"Peng!"

Xiao Yan, who was unsuccessful in one blow, obviously did not admit defeat, and saw him hammer the piece of glass hard for the second time.

This time, he obviously used all his strength, and the skin on his face was red because he was too hard!

"Bang! Bang! Bang! Bang! ……”

When Xiao Yan was panting, the piece of glass was still unscathed, but it was a pain for the two employees who were trying to withstand the glass!

"It's time."

The corners of Lin Xuan's mouth hooked up with a smile, and he turned his head to look at the audience and asked with a smile:

"Is there any other gentleman who wants to play?"

With Lin Xuan's words, there were not so many hands raised this time.

If there were tens of thousands of people before the first time the glass was smashed, after the second time it was found that the girls were not smashed, there were only about 7,000 people left, and most of the girls were eliminated.

For the third time, even Xiao Yan, a young man, couldn't smash that piece of glass with such a big hammer.

This made many people at the scene fall silent, even Xiao Yan's guy couldn't smash the glass, they weighed their beer belly by themselves, and found that there was little hope of breaking the glass, so they didn't raise their hands.

Looking at the hands of tens of thousands of people who raised their hands to now there are only less than a few hundred, Lin Xuan pointed at it casually.

One of them looked close to 1.9 meters tall, and his size was like a tank, and he looked very oppressive!

In the face of this kind of 1.9 meter fat man, I believe that anyone around him will not dare to move like a cat seeing a tiger, for fear that the other party will give him a punch!

"There's a play!"

The uncle with thinning hair was still in a low mood just now, thinking that no one at the scene could break the glass and get 1 million.

But he didn't expect Lin Xuan to point out such a big one-meter-nine fat man, at this time he felt that the glass must be broken!

"Hello, my name is He Yu and I'm from Shandong."

The big fat man of 1.9 meters patted his chest and introduced himself.

"Needless to say, the rules are up to you!"

"Hahaha, I'll take the good 1 million."

The big fat man named 1.9 meters laughed, and then picked up a miner's chisel!

"Look brother, I'll take 1 million!"

Spit on the miner's chiseled pole, the one-meter-nine fat man waved the chisel vigorously, and in an instant, the sharp iron head of the spoon slammed into the glass!

"Bang!"

The piece of glass shook to the ground, but it didn't shatter in the slightest.

In this regard, the big fat man of 1.9 meters was instantly furious.

"He's n, watch me chisel again!"

The big fat man of this meter nine obviously refused to admit defeat, and then launched a crazy attack on that piece of glass one after another!

"Bang bang ......"

Looking at the one-meter-nine fat man who had no way to take that glass no matter how he knocked it, everyone at the scene fell silent!

After a long time, the thinning uncle spat out the words that had been swirling in his mind for a long time:

"It's not scientific!"

Looking at the silent scene, the corners of Lin Xuan's mouth hooked up with a surging smile, and then asked with a smile:

"What other gentleman wants to come up and try it, this is 1 million!"

As Lin Xuan's words fell, no one on the scene raised their hands!

At this time, everyone can see that this piece of glass is simply not the glass that the earth should have, it is simply unscientific to the extreme, and human beings have no way to take it!

"Are you sure, this is 1 million, after getting this 1 million, you will have no worries for the rest of your life if you save some money."

Lin Xuan invited the audience with a wicked taste, but those viewers had become very shrewd after the scene just now.

At this time, there were only tens of thousands of people on the scene, but no one raised their hands, obviously people had already seen Lin Xuan's trick!

"Okay!"

Lin Xuan spread his hands helplessly, and then slowly introduced this piece of glass:

"This is a piece of tempered glass, and tempered glass also has a long history in my Great Xia.

I made the first tempered glass in Daxia in 1958, and it has been decades since then. ”

As Lin Xuan's words landed, people nodded one after another, but at this time, the female college student showed an unbelievable look.

Because this piece of glass was so powerful, she thought that Lin Xuan had used some transparent super material to make such a glass.

But I didn't expect it to be a newly invented transparent super material, it turned out to be ordinary tempered glass?!

"This is impossible, how can tempered glass have such a strong ability to resist hits, and it is only 0.19 mm!"

This bespectacled female college student said her opinion with an affirmative face.

"That's not right!"

The female college student who fell into self-doubt suddenly remembered something, only to see her exclaim:

"Rupert's tears!

！ ”

Long ago, in the mid-19th century, scientists in Europe stumbled upon something strange.

This kind of thing is the ancestor or prototype of the current tempered glass, and this thing is called Rupert's tears.

The so-called Rupert's tears are the process of throwing melted glass into cold water, which in certain accidental circumstances, the glass is instantly cooled.

The glass that doesn't break will become incredibly hard, and there will be a small tail behind the glass.

The glass, known as Rupert's Tears, was predicted by experts to be 100 times harder than diamond, and even a bullet could not break him.

Not to mention bullets, there was once a curious person who used a 20-ton hydraulic press to see if he could crush him, but the 20 hydraulic press supported by Rupert's tears instead pressed the steel of the hydraulic press's workbench into a steel pit!

This is Rupert the Tears of the Terror!

The tempered glass currently on the market is actually made according to the principle of Rupert and the like.

Their purpose is to turn ordinary glass into prestressed glass, which is characterized by the formation of a compressive stress layer on the surface of the glass, so that the mechanical strength, heat resistance and impact strength and so on have been increased several times.

From the invention of tempered glass to the present, after hundreds of years, people also understand tempered glass very clearly.

In the past hundred years, tempered glass has been improved by people's understanding and research, and the strength of tempered glass has been continuously improved in a hundred years.

But for now, no matter how it is improved, the strongest tempered glass on the market is still not as original as the most primitive, and it is also the original tempered glass Rupert's tears!

At present, the strongest tempered glass on the market is about 5~7 times stronger than ordinary glass, and it is still a long way from the terrifying performance data of Rupert's Tears!

Just like the original Edman alloy shield in Captain Medi.

Even if others wanted to make the same thing, they couldn't make a shield of the same strength at all, and the shield in Captain Medi was the ceiling of all Edelman alloys.

And at this time, this Rupert's tears are the ceiling of tempered glass!

So if a company can use a special method to make its tempered glass reach or close to the level of Rupert's tears, then all this is very normal in front of you.

"Becoming an Immortal"

With the degree of the horror performance parameters of Rupert's Tears, and then according to such a large area.

Not to mention chiseling with miners, even if you bombard it with cannons, you may not be able to destroy it!

Of course, as for whether Hantang Technology can make tempered glass reach the terrifying level of Rupert's tears, to be honest, female college students don't believe it.

But she believes that this tempered glass definitely has a unique technology, even if it can't reach the level of Rupert and the like, it will definitely easily surpass the tempered glass of other companies in the world!

Thinking of this, she looked at Lin Xuan with admiration on her face, and little stars flashed in her eyes!

On the other side, after Lin Xuan gave a rough introduction to the world and the history of Daxia tempered glass, the topic changed to this tempered glass.

"I believe many people know that our Hantang Technology has previously taken out 11 billion funds to overcome the equipment and process of 45nm chips.

There is one thing that we can't do without him, and with our level of technology in Great Xia, we are also very backward in this thing.

I believe that through the knowledge bombardment of the media and experts during this time, the most difficult part of the 45nm process is the lithography machine, and I also understand what the lithography machine is, and know the major components of the lithography machine.

Among them, there is one thing that is the most expensive, it accounts for 40% of the total cost of the whole machine, this thing seriously hinders our progress, and what is this thing, it is the lithography machine lens! ”

After a pause, in the midst of people's gentle nods, Lin Xuan slowly said how to develop lithography machines, how could he encounter such a big problem:

"The lenses of the lithography machine are definitely the most demanding lenses of all products, and their most important indicator is light transmission, in addition to their extremely high stability and high temperature resistance.

For the lenses required by the lithography machine, there is no optical manufacturer in our Daxia range that can manufacture the lithography machine lens that meets the requirements.

Even if we want to buy it, we can't buy it, even if we want to buy it through some small means, we can't get it back, because these lenses are too big!

Palm-sized, high-precision lenses that we can get back with small means.

But in the face of lenses that are larger than the pot of our gas stove for stir-frying, how can our "staff" get this kind of oversized lens back, so the special lens problem required by the lithography machine has seriously stuck the research of our lithography machine! ”

After a pause, Lin Xuan sighed deeply and said:

"And you can't use this lens even if you want to ship it back, because it's a specially designed lens!

Because as we all know, there will be imaging bias when magnifying or shrinking things with a magnifying glass, and this imaging bias is because our human brain can automatically parse and make up for it.

Therefore, when we play with a magnifying glass, this imaging deviation does not affect our use of the magnifying glass, but for the machinery that cannot automatically make up the brain, this imaging deviation is very fatal.

Especially for the lithography machine, a little deviation in lithography is very fatal!

So here's why a lot of expensive cameras or cameras have lenses that are so long, and why their lenses are more expensive than the cameras themselves.

In order to reduce the imaging deviation of a good camera, they can only use a number of specially designed lenses to make up for the imaging deviation as much as possible.

The lens of the lithography machine naturally has the problem of imaging deviation, so he also has dozens of specially designed lenses.

Of course, because of the different requirements, the structure of their lenses is also different, so the structure of 45nm and 120nm lenses is also different.

So even if we get the lenses back from the outside using small means, we won't use them at all! ”

The tens of thousands of viewers below heard Lin Xuan talk about the difficulty of the lens of the lithography machine, and they realized at this time that the original lithography machine was to be developed, and just one lens problem could kill the landing of the lithography machine!
