A school with the treasure of a town school can be regarded as a key school.

In order to cultivate students' interest in industrial science and technology, in order to better stimulate students' creativity. The Industrial Commission will issue a second-class special tool to each school in the key middle schools at the municipal level.

The second is Wang Mang's vernier caliper.

Unfortunately, this caliper was broken by Jiang Jiuling and two other friends. As for what is special about this caliper, Jiang Jiuling can't remember it very clearly.

Now Teacher He mysteriously took Jiang Jiuling to the third floor, he must have wanted to show off the "treasure of the town" of the school.

What will it be?

The third floor is paved with tiles, which are so clean that they can shine shadows, and shoe covers don't make a sound when stepped on.

Then Jiang Jiuling first saw a room with a [Multimedia Information Room] sign, probably because the stairs on the third floor had been locked independently, the wooden door of this multimedia information room was not locked.

Seeing Jiang Jiuling's curious expression, Teacher He thought of something, and then said smugly: "Have you ever seen an electronic computer?"

"Computer?" Jiang Jiuling nodded with a strange expression, "I've only heard of it and haven't seen it, our interest group has specially bought a lot of overseas magazines in order to study robot chariots." ”

"But I've seen a lot of references to it in magazines. ”

In '92, the word computer or computer was not unfamiliar to some young people.

The 90s was an era of rapid development of electronic information, whether it was magazines, newspapers, or television news, there were always computer-related news.

"Would you like to take a look?"

Teacher He's face was even more proud, and he used an almost show-off tone, "Although the computer is not the treasure of our No. 1 middle school, but this is an advanced computer that we bought with a huge amount of money. ”

Jiang Jiuling actually didn't want to see it, but he couldn't say it clearly.

Then Mr. He pushed the door open.

Sixteen brand-new wooden tables are visible above them, which are also partitioned, and some resemble the staff desks of later offices.

Sixteen off-white computers are neatly placed on the table, constantly exuding a bulky, backward atmosphere.

Looking at these computer models, it should be 286, and the computer host is still placed horizontally, which is for these computers, Jiang Jiuling may have seen them when he was a child, but only if he saw them.

When he first came into contact with the computer, it was already a Win95 system, and at this time, the 95 system did not even have a shadow.

Mr. He carefully turned on a computer and pressed the power button.

The boot screen is Windows 3.0, and it takes nearly a minute from boot to entering the interface.

"You're not going to use it, and you don't really understand what a computer can do. Teacher He pointed to the English interface with black and white as the main color on the screen and said: "But Jiang Jiuling, you have to remember that the future is the future of electronic informatization, and the traditional mechanical industry technology is vulnerable in the face of electronic informatization. ”

"At the beginning of the year, the United States disclosed a set of data, and I don't know if there is moisture in this data, but even if there is, it will not be too bad. ”

"What data?"

"Ninety-one years, they were newly recognized by the Holy Industrial Code. ”

Teacher He smiled bitterly and said, "This number is ten thousand and three thousand. ”

"The number of people recognized by the code of countries each year has always been a secret among secrets, but the fact that the United States dares to disclose it shows how confident they are. ”

"What a horrible number. ”

"There are more than 9,000 of them, which are the number of people who have already possessed the title and then successfully advanced, and the remaining more than 4,000 are newcomers who have been recognized by the legal code for the first time. ”

"What's more important, do you know?" Mr. He said to himself, "There are more than 10,000 people in total, half of whom have successfully obtained the recognition of the code by relying on electronic information technology. ”

"Ten thousand and three thousand......" Jiang Jiuling heard this number and fell into memory.

Jiang Jiuling is very familiar with patents, even if he has a certain understanding of foreign patent history.

In the 90s, the United States was indeed proud of the world in scientific and technological development, and the United States Patent Office called it a record year in 91. Because in this year, they issued nearly 110,000 patent certificates, which not only reached the highest number in the previous year, but also far exceeded the level of last year.

And more than half of the patents are related to electronic information technology.

Here it becomes 10,000 and 3,000, which does not mean that the United States in this time and space is weaker than the earth, on the contrary, it may be more powerful.

The sharp decline in numbers is only due to the fact that the Holy Industrial Code has rejected the applications for red rags, green rags, green rags, purple rags, etc., which are useless and repetitive.

Teacher He planned Jiang Jiuling recalled, "By the way, didn't you say that you had read a lot of overseas magazines before, so how is your English level?"

Jiang Jiuling's English is better than most Europeans and Americans, because ordinary Europeans and Americans can't understand those dazzling scientific and technological English terms.

Jiang Jiuling modestly said that it was okay, and he could barely read the English newspaper.

"Then you're going to have to learn more about computers in the future. Teacher He patted Jiang Jiuling on the shoulder, "Anyway, no one will use these computers here, I have a few English computer manuals here, I can't read them here, you take them back to study and study." ”

"Anyway, I'll take you to see the real baby. ”

......

The real treasure is placed in the fifth room of the hallway.

Not only are iron doors installed in this room, but even the windows are welded with thick steel bars.

To tell the truth, Jiang Jiuling is difficult to have any awe for the treasure of No. 1 Middle School, when he was in No. 2 Middle School before, Wang Mang-level calipers were directly used as tools by his companions, and finally broke it.

Now the first middle school is an iron door and an anti-theft window, which is inevitably a bit of a fuss.

Then Mr. He opened the iron cabinet in the middle and took out a wooden box from it, which was also printed with the words of the Suzhou Provincial Industrial Commission.

Waiting for Mr. He to solemnly open the wooden box, it turned out to be ...... inside

Is it a pair of glasses?

Jiang Jiuling took a closer look and found that it was not the ordinary kind of myopia glasses or sunshades.

Rather, it is a delicately shaped metal bracket with no lenses on it. But next to it, there are two more cylindrical magnifying eyepieces.

Is this a magnifying eyepiece?

Jiang Jiuling is not familiar with this kind of thing, but he is not unfamiliar with it either.

Some people who do precision machining or precision maintenance like to wear this. This kind of object is very ordinary, even a microscope table, and in the twenty-first century, a few thousand pieces of ordinary quality can be bought online.

Since it can be called a second-class special tool, and it is placed in a highly secure room, Jiang Jiuling certainly does not think that it is just an ordinary magnifying eyepiece.

So Jiang Jiuling was silent and waited for Teacher He's explanation.

Teacher He's explanation was very simple, he took out the eyepiece frame and put the silver-white eyepiece on, and then handed it to Jiang Jiuling and motioned for it to be brought.

The eyepiece was engraved with the magnification mark of X8, and with the eyepiece, Jiang Jiuling took a closer look at his hands.

Under the eyepiece, the delicate palm prints on the hands can be clearly observed.

But this can't be considered special, some watchmakers can achieve this effect with the kind of eyepiece they wear.

"It's insight glasses, and you try to look at this piece of metal with glasses. Teacher He knew what Jiang Jiuling was wondering about, so he took out a string of metal iron pieces similar to keys from the cabinet.

These patches are all around 0.5 mm thick and come in different shades.

Teacher He put a copper piece on Jiang Jiuling's hand and motioned him to stare at the copper sheet carefully.

Jiang Jiuling did as he heard what he said, and then an incredible scene happened. Under Jiang Jiuling's gaze, this magnified copper piece gradually turned into a glass-like substance.

It became transparent, and in the end, only a thin outline was left in Jiang Jiuling's field of vision.

Through this outline, Jiang Jiuling could clearly see the palm print hidden under the copper plate.

"This ...... Is this a perspective function?" Jiang Jiuling touched the copper sheet with his other hand in disbelief.

The copper sheet is still there, the tentacles are cold, and the metal object is 100%.

Even if he had seen Director Zhang Yuanwen operate the two steel balls out of thin air, he was not as shocking as the glasses in front of him that brought Jiang Jiuling.

On the one hand, it is someone else's ability to operate the iron ball after all, and on the other hand, that ability, without this insight glasses, makes Jiang Jiuling think about it.

It's a plug-in!

How is this thing made?

Jiang Jiuling also liked to read some novels when he was in school, and he wanted to take these glasses to play some gambling jade and guess the dice, wouldn't it be extremely easy for the other party to guess bankruptcy?
