Color change card?

Stereo raster painting?

The following students first thought of the kind of card toy that they could play at different angles and see different pictures.

But soon this conjecture was overthrown, and the font on the iron ruler was not flat at all. Instead, it is hard to dig into the iron ruler, and you can clearly see the traces of the depression.

"Friends... Friendship" Professor Xiao Linjing’s eyes are like the firewood that is helpless in the fire.

There is no abnormality on the front side, and you can see the font at an angle.

What does this mean?

Explain the four words on the iron ruler. Between the characterizations, it is unimaginable horizontal and vertical.

Its principle is simple to explain. If a piece of paper is as thin as a flap, the side is horizontally perpendicular to the eye, then it is easy to disappear.

Similarly, the bottom of the font that is recessed on the iron ruler has the same roughness as the surface. This can be achieved by machining a straight line that is horrifying to the side.

It's easy to explain, but it's very difficult to do.

In the live broadcast room, after the knowledgeable mechanical master science popularization, the students invariably brushed the six six six six in the barrage...

"Haha~ Just over the day of the science and technology work, I still insisted that there was nothing, and I was beaten at a different angle."

"It’s so cool, just take this visual effect and you can compare that nut. They are not thread-invisible, they can be threaded as thin as silk. And these four words are as big as mahjong, and naturally difficult. It must be a lot higher."

"The only way, this classmate?" Xiaolin Jing's words made the barrage and the students below suddenly quiet.

“Great ideas, admirable machining accuracy.”

“But in our opinion, this gift, the level of industry represented, is a little worse than the top manufacturing technology.”

It is not arrogant. The technology exhibited by this iron ruler, Professor Xiao Linjing, can also be manufactured by borrowing a well-known high-precision instrument factory in China.

Of course, there is a lot of difficulty, and it will take a lot of time, but it will not be difficult for him.

"When it's over, look at this guy's confident look, as if they can also make such a magical lettering."

"After all, they are the world's number one in precision machining technology, and they can't help but be excusable."

"Hey~ Although it is not difficult to live, it is not lost."

In the live broadcast room, the discussion resumed.

"Professor Xiao Linjing, I think you misunderstood what I meant." Ye Qingyang took Yang’s iron ruler and turned the other side.

"In the beginning, you presented a nut and let us machine a screw."

"Then we naturally have to reciprocate and give away a commemorative gift that requires our two schools to work together to be a complete commemorative gift."

After a pause, Ye Qing was very satisfied with the expression of the guys on the opposite side.

Show the iron ruler at different angles and confirm the opposite side of the iron ruler. After there is no Chinese character, Ye Qing’s eyes are calm and unrestrained: “The long friendship is a blessing we gave to your school.”

"I want to ask your school, in the opposite side of this iron ruler, in your language, engrave another sentence to prove our friendship."

"Engrave a word?" Xiaolinjing did not respond: "What is the word?"

"What is engraved, the answer has been written on the iron ruler, you only need to interpret it, then use your words and engrave it."

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

The camera clearly captured the suspicious face on Xiaolin's face, and when he took the iron ruler, his right hand clearly sank, revealing why it would be such a heavy expression.

The students of the Japanese Polytechnics screamed around.

The highlight is coming. It turns out that this iron ruler not only has amazing precision machining technology, but also hides a puzzle to crack them.

Fortunately, there is preparation for the Japanese Polytechnic University. At noon, Professor Cai informed them that they would give a iron ruler as a gift. They are constantly speculating that this iron ruler will be a bit tricky.

Therefore, many of the township instruments that had to be packed in the shockproof metal box and packed and taken away were brought to the multimedia center.

The iron ruler is also more than 30 centimeters long, and the scales are not marked on the top. Kobayashi believes that even if there is a mystery, they can easily crack it.

This self-confidence stems from the equipment they carry.

A Nikon s1500 industrial electronic digital microscope was moved to the table by Japanese students.

Nikon is one of the world's top optical lens factories. The microscope they took out is currently one of the most efficient microscopes in optical microscopes.

哼哼~ Any greasy, under this top optical microscope, there is nowhere to hide.

However, the students of the Polytechnic University of Japan, when they set up the microscope and turned their attention to the liquid crystal display on the microscope.

Their reaction is more exaggerated than the detonation of a grenade.

Awkwardly, they took a step back.

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

Other students are also alive and well.

Because they just adjusted the magnification to the best observation multiple of 1200 times, the surface of the iron ruler was still smooth. Although it is not as flat as a mirror, it is directly close to ordinary steel with the naked eye, and its surface is similar.

The first step in studying metal is to study its characterization.

Magnified 1200 times, you can directly see the microstructure of the metal surface, such as martensite and austenite on the metal, like snowflakes.

Similarly, they observed the iron rule with the naked eye, and found no greasy, naturally believed to be hidden under the microscope that is invisible to the naked eye.

What did they see?

If you say the previous lettering, for them, it is called difficult level processing technology. The smooth representation of this iron ruler is equivalent to the fear level processing technique.

After spending a lot of effort, they suppressed the fear in their hearts and continued to study this iron ruler.

Time passed by little by little, on the side of the University of Science and Technology, before the smug had already flown to Siberia, replaced with dignity and madness.

Because they can't find anything, no matter what way they look. The surface of this iron ruler is all flat, not to mention the tricky puzzle, even a stain that is not black can not be found.

"Haha~ you see what they are tangled."

"I was stumped, let them take a nap and let us try it?"

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

After half an hour has passed, Kobayashi has raised his head in a difficult way, and his face is full of sweat: "After our unanimous research, there seems to be no mystery on this iron ruler."

"Yes." Ye Qing did not answer slowly, so that the students of the Japanese Polytechnics were so painful that they would not be born.

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

"There are...tested." Xiaolinjing took out a handheld range finder: "This is the rangefinder we produced by Nikon. Not only the length, but also the width and height we have measured."

"It is 0.32569 meters in length."

"The ruler is long, and the answer is on its length." Ye Qing stood up and shook his head: "The accuracy of the rangefinder is not enough. You can change the length of the instrument by re-measuring its length."

"But we have been accurate to the silk meter, its length is too long, the micrometer can not be measured. To be more precise, then use a laser interferometer."

“Which level can your laser interferometer be accurate to?”

"Nano-scale." Kobayashi's voice has a snarl: "We can be accurate to 2 nanometers, but what is the significance of measuring this iron ruler?"

“The accuracy of two-billionths of a meter is not machined at all at this stage. Even our industrial machine can only determine the accuracy of metal materials at 50 nanometers.”

"0.32569 meters?" Ye Qing said with a serious figure.

"What do you mean? This length is what we measured."

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

Xiaolinjing does not believe in authenticity: "Do you accurately measure the accuracy to 0.1?"

"Since your laser jammers don't meet the accuracy standards, then I will tell you the exact answer."

Ye Qing said calmly: "We have fixed the accuracy on one-half nanometers, which is the precision of five meters per billion."

"The ruler is long."

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

"There will be a set of numbers 0.32569734830, a very simple set of decimal numbers. Just replace this set of numbers with your decimal text and you will get the words you want to engrave on it."

Quiet.

In the multimedia center, the old man left the time bomb and let their expressions freeze instantly.

Convert the length of the ruler into their text?

inferred……

What words do they want to engrave? (To be continued., your support is my biggest motivation.) 16-11-1502:37:58
