60s: I have a store

Chapter 196 Zhang Yan's Highlight Moment

The next day, Zhang Yan went to school early in the morning and couldn't wait to share the good news with her group members.

"Yan Zi, what are you so happy about?" her classmates asked her.

"Did you see that?"

"Nonsense! The word 'happy' is just missing from your face."

Zhang Yan chuckled: "Aren't we in the research group on electric lights? We have a new idea. Do you think it's worth being happy?"

"Ah? You have a new idea so quickly?" The classmates next to her were surprised and looked at her.

The students in the same group as Zhang Yan were even more excited.

"Swallow, what new ideas do you have? Tell us about them quickly." Someone said anxiously.

No one noticed that the teacher had already arrived at the door.

Zhang Yan started chatting with the people in her group, sharing the idea of ​​the halogen tungsten lamp and injecting a circulating agent into the glass shell to allow the evaporated tungsten to return to the tungsten filament.

When the teacher outside the door heard this, he was amazed by such a genius idea.

He understood better than his students that this idea had a good chance of coming true.

When the filament heats up, the tungsten atoms evaporate and move toward the glass tube wall. When approaching the glass tube wall, the tungsten vapor is cooled to about 800°C and combines with the halogen atoms to form tungsten halide.

The tungsten halide continues to move toward the center of the glass tube and returns to the oxidized filament. Since tungsten halide is a very unstable compound, it will decompose into halogen vapor and tungsten when heated. In this way, tungsten is deposited on the filament again to make up for the evaporated part.

Through this regeneration cycle, not only is the service life of the filament greatly extended, but because the filament can operate at a higher temperature, it can achieve higher brightness, higher color temperature and higher luminous efficiency.

Moreover, as a teacher, he thought of much more.

"Ah! Is this feasible?" a classmate questioned.

If it can be realized, this idea is undoubtedly a genius one and very bold.

"I think it's possible." A classmate in the same group as Zhang Yan said excitedly.

They have a deeper understanding of electric lights and certainly understand it better.

"Come on, let's go to the laboratory."

To use the laboratory, you need to apply for it! Only their school has such conditions for students to do experiments. Ordinary universities simply don’t have the space, materials, or funds.

"Ah! The teacher is here."

The teacher wearing glasses walked in.

He walked towards Zhang Yan, looking a little excited, and asked, "Zhang Yan, your idea is very good. Go apply for the laboratory, and I will ask them to approve it as soon as possible. Hurry up and produce the experimental data."

Zhang Yan said somewhat embarrassedly: "Teacher Zeng, injecting the circulatory agent was not my idea, it was someone else's."

"Not you? Who is it?" Teacher Zeng looked at the students in the same group as Zhang Yan.

The students in Zhang Yan's group were also shocked.

"Swallow, this wasn't something you came up with?"

"Who is that?"

Zhang Yan told them: "Do you remember Zhou Yimin, who invented the water pressure well and solar cooker?"

"Ah! You know him?" the classmates were surprised.

Of course they knew! Although they had never met, they had discussed that "god-man" more than once or twice.

Teacher Zeng also looked over, surprised that Zhang Yan knew such a folk inventor.

Yes! Now Zhou Yimin has been dubbed as a folk inventor.

Teacher Zeng knew Zhou Yimin better than these students because he had a relative who worked in the steel plant. He knew that Zhou Yimin had also invented the electric rice cooker, and that he was a very talented young man.

Zhang Yan said shyly, "He is my boyfriend." This shocked the whole class.

Is this your partner?

You hid it very well! You have such an amazing partner, but you didn't say a word. Are you afraid that someone else will snatch him away?
"Zhang Yan! When will you bring him to our school? Let us see him and pay our respects to him." Someone said.

That look was like a fan meeting his idol.

"Yes! You knew Zhou Yimin but didn't tell us. Why don't you bring him to our class?"

Even Mr. Zeng was interested in Zhang Yan's talent and hoped that Zhang Yan could bring her boyfriend over. He wanted to persuade her to come to their class and continue her studies.

On the same day, the school provided a laboratory to Zhang Yan and her team, and even teachers got involved.

"It really works." Zhang Yan's team members shouted, their faces flushed with excitement.

They were well aware that this research was of great significance and it was not an exaggeration to say that it was a reform of electric lighting.

Soon, Mr. Zeng also got the news that this kind of halogen tungsten lamp had been invented abroad a few months ago. In other words, if they could research it, domestic electric lamps would be able to reach the international advanced level.

After the laboratory version of the halogen tungsten lamp was made, it attracted school leaders.

Or rather, was alarmed.

The vice-dean of their department came hurriedly.

"How about it?"

Teacher Zeng nodded at him and said, "My students have already done it, but it will take some time to get the relevant data."

Nevertheless, they had predicted that tungsten-halogen lamps would perform much better than regular incandescent lamps.

Otherwise, foreign countries would not spend so much effort on research and development.

And now, our country has it too.

"Good, very good, very good!" the vice president applauded.

He walked in and saw the shining halogen tungsten lamps. He praised Zhang Yan and other students one by one and told them that the school would commend them after the data came out.

This is the glory of their school! They must promote it well.

Electric lights are a necessity in life and are in great demand, so this progress is of great significance.

Zhang Yan and others did not dare to take credit for it and quickly said that it was someone else who came up with the idea.

When the school leaders learned that it was Zhou Yimin who invented the pressurized water well, solar stove and electric rice cooker, they also became interested. Like Teacher Zeng, they hoped that Zhang Yan could "lure" her boyfriend to their school.

It would be a pity to give up such a talented person!

But no matter what, publicity is definitely necessary.

Even if we take a step back, the students of their school also deserve credit, right? The first halogen tungsten lamp in China was invented in their school, and this is an ironclad fact.

At this time, Zhou Yimin was walking on the country road of Zhoujiazhuang, looking at the pleasant wheat fields.

On the roadside, large fields of golden wheat waves flutter in the wind, and the smell of ripe wheat fills the air.

A villager picked two wheat ears and rubbed them with his palms. Finally, he did not forget to blow away the wheat husks. He half-clenched his palms and brought the plump, tender green and yellow wheat grains in front of him.

The wheat is ripe.

"We can harvest tomorrow," said the villager.

"Notify the commune and we'll harvest the day after tomorrow!" said the old branch secretary.

This needs to be notified to the commune, and they will send people to supervise, for fear that the villagers are hiding grain.

In this year, we have to be on guard. After all, after experiencing hunger, some villagers will take risks.
