a little easier than a TV.

The second is wired communication, and the minimum target is the wired telegraph and wired telephone network! Finally, the program-controlled switch is the ultimate goal. ”

Xiao Fei's reply this time was very firm.

"Well, it seems to be okay, right?"

"Alas, it looks like I won't be able to play online games in my lifetime......"

"You can play, LAN, there are only a few ready-made computers in our building!"

"Pull it down! Which ones will allow me to play? If I play badly, I will become an enemy of the people! ”

"Of course you can't play, no one wants to, it's definitely going to be used by the mothballing plan!"

"That's a must, use one less one, we can't build a computer in our lifetime to drip ......"

"Well, maybe our arrival will speed up the technological development of this plane? Maybe there's a tech explosion! ”

Apparently some people are not dead set on this.

"These things take time to ferment, I think it will take at least a hundred years! If the cultivation of human resources continues to be generated. ”

"Why a hundred years?"

Someone asked.

"Haven't you heard of the idiom: ten years of trees, a hundred years of people! Without three generations of scientific and technological inheritance and technology accumulation, how can there be talent support? Without the support of talents, there will be no explosive development of science and technology! ”

"Let's live well, maybe we will see you for a long time!"

Someone in the crowd muttered quietly.
