Monster Factory - Chapter 396

Chapter 396

“Discoloration card?”

“Three-dimensional stereograph painting?”

The accompanying students first thought about the kind of card toys that they saw at different angles and saw different pictures when they were young . But soon this conjecture was overturned . The font on the iron ruler was not flat at all . Instead, it was dug into the iron ruler, and they could clearly see the traces of the dent .

"Forever Friendship," Professor Kobayashi's eyes were like the helpless firewood in the fire .

There was nothing unusual in the front view, he could only see the font from another angle: "What does this mean? It shows that the four characters on the iron ruler are unimaginably horizontal and vertical .

Its principle is very simple to explain . If a piece of paper is as thin as a wing of the cicada and its sides horizontal and perpendicular to the gaze, then it can easily disappear . Similarly, the bottom of the font that is recessed on the iron ruler should be as rough as the surface . This effect can be achieved by processing straight lines with terrifying accuracy on the side . The explanation is simple, but it is very difficult to do .

In the live broadcast room, after the popularization of science by knowledgeable mechanical talents, the students brushed sixty-six in the bullet screen . . .

"Haha~ Just now, the Japan Institute of Technology was determined that there was nothing, so it was slapped at another angle . "

"It's so cool, just look at this visual effect, and you can compare that nut . The thread isn't invisible, but the thread is as thin as the silk . And our four words are as big as mahjong, and the difficulty is natural . It's much higher . "

"Is this the only thing, student?" Kobayashi lose a word, let the bullet screen and the students below suddenly quiet: "Great ideas, admirable machining accuracy . But in our opinion, the industrial level represented by this gift is still a bit short of the top manufacturing technology . "

It was not arrogance . The technology demonstrated by this iron rule, Professor Kobayashi could also manufacture it using the famous national factory of high-precision instruments . Of course, there were difficulties, and it would take much time, but it was not difficult for him .

"It's over, looking at this guy's confident look as if he can also make this kind of magical lettering . "

"After all, their precision machining technology is the best in the world, and they can't help but be excused . "

"Ah~ Although it is not difficult, it is not a loss . "

Discussions resumed in the live broadcast room .

"Professor Kobayashi, I think you misunderstood me . " Ye Qing raised the iron ruler in his hand and turned the other side around .

"In the beginning, you gave us a nut and let us process a screw . Then naturally, we should repay our efforts and present a complete commemorative gift that requires the cooperation of our two schools . "

After a pause, Ye Qing was satisfied with the deflated expression on the opposite side . After showing the iron ruler in different angles and confirming there were no Chinese characters on the opposite side of the iron ruler, Ye Qing's eyes became calm: "The long friendship is a blessing we send to your school . I want to invite your school to write another sentence in your language on the opposite side of this iron ruler to prove our friendship . "

"Engrave a sentence?" Kobayashi did not respond a little: "What is this sentence?"

"The answer to what has already been written on the iron ruler, just interpret it, then use your text to engrave it . "

After talking, Ye Qing handed this iron ruler to Professor Kobayashi .

The camera clearly captured the suspicious ghost on Kobayashi's face, and the moment he took the iron ruler, his right hand sank obviously, revealing why he was so heavy .

The students of Japanese science and technology came around with a crash . The highlight is here, it turns out that this iron ruler not only has amazing precision machining technology but also hides a puzzle to solve it . Fortunately, the Japanese University of Science and Technology had already made preparations here .  

At noon, Professor Cai informed them that they would give away an iron ruler as a gift . They kept guessing this iron ruler would be troublesome . Therefore, many of the town's instruments that needed to be packed into shockproof metal boxes and packed away were also taken to the multimedia center .

The iron ruler was more than thirty centimeters long, and even the scale was not marked on it . Kobayashi believed that even if there was a mystery, he could easily crack it . This confidence came from the equipment they carried .

A Nikon s 1500 industrial electronic digital microscope was moved to the desk by students from the Japanese University of Science and Technology .

Nikon is one of the world's top optical lens factories . The microscope they took out was the one with the highest effective magnification among the current optical microscopes, and none of them compete . Hum~ Anything, that is so greasy, is nowhere to be hidden under this top optical microscope .

However, when the students of the Japan University of Technology set up the microscope and turned their gaze to the liquid crystal display on the microscope . Their reaction was more exaggerated than the detonation of a grenade . With a snap, they took a step back .

"This is impossible!" Kobayashi yelled in his native language: "Why is its surface flat?"

Other students said probably damn expressions . Because when they just adjusted the magnification to the best observation multiple of 1,200 times, they actually saw the surface of this iron ruler, and it was still smooth . Although it was not as flat as a mirror, it was close to ordinary steel with the naked eye, and its surface was almost the same .

To study metal, the first step is to study its characterization . At a magnification of 1,200 times, you can directly see the microstructure of the metal surface, like the metal, like snow-like martensite and austenite .

In the same way, they observed the iron ruler with their naked eyes and found no greasiness . They naturally thought they were hidden under a microscopic mechanism that was invisible to the naked eye .

"What did they see?"

If we say the previous lettering . For them, it could be called a difficult level of processing technology . The smooth characterization of this iron ruler was equivalent to the fear level processing technology .

It took many old energies to suppress the fear in their hearts and continue to study this iron ruler .

Time passed little by little, and here at the Japan University of Technology side, they had already flown to Siberia for a long time with their pride which had been changing to dignity and madness . Because they couldn't find anything, no matter what way they would observe . The surface of this iron ruler was all flat, let alone a greasy puzzle, even a non-black stain is unfound .

"Haha~ You see how they are tangled . "

"I'm embarrassed . Let them look down upon us and give a try again . "

"I think . . . they need Detective Conan to save the scene!"

After half an hour passed, Kobayashi raised his head with difficulty, and his face was covered with sweat beads: After . . . After our unanimous study, there seems to be no mystery on this iron ruler . "

"Yes . " Ye Qing replied unhurriedly, making the students of the Japan Institute of Technology almost uncomfortable .

"Have you measured the length of this iron ruler?"

"Yes . . . I have measured it . " Kobayashi took out a handheld rangefinder: "This is a rangefinder produced by our Nikon company . We have measured not only the length but also the width and height . "

"Its length is 0 . 32569 meter . "

"The length of the ruler is long, and the answer lies in its length . " Ye Qing stood up and shook his head: "The accuracy of the rangefinder is not enough . You need to change to a more advanced instrument to re-measure its length . "

"But we have reached the accuracy of Sim, its length is too long to measure with a micrometer . If you want more accuracy, you need to use a laser interferometer . "

"To what level can your laser interferometer be accurate?"

"Nano level . " 

Kobayashi's voice gave a hint of a roar: "We can be accurate to 2 nanometers, but what's the point of measuring this iron ruler?"

"The accuracy of two billionths of a meter is unmachined at this stage . Even our industrial mother machine can only determine the accuracy of metal materials at 50 nanometers . "

"0 . 32569 meters?" Ye Qing said with a serious look .

"What do you mean? We measured this length . "

"There are 734 behind . " Ye Qing looked at him and reported a number .

Kobayashi didn't believe in the authenticity: "Have you made precision to 0 . 1 silk?"

"Since your laser jammer does not meet the accuracy standard, then I will tell you the accurate answer . "

Ye Qing said quietly: "We have fixed the accuracy to one-half nanometer, which is the accuracy of 5 parts per billion . "

"The ruler energy is long . "

"If you are in a vacuum box, use a more advanced jammer to measure the length of this iron ruler . "

"You will get such a set of numbers 0 . 32569734830 a very simple set of decimal numbers, as long as you replace this set of numbers with your text in decimal, you can get the words you want to engrave on . "

There was a tomb silence . The old man of time dropped a time bomb in the multimedia center, allowing for their expression to freeze instantly .

Convert the length of the ruler to their text? Is it concluded that?

What words are they going to engrave?
