Rebirth 1981 starts with saving the sisters from the neighboring village.

"Miao Zan, I just did what an ordinary person should do."

Peng Wanhua smiled, feeling a little flattered to be praised so highly by Ni Yunan.

You must know that Ni Yunan is a shining pearl in the scientific and technological world. If he becomes an academician in the future, there is no doubt that he will be a leader in this field.

It is simply impossible for ordinary people to receive such praise from him.

"Brother, you are good at everything else, but there is one thing that makes me feel a little uncomfortable." Levi scratched his head and said.

"What?" Peng Wanhua was confused.

"Too modest and too pretentious. In comparison, it feels like my IQ is being rubbed on the ground."

Levi couldn't help but express his inner thoughts.

Although it was a little presumptuous, even a little offensive, he couldn't help it.

"You guy!"

Peng Wanhua laughed and cursed.

If it weren't for Ni Yunnan's presence, he would have punched him twice.

Levi saw what he meant and rubbed his head in embarrassment.

"Haha, Mr. Li is right, Wanhua, you are too modest.

I thought I was humble enough, but I didn't expect you to be more humble than me. "

Ni Yunan quite agreed.

After a few small talk, it’s back to business.

"I will focus on three main research areas later on: program-controlled switches, inkjet printers and typewriters."

Ni Yunan talked about the main research work behind.

Needless to say, program-controlled switches are of course needless to say. Currently, most domestic communication equipment is imported, mainly including American Bell and Fujitsu, which are very expensive.

AT&T, Nokia, and Ericsson saw the gaps in the country and set up offices in the country.

With the "help" of these foreign communications companies, equipment imported from abroad is used throughout the country.

However, these switches of different standards were incommunicable with each other, and domestic communications soon entered the chaotic stage of "seven countries and eight systems".

It caused chaos in China's communication network.

Printers also have the same problem. Canon, Epson, HP, Xerox, and Siemens are vying for territory in China and occupy almost all of the mid-to-high-end inkjet printer market.

In order to solve this problem, Ni Yunan, as a responsible technician, knew that he must come up with domestic switches and printers as soon as possible.

As for the development of typewriters, it was entirely because microcomputers were too expensive and a product that could type was needed for daily office use.

"Currently, the typewriter is the most successful, and the 2000-door program-controlled switch is relatively smooth. It is expected to be trial-produced and verified early next year, and mass production in the second half of next year at the latest.

It’s just that inkjet printers are still relatively complex and may take a year and a half or even longer to be put into trial production. "

For these scientific research projects, Ni Yunan has detailed and complete promotion plans in mind.

Basically blurted it out when needed.

Peng Wanhua nodded, "Inkjet printers have their advantages in color printing, but if I had to choose, maybe laser printers would go more smoothly."

"Oh?"*2

Not only Academician Ni, but Li Wei was also curious as to why he thought so.

"Do you know Teacher Wang Xuan of Beijing University's laser photo studio?" Peng Wanhua asked.

Levi shook his head, looking confused.

Ni Yunan asked, "Is it Mr. Wang Xuan, the director of your Peking University Computer Research Institute and the inventor of the laser phototypesetting system?"

As a bright star in the technology world, it was impossible for him not to have heard about it.

What's more, Teacher Wang Xuan is also working on a Chinese character information processing system. Although it is in a different direction from his Hanka, they are both very powerful applications in their respective fields.

"Yes, that's him."

Seeing that Li Wei was a little confused, Peng Wanhua continued to educate him: "The so-called laser typesetting is to control the laser typesetting machine to emit laser light onto the film or printing plate to form characters when there are strokes.

The development of the laser phototypesetting system began in August 1974, also known as Project 8.

At that time, only the British company in the world was developing the fourth generation laser phototypesetting system, but it had not yet succeeded.

There were five teams working on it in China at the time. Each of these five teams was strong, but none of them had succeeded.

Teacher Wang Xuan is one of them, and the other four companies all choose the technical path of second-generation or third-generation computers, and use analog storage.

Carve the Chinese characters on a disk or a plexiglass roller like Western characters, and then type them.

English is easier because there are not many letters, fonts, and font sizes.

But there are tens of thousands of Chinese characters, and there are at least six to seven thousand commonly used ones, as well as more than 10 fonts and about 20 font sizes.

Therefore, it is impossible to carve Chinese characters. "

Peng Wanhua took a rest as his mouth felt a little dry.

Levi poured him a cup of tea very discerningly, "Brother, drink tea to moisten your throat."

"Thank you." Peng Wanhua took it and took two sips of moisturizing before continuing:

"In response to this problem, Teacher Wang Xuan proposed the path of digital storage.

But because the Chinese character information is too huge, the whole world cannot solve this problem.

Because Wang Xuan majored in computational mathematics at Beijing University, the first thing he thought of was to use the mathematical method of "contour + parameters" to solve this problem.

For irregular strokes, such as dot strokes, first select appropriate points on the stroke, then connect the points with polylines, and finally save the hollow outline information into the computer.

For regular strokes such as horizontal and vertical folds, parameters can be directly used to represent information such as its length, width, and stroke tip.

Through this, the Chinese character information is compressed hundreds or even thousands of times and stored in the computer.

This solves the problem of storing huge Chinese character information into a computer.

Later, the image-setter was simpler, so he studied it with relevant teachers from the Physics Department of Peking University.

As long as the laser output control technology step is solved, the fourth generation laser phototypesetting can be directly used.

And he invented original chips by combining software and hardware.

The speed of glyph restoration was ultimately as high as 710 characters per second, which was also the fastest Chinese character restoration speed in the world at the time.

After the above three key problems of Chinese character compression, restoration, and laser phototypesetting output were solved, he directly developed the world's latest generation of laser phototypesetting.

In the 1980s, their research team successfully produced a sample book of "The Sword of Wu Hao" using a laser phototypesetting system.

This marks that China bids farewell to the era of type printing and enters the era of light and electricity.

It caused a huge sensation at the time!

Now, they should have patents and are working on commercializing their research results. "

Speaking of the latter part, Peng Wanhua was a little excited.

After all, it sounds very impressive to hear something so awesome.

"You mean, cooperate with him to develop a laser printer?"

Ni Yunnan can get through it with just a few clicks.

Peng Wanhua nodded and said: "Yes, the market for laser printers is very vast. Using his technology to develop it through cooperation is much faster than trying to figure it out from scratch on our own.

And he should be looking to cooperate with the Economic Daily newspaper now, and is in urgent need of a commercial opportunity.

As for inkjet printers, we will take our time later. We will launch products first to occupy the market and brand heights.

There will be more room for maneuver in the future, and inkjet printers will be launched accordingly.

what do you think? "
