Chapter 186 This is unscientific!
"Boom!"
Xiao Yan, who was unsessful in one blow, obviously did not admit defeat, and saw him hammering the ss hard for the second time.
He obviously used all his strength this time, and the skin on his face turned red from too much effort!
"Bang! Bang! Bang! Bang!..."
When Xiao Yan was out of breath, the piece of ss was still unscathed, but it was the two employees who worked hard to hold the piece of ss!
"time up."
Lin Xuan''s mouth curled into a smile, and he turned his head to look at the audience and asked with a smile:
"Any other gentlemen want to y?"
Following Lin Xuan''s words, not so many hands were raised this time.
If there were tens of thousands of people before the ss was smashed for the first time, there were only about 7,000 people left after the second time it was discovered that the girl was not smashed, and most of the girls were eliminated.
Then for the third time, even Xiao Yan, a young man with such a big hammer, couldn''t break the ss.
This made many people at the scene fall into silence, even that guy Xiao Yan couldn''t break the piece of ss. They weighed their beer bellies and found that there was little hope of breaking the ss, so they didn''t raise their hands either.
Looking at how tens of thousands of people raised their hands but now only a few hundred people raised their hands, Lin Xuan casually pointed.
Among them was a big fat man who looked close to 1.9 meters. It looked like a tank, and he looked very oppressive!
Facing this kind of fat man who is 1.9 meters tall, I believe that anyone around him would be like a cat seeing a tiger, not daring to move, for fear that the other party would punch him!
"There is drama!"
The uncle with thinning hair was still a little depressed just now, thinking that no one at the scene could break that piece of ss and get 1 million.
But he didn''t expect Lin Xuan to point out such a fat man who was 1.9 meters tall. At this moment, he felt that the ss must be broken!
"Hello, my name is He Yu, from Shandong."
The fat man who is 1.9 meters tall patted his chest and introduced himself.
"It goes without saying the rules, you can do whatever you want!"
"Hahaha, I took the good 1 million."
This big fat man named 1.9 metersughed loudly, and then picked up a miner''s chisel!
"Look brother, I''ll take 1 million!"
Spit on the pole chiseled by the miner, the 1.9-meter-long fat man swung the chisel violently. In an instant, the sharp iron head of the spoon hit the ss violently!
"boom!"
The piece of ss shook violently, but it didn''t break in the slightest.
Responding to this, the 1.9-meter fat man became furious instantly.
"Damn it, watch me chisel again!"
This big fat man who is nine meters nine obviously refused to admit defeat, and thenunched crazy attacks on that piece of ss one after another!
"Bang bang bang bang bang..."
Looking at the 1.9-meter fat man who couldn''t do anything with the ss no matter how hard he knocked, everyone fell into silence!
After a long time, the uncle with thinning hair spit out the words that have been circling in his mind for a long time:
"This is not scientific!"
Looking at the silent scene, Lin Xuan smiled faintly, and then asked with a smile:
"Is there any gentleman who wants toe up and have a try, this is 1 million!"
Following Lin Xuan''s words, no one raised their hands at the scene!
At this time, everyone can see that this piece of ss is simply not the ss that the earth should have.
"Are you sure, this is 1 million. After getting this 1 million, you can save some money and have no worries for the rest of your life."
Lin Xuan invited the audience with vicious humor, but those audiences have be very shrewd after the scene just now.
At this time, there were only tens of thousands of people present, but no one raised their hands. Obviously, people had already seen Lin Xuan''s tricks!
"Ok!"
Lin Xuan spread his hands helplessly, and then slowly introduced this piece of ss:
“This is a piece of tempered ss, and tempered ss has a long history in Daxia.
I, Daxia, produced the first tempered ss in Daxia in 1958, and it has been decades now. "
As Lin Xuan''s words fell to the ground, people nodded one after another, but at this time the female college student showed disbelief in her eyes.
Because this piece of ss is so powerful, she thought that Lin Xuan used some transparent super material to make this ss.
But I didn''t expect that it wasn''t some newly invented transparent super material, but ordinary tempered ss? !
"This is impossible, how can tempered ss have such a strong resistance to impact, and it is only 0.19mm!"
This female college student wearing sses expressed her opinion with certainty.
"No!"
The female college student who fell into self-doubt suddenly remembered something, and she eximed:
"Rupert''s Tears!!"
A long time ago, in the mid-19th century, there were scientists in Europe who identally discovered a strange thing.
This kind of thing is the ancestor or prototype of the current tempered ss. This thing is called Rupert''s tears.
The so-called Rupert''s Tears is to throw the melted ss into cold water, which is in the process of the ss cooling instantly under certain idental circumstances.
The unbroken ss will be extremely hard, and there will be a small tail behind the ss.
This ss called Rupert''s Tears is predicted by experts to be 100 times harder than diamonds, and even bullets cannot break him.
Not to mention bullets, a curious person once used a 20-ton hydraulic press to see if the mirror could crush him. As a result, Rupert’s tears actually supported the 20-ton hydraulic press, and instead pressed the workbench steel of the hydraulic press into a steel pit!
This is Rupert''s Tears of Terror!
The tempered ss currently on the market is actually made ording to principles such as Rupert.
Their purpose is to turn ordinary ss into prestressed ss, which is characterized by the formation of apressive stressyer on the surface of the ss, so that the mechanical strength, heat resistance and impact resistance are increased several times.
It has been hundreds of years since the invention of tempered ss, and people have a very clear understanding of tempered ss.
In the past hundred years, tempered ss has been improved through people''s understanding and research, and the strength of tempered ss has also continued to increase in the past hundred years.
But no matter how improved it is, the strongest tempered ss currently on the market is still not as good as the most original and original tempered ss, Rupert''s Tears!
Currently, the strongest tempered ss on the market is only about 5 to 7 times stronger than ordinary ss, and there is still a long way to go before Rupert''s Tears'' terrifying performance data!
Just like the original adamantium shield in Captain Mediocre.
Even if other people want to make the same thing, they can''t make a shield of the same strength at all. The shield in Captain Mediguo is the ceiling of all Adamantium alloys.
At this time, Rupert''s tears are the tempered ss ceiling!
So if apany can use a special method to make its tempered ss reach or approach the level of Rupert''s tears, then all this is quite normal.
Based on the terrifying performance parameters of Rupert''s Tears, and based on such arge area.
Not to mention chiseling it with a miner, even if it is bombarded with a cannon, it may not be smashed!
Of course, female college students don''t believe that Hantang Technology can make tempered ss reach the horror level of Rupert''s tears.
But she believes that this piece of tempered ss definitely has unique technology, even if it cannot reach the level of Rupert, it must easily surpass the tempered ss of otherpanies in the world!
Thinking of this, she looked at Lin Xuan with admiration, with little stars shining in her eyes!
On the other side, after Lin Xuan briefly introduced the history of tempered ss in the world and Daxia, the topic changed to this piece of tempered ss.
"I believe many people know that Hantang Technology has allocated 11 billion funds to ovee the equipment and technology of 45nm chips.
Among them, there is one thing that we cannot do without him, and with our Daxia''s level of technology, we are also very backward in this thing.
I believe that through the knowledge bombardment of the media and experts during this period, the most difficult part of the 45nm process technology is the lithography machine. I also understand what a lithography machine is and know the majorponents of the lithography machine.
Among them, there is one thing that is the most expensive, it ounts for 40% of the total cost of the entire machine, this thing seriously hinders our progress, and what this thing is, it is the lithography machine lens! "
After a pause, among the people nodding slightly, Lin Xuan slowly exined the reason for developing the lithography machine, and why he encountered such a big problem:
“The lens of the lithography machine is definitely the most demanding lens among all products. The most important indicator is the light transmittance. In addition, it is required to have extremely high stability and high temperature resistance.
As for the lenses required by the lithography machine, there is no optical manufacturer in our Daxia area that can manufacture the lithography machine lenses that meet the requirements.
Even if we want to buy it, we can’t buy it, even if we want to buy it through some small tricks, we can’t get it back, because this kind of lens is too big!
Palm-sized high-precision lenses, we can get them back through small means.
But in the face of a lens that is bigger than our gas stove cooking pot, how can our "staff" get back such arge lens, so the special lens problem required by the lithography machine is seriously stuck in our lithography. machine research! "
After a pause, Lin Xuan sighed deeply and said:
"And this kind of lens can''t be used even if you want to ship it back, because it is a specially designed lens!
Because we all know that when a magnifying ss zooms in or out, there will be imaging deviations. This imaging deviation is because our human brain can automatically analyze and make up for it.
So when we y with a magnifying ss, this imaging deviation does not affect our use of a magnifying ss, but for a machine that cannot automatically make up the brain, this imaging deviation is very fatal.
Especially for a lithography machine, if the lithography is slightly off, it will be fatal!
So why many expensive video cameras or camera lenses are so long, and why their lenses are more expensive than the camera itself.
In order to reduce imaging deviation, good cameras can only use multiple 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, due to different requirements, the structure of their lenses is also different, so the lens structure of 45nm and 120nm is also different.
So even if we get the lenses back from the outside using small tricks, we won''t be able to use them at all! "
The tens of thousands of viewers below heard Lin Xuan talk about the difficulty of the lithography machine lens. At this time, they realized that they were going to develop a lithography machine. Just a lens problem can block thending of the lithography machine!
