The rejuvenation of a great nation: from educated youth to national treasure scientist

Chapter 103 Catch up with the world's advanced level?

After the color TV production line was developed, Wang Haoran led everyone to start trial production of color TVs.

The production line led by Wang Haoran mainly produces two models: 17 inches and 21 inches.

At this time, they are all large-screen color TVs.

Nowadays, such color TVs cannot be produced domestically and need to be imported. The price is also very high. A 17-inch color TV costs two to three thousand yuan, and a 21-inch one costs four to five thousand yuan.

Today's RMB exchange rate against the US dollar is not low, about 1.7 to 1.

That means a 17-inch color TV costs more than $2000.

Now the average American citizen's monthly salary can reach 17 to 300 dollars, and a -inch color TV costs about dollars in the United States.

It can be seen from this that when the scissors are used to cut the leeks of the people of Longguo, it is simply uprooting them.

Wang Haoran personally took part in the trial production of the first domestically produced large-scale color TV.

He worked with the members of the research team for more than ten hours.

Although it was the first trial production, the amount of material was not small.

The materials ordered at one time were enough to produce 20 color TV sets.

More than ten hours later, one 17-inch color TV after another was produced.

Soon, the open space in the factory workshop of Beijing Institute of Technology was filled with color televisions.

Although we haven't started testing whether we can watch it yet, everyone is very excited and filled with pride.

The last color TV was assembled.

Wang Haoran clapped his hands and called all members of the research team over.

He glanced at the dozens of people in front of him, and everyone's eyes could not hide their excitement.

Qian Dake, the head of the Department of Electronic Engineering, stood next to Wang Haoran.

Qian Dake was also feeling very emotional at this time.

When the project of domestic color TV production line was first launched, Qian Dake had no idea what was going on.

After all, there are too many technical difficulties involved in the color TV production line.

I don’t know how many years it will take to complete this project.

However, it only took three or four months for the domestic color TV production line to be developed.

Although the televisions produced now have not been tested yet, there is no problem with the production line design and all production processes are perfect.

Then, these newly produced televisions must be able to watch programs normally.

"Teacher Qian, do you want to tell us about it?" Wang Haoran said to Qian Dake with a smile.

Qian Dake waved his hand and said, "I think, let's stop talking nonsense and test the color TV produced by our equipment first!"

“If we can achieve the quality of similar products like foot basins, then we will be truly successful.”

Wang Haoran nodded and said, "Okay! Then, let's test the product first!"

Wang Haoran personally took a few young people to set up the viewing antenna and then connected the antenna to the TV.

At this time, the TV signal is an analog signal and a wireless signal.

Ordinary TV users use antennas to receive TV signals, and then they can receive TV programs normally.

At that time, antennas were basically homemade, but of course finished products were also sold in supply and marketing cooperatives.

The homemade antenna mainly uses the following materials: copper wire, iron wire, wooden sticks, cables, etc.

The production process is as follows: first grind the copper wire into a straight line about 1.5 meters long, leaving a certain length at both ends for connection.

Then make an antenna bracket: punch a hole in the center of a wooden stick about one and a half meters long, fix it with wire, and make a U-shaped bracket.

Connect the two thin wires in the prepared cable to both ends of the copper wire.

Finally, fix the prepared antenna bracket on a long pole and insert the long pole outdoors.

If so, you can receive TV signals.

If the received signal is not clear enough, or there is snow or something, then go outside and adjust the antenna by yourself, mainly adjusting the direction and position, until the program received by the TV screen is clear.

Wang Haoran personally connected the antenna to the TV.

Then he asked Guo Mingliang to go outside and wait while the antenna was adjusted.

"Now, I'm going to turn on the TV. See how our color TV reception is." Wang Haoran spoke in a relaxed tone, and he went to connect the power cord.

Then he reached out and turned on the TV.

All the members of the research team gathered around.

Everyone was a little nervous.

Everyone's eyes were fixed on Wang Haoran's hand as he tried to turn on the TV.

"Crack!"

The TV was turned on.

Everyone's heart skipped a beat following this sound.

The TV screen powered on and lit up quickly.

First, the entire screen was covered with snowflakes.

Immediately, the snowflakes disappeared, and the screen showed a picture of a program from Beijing TV.

At this time, the news is being broadcast.

The picture is quite clear.

For a short while, people were watching the TV screen in silence.

Colorful!
The color is very positive!

The picture is very clear!

Moreover, the picture was as clear as water even before the antenna was adjusted.

The ratings are so good, aren’t they?
Qian Dake looked at the TV in front of him with mixed emotions!
In fact, the TV factory in Jinshi produced the first domestically produced color TV a few years ago.

However, that color TV was completely hand-made and had no ability to be mass-produced!

Moreover, Qian Dake also went to watch that color TV and found that the picture quality was very average and the sound was not very good either.

It's just barely watchable.

Compared with the color TV manufactured by Wang Haoran, it seems a bit too crude.

"Ha! Why is everyone so quiet?!"

"Our domestic color TV production line has finally succeeded! Shouldn't we applaud ourselves?"

Qian Dake spoke loudly, and his voice was trembling a little due to excitement.

His eyes were a little red.

"Wow!"

In the workshop, everyone began to applaud enthusiastically.

Everyone clapped so hard that their hands turned red.

Wang Haoran was very calm.

He tried a few more channels.

The ratings were pretty good.

In fact, there are not many TV stations now.

The most watched television station is the national television station.

In addition, there are television stations in various provinces.

There is actually a lack of television programs nowadays.

Next, Wang Haoran and his team members tested all the televisions one by one. The viewing effect of each one was very clear, with no problems at all from the picture to the sound quality.

In order to compare it with the color TV he developed, Wang Haoran also borrowed a Panasonic color TV to compare the viewing effects.

After comparison, whether in terms of color, clarity or sound quality, domestic color TVs are no worse than Panasonic color TVs.

This means that the domestic color TV production line has reached the internationally advanced level.

That night, the entire Beijing Institute of Technology was filled with joy.

Liu Xianchao went out for a meeting today.

He didn't return to school until after 7 o'clock in the evening.

He learned that the domestic color TV production line led by Wang Haoran had already trial-produced the first batch of domestic color TVs, and that the viewing experience was no worse than that of imported color TVs. Liu Xianchao immediately rushed to the workshop of the school factory.

Liu Xianchao walked in quietly and found that Wang Haoran was still testing the product.

Everyone was busy and no one noticed his arrival. Liu Xianchao watched for a while.

He found that this domestically produced color TV had a very beautiful appearance and the big bump on the back was much smaller.

The picture quality is very good and the ratings are solid.

Liu Xianchao was very happy.

He took big steps and came to Wang Haoran's side.

"Haoran, our color TV looks to be of very good quality!" said Liu Xianchao.

Wang Haoran smiled and said, "I have finally fulfilled my mission."

Liu Xianchao asked: "What is the specific production cost?"

Wang Haoran said: "The cost of laboratory production will obviously not be too low."

"The production cost of each color TV is about 230 yuan."

"If we really start mass production and the cost is diluted, I estimate that the production cost of each color TV will be only about 100 yuan."

Only by reducing costs can prices drop significantly.

Then it can be promoted and popularized nationwide.

This is also the main reason why Liu Xianchao pays attention to cost.

Liu Xianchao nodded and said, "That's good, that's good!"

“Even if it’s produced in a laboratory, the cost is much lower than today’s black-and-white TVs.”

"Well, I think we should do the following things:"

“The first step is to conclude the project and report on the results.”

"Secondly, we need to contact Factory 780. We need to let them know the good news so they can feel relieved!"

"Third, we need to contact the machine tool factory as soon as possible and ask them to prepare to start the processing production line."

"In fact, what I am most worried about now is that the machine tool factory cannot keep up."

Wang Haoran said: "When the time comes, we need to send technicians to the site to guide them and make sure the production line is built well."

"He is always watching us!"

Liu Xianchao nodded and said, "Then why don't you give him a call?"

"Well! I think we should send him a color TV so that he can see how great our domestic color TVs are."

Wang Haoran smiled and said, “That’s a good suggestion!”

"I'll call and report first and see if I can visit him tomorrow."

Wang Haoran looked at the time and it was almost eight o'clock in the evening.

He went to his office to make a phone call.

At this point, we shouldn’t disturb the elderly.

But Wang Haoran felt that what he was going to report to the other party was a very good thing.

It’s okay to make the elderly happy.

The leaders will certainly be happy to hear the news that the domestic color TV production line has been successfully developed.

At this time, after the leader had dinner, he watched the news for a while and then took a walk.

Then he returned to his study and prepared to start working.

He strongly advocated promoting the household contract responsibility system nationwide.

However, there is considerable resistance.

Therefore, the leaders have been coordinating and holding meetings recently.

He wants to unify thoughts and create a completely new situation.

The leader was reading a document when the secretary came over quietly.

"Boss, Wang Haoran called. He said that the domestic color TV production line has been successfully developed, and a batch of sample color TVs have been produced."

"Wang Haoran said that the color TVs produced by their laboratory have been tested and the results are very good. The product quality and performance are no worse than those of the foot basin."

After hearing this, the leader was immediately cheered up.

"Huh! Has it been figured out already?"

"I'm going to give him a call and ask him about this."

The leader called Wang Haoran personally.

At this time, Wang Haoran was sitting on a chair in the office, quietly waiting to call his leader again.

The telephone in front of him began to ring.

Wang Haoran quickly picked up the microphone and put it to his ear.

"Hello!"

A familiar voice came from the microphone: "Comrade Haoran, good evening!"

Wang Haoran hurriedly greeted.

The two talked on the phone for a while.

Mainly the leaders asked questions and Wang Haoran answered them.

After a while, Wang Haoran said, "Leader, how about I send a color TV over tomorrow so you can experience it yourself?"

When the leader heard this, he laughed and said, "Haha! That's a good suggestion!"

"Haoran, I don't think it's too late now!"

"How about you come over now?"

It can be seen that the leader is also full of curiosity about domestic color TVs.

Wang Haoran hesitated for a moment: "Leader, it's already past 8 o'clock in the evening. It would be bad to disturb your rest, right?"

The boss said: "I was born to be a hard worker. I never go to bed before 12 o'clock every night. There are too many things to do."

"Come on! Color TVs play a big role in improving people's quality of life!"

"I'll have someone pick you up now."

"Soon after, the car sent by the leader to pick up Wang Haoran arrived."

When Wang Haoran went to meet the leader this time, he not only brought a domestic TV, but also an antenna.

Soon, we arrived at the leader’s residence.

As soon as the car stopped, Wang Haoran saw his leader appear at the door.

Someone naturally moved the things, and Wang Haoran hurried over to greet the leader.

Afterwards, Wang Haoran personally connected the power supply of the color TV he brought and connected the antenna.

Then turn on the switch.

After a while, the TV screen appeared.

The picture quality is very high, just like the calm blue water surface.

The leader stood and watched TV for a while with great interest.

He nodded and said, "This domestically produced TV is indeed of very high quality!"

“How many color TV sets can a production line produce in a year?”

Wang Haoran said: "If we run at full capacity, we can produce 30 color TV sets a year!"

The leader smiled and said, "The output is quite high."

"Statistics for 77 have gradually come out."

"Last year, our country only produced 20 television sets!"

"However, in my opinion, our country's annual television production must reach at least 500 million sets to meet the needs of the people!"

Wang Haoran took the opportunity to say, "Leader, our TV production is not only low, but the price is too high."

"If the price cannot be significantly reduced, ordinary people will still not be able to afford it!"

"My suggestion is: allow companies to lower their selling prices."

"On the one hand, it can save people's money, and on the other hand, it can stimulate consumption."

"What do you think?"

The leader nodded and said, "You are right. Once production increases and supply and demand are balanced, we will naturally lift price controls!"
