Discoloration card?

Stereoscopic lenticular painting?

The first thing the students below think of is the kind of card toy that can see different pictures from different angles when they were young.

But this conjecture was quickly overturned, and the font on that iron ruler was not flat at all. Rather, it was cut into the iron ruler forcibly, and the traces of the depression could be clearly seen.

“Friendship…” Professor Kobayashi’s eyes were like firewood burning helplessly in the fire.

There is no abnormality in the front view, and the font can be seen from another angle.

What does this show?

It shows that the four characters on the iron ruler, between the strokes and strokes, are unimaginable horizontal and vertical.

Its principle is very simple to explain. If a piece of paper is as thin as a cicada wing, the side is horizontal and perpendicular to the eyes, then it will easily disappear.

Similarly, the bottom of the font that is sunken on the iron ruler, as long as it maintains the same roughness as the surface. This effect can be achieved by machining a straight line with a terrifying precision on the side.

It’s easy to explain, but very difficult to do.

In the live broadcast room, after being popularized by knowledgeable mechanical experts, the students spontaneously rushed through the barrage…

“Haha~ I just insisted on the Nikkei side that there was nothing, but I was beaten in the face from a different angle.”

“It’s so cool. Just use this visual effect to compare that nut. Isn’t they invisible to the thread, but the thread is as thin as silk. And our four characters are as big as mahjong, and the difficulty is natural. It’s going to be much higher.”

“Is it the only way, this classmate?” Kobayashi said loosely, making the barrage and the students below suddenly quiet.

“Great ideas, admirable machining accuracy.”

“But in our opinion, the industrial level represented by this gift is a little bit short of the top manufacturing technology.”

It’s not arrogant, the technology demonstrated by this iron ruler, Professor Kobayashi, can also be manufactured by borrowing from a well-known domestic high-precision instrument factory.

Of course there is difficulty, and it will take a lot of time, but he can’t be troubled.

“It’s over, look at this guy’s self-confident look, it seems that they can also make lettering with this magical effect.”

“After all, they are the world’s first in precision machining technology. It is not difficult for them, and it is understandable.”

“Hey~ Although it’s not difficult, it’s not a loss.”

In the live broadcast room, the discussion resumed.

“Professor Xiaolinjing, I think you have misunderstood what I mean.” Ye Qing raised the iron ruler in Yang’s hand and turned the other side around.

“At the beginning, you gave a nut and let us process a screw.”

“Then we naturally have to retaliate, and present a complete commemorative gift that requires the cooperation of our two schools.”

After a pause, Ye Qing was very satisfied with the shriveled expressions of the guys opposite.

After showing the iron ruler from different angles, and after confirming that there is no Chinese character on the reverse side of the iron ruler, Ye Qing’s eyes calmly said: “The long friendship is a blessing from us to your school.”

“I would like to ask your school to engrave another sentence in your language on the reverse side of this iron ruler to verify our friendship.”

“Engrave a sentence?” Xiao Linjing didn’t react. “What’s a sentence?”

“What to engrave, the answer is already written on the iron ruler, you only need to interpret it, and then use your words to engrave it.”

After speaking, Ye Qing handed the iron ruler to Xiaolinjing.

The camera clearly captured the skepticism on Kobayashi’s face, and the moment he took the iron ruler with him, his right hand obviously sank down, showing why it was so heavy.

The students of Nikkei rushed over.

The highlight is coming. It turns out that this iron ruler not only has amazing precision processing technology, but also hides a mystery for them to solve.

Fortunately, the Japanese University of Science and Technology had already prepared. At noon, Professor Cai informed them that they would give an iron ruler as a gift. They kept speculating about what would be tricky about this iron ruler.

So many of the town’s instruments that had to be packed in a shock-proof metal box and taken away were also taken to the multimedia center by them.

The iron ruler is more than 30 centimeters long, and there is no marking on it. Kobayashi and the others believe that even if there is a mystery, they can easily solve it.

This confidence comes from the equipment they carry.

A Nikon S1500 industrial electronic digital microscope was moved to the table by the students of Nikon.

Nikon is one of the top optical lens factories in the world. The microscope they took out is the one with the highest effective magnification among the current optical microscopes.

Humph~Anything tricky, under this top optical microscope, there is nowhere to hide.

However, when the students at the University of Science and Technology set up their microscopes, they turned their attention to the LCD monitors on the microscopes.

Their reaction was more exaggerated than detonating a grenade.

Swish, they took a step back.

“It’s impossible!” Kobayashi yelled in his mother tongue: “Why is its surface flat?”

Most of the other students are also living with ghost expressions.

Because when they just adjusted the magnification to the best observation magnification of one thousand two hundred times, they saw that the surface of the iron ruler was still smooth. Although it is not as flat as a mirror, it is similar to the surface of ordinary steel when it is directly approached with the naked eye.

To study metal, the first step is to study its characterization.

Magnified one thousand two hundred times, you can directly see the microstructure of the metal surface, such as the martensite and austenite like snowflakes on the metal.

Similarly, when they observed the iron ruler with naked eyes, they did not find any tricks, and naturally thought it was hidden under a microscopic mechanism that was invisible to the naked eye.

What did they see in the end?

If you talk about the previous lettering, for them, it can be called a difficult-level processing technology. The smooth representation of this iron ruler is equivalent to fear-level processing technology.

It took a lot of hard work before they suppressed the fear in their hearts and continued to study the iron ruler.

Time passed by little by little. On the side of the Japanese University of Science and Technology, I had already flown to Siberia with pride, and changed into dignity and madness.

Because they can’t find anything, no matter how they observe it. The surface of this iron ruler is completely flat, not to mention the tricky puzzles, even a stain that is not black can be found.

“Haha~ Look at the way they are tangled.”

“I’m stumped, let them look down upon us and try again?”

“I think… they need Detective Conan to save the scene!”

Time has passed for half an hour, Kobayashi raised his head with difficulty, with sweat beads on his face: “After… after our unanimous research, there seems to be no mystery on this iron ruler.”

“Yes.” Ye Qing replied unhurriedly, making the group of Japanese Polytechnic students almost unhappy.

“Have you measured the length of this iron ruler?”

“Yes… have been tested.” 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 meters.”

“The ruler has a long energy, and the answer lies in its length.” Ye Qing stood up and shook his head: “The accuracy of the rangefinder is not enough. You can change to a more advanced instrument to measure its length again.”

“But we have been accurate to the silk meter. Its length is too long to be measured by a micrometer. If you want more accuracy, you must use a laser interferometer.”

“How accurate can your laser interferometer be?”

“Nano-level.” Kobayashi’s voice was accompanied by 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 not processed by machine tools at this stage. Even our industrial master machine can only determine the accuracy of metal materials at 50 nanometers.”

“0.32569 meters?” Ye Qing said a number with serious eyes.

“What do you mean? We measured this length.”

“There is still 734 behind.” Ye Qing looked at him and reported a number.

Kobayashi was a little disbelieved and said, “Did you make the precision accurate to 0.1 silk?”

“Since your laser jammer does not meet the accuracy standards, then I will tell you the exact answer.”

Ye Qing said calmly: “We fixed the accuracy at one-half nanometer, which is an accuracy of five ten billionths of a meter.”

“The ruler has a long energy.”

“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 characters in decimal, you can get the words you want to engrave on it.”

quiet.

The old man of time dropped the time bomb in the multimedia center, making their expressions freeze instantly.

Convert the length of the ruler into their text?

inferred……

What characters do they want to engrave?
