A discoloration card?

3D grating?

The first thing that comes to mind for the next students is that when they were kids, they played with a card toy that saw different images from different angles.

But very soon, this conjecture was overturned, and the font on the iron ruler, it was not even planar. Instead, it is raw and carved into the iron ruler, so that the marks of the depression can be clearly seen.

Professor Kobayashi looked at Professor Kobayashi as if he was burning wood in a blazing fire.

There are no abnormalities in the front view, you can see the font at another angle.

What does that mean?

It is hard to imagine horizontal verticality between the four words on that iron ruler, one by one engraving.

Its original interpretation is simple: if a piece of paper as thin as a cicada's wing is horizontally perpendicular to the eye, it can easily disappear.

Likewise, the bottom of the indented font on the iron ruler as long as it remains as rough as the surface. This effect can be achieved by side-processing lines that are precise enough to be horrific.

Simple to explain, but very difficult to do.

In the live broadcast room, after knowledgeable mechanical expert Kopp, students brushed six, six, six in the barrage...

“Ha ha ~ Just now, Nippon Technologies had bitten at nothing, and he was hit in the face at another angle. ”

“It's awesome, just for this visual effect, you can compare that nut. They are invisible threads, but they are as thin as silk. And our four words, as big as mahjong, are naturally much more difficult. ”

“Is that all, this classmate?” Kobayashi loosened a sentence to make the barrage and the students below suddenly quiet.

“Great idea and admirable processing accuracy. ”

“But in our view, this is a gift, the level of industry represented, a little short of the best manufacturing technology. ”

Not arrogant, this iron ruler demonstrates the technology, Professor Kobayashi, borrowing a well-known high-precision instrument factory in Japan, can also be manufactured.

Of course it's difficult. It takes a lot of time, but it's hard not to beat him.

“It's over, look at this guy confidently, as if they could also make this magical effect engraving. ”

“After all, they are the number one in the world in precision processing technology, and there are reasons why they can't be helped. ”

“Alas, it's not difficult, but it's not a loss. ”

Discussions resumed in the live broadcast room.

“Professor Kobayashi, I think you misunderstood what I meant.” Ye Qingyang lifted the iron ruler in Yang's hand and turned the other side.

“You gave us a nut and let us make a screw. ”

“Then naturally we will have to return the favor and give a souvenir gift that requires our two schools to work together. ”

Paused for a moment, Ye Qing was very satisfied with the look on the face of those guys across the street.

After showing the iron ruler at different angles and confirming the reverse side of the iron ruler without any Chinese characters, Ye Qing's gaze was not compelled: “Friendship for a long time is a blessing we sent to your school. ”

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

“Carve a sentence?” Kobayashi didn't react: “engrave what? ”

“What is engraved, the answer is written on the iron ruler, all you have to do is read it, and then engrave it in your words. ”

After that, Ye Qing handed this iron ruler to Xiaolin Jing.

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

The students of J.T. raved around.

So this iron ruler not only possesses amazing precision machining technology, but also conceals a mystery to solve.

Fortunately, they were prepared at the Japan Polytechnic University, and Professor Cai informed them at noon that an iron ruler would be given as a gift. They just keep guessing what this iron ruler will get tired of.

So they had to put it in a shockproof metal box, pack up a lot of the town equipment, and they took it to the multimedia center.

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

This confidence comes from the equipment they carry.

A Nikon S1500 Industrial Electronics Digital Microscope was moved to the table by JT students.

Nikon, one of the world's top optical lens factories. The microscope they took out was one of the highest effective magnification microscopes in the current optical microscope.

Humph ~ Any cat is tired, there is nowhere to hide under this top-of-the-line optical microscope.

Yet when students at the University of Science and Technology set up microscopes and turned their eyes to the LCD monitors on the microscopes.

Their reaction was more exaggerated than detonating a grenade.

Pull back, they take a step back.

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

Other students, mostly also live with ghostly expressions.

Because when they had just adjusted the magnification to the optimal observation multiplier of a thousand or two hundred times, they actually saw the surface of this iron ruler and it was still smooth. Although not as flat as a mirror, it is similar to the naked eye's direct proximity to ordinary steel, observing its surface.

To study metals, the first step is to study their characterization.

One thousand and two hundred times larger, you can see directly the microstructure of the metal surface, like the top of the metal, like the snowflake of the marzipan and the austenitic body.

Likewise, they looked at this iron ruler with their own eyes and found no cat fatigue, naturally thought to be hidden under microscopic institutions invisible to the naked eye.

And what did they see?

If you say the previous engraving, it is a difficult processing technique for them. The smooth characterization of this iron ruler is equivalent to fear-grade processing technology.

It took the boss a lot of effort to suppress the fear in their hearts and continue to study this iron ruler.

Time passes at 1: 00, on the side of the University of Science and Technology, before flying to Siberia with pride, swapping weights, going crazy.

Because they can't find anything, no matter how they look at it. The surface of this iron ruler, all in one horse, Hirakawa, let alone the cat puzzle, can't even find a color spot that is not black.

“Ha ha ha ha ha ha ha ha ha ha ha ha ha ha ha ha ha ha ha ha ha ha ha ha ha ha! ”

“We're stuck, let them take another look. Let's try? ”

“I think... they need Detective Conan to come to the rescue! ”

Time went on for half an hour, Kobayashi raised his head with difficulty, and his face was full of sweat beads: "… After our unanimous study, there seemed to be no mystery on this iron ruler. ”

“Yes.” Ye Qing replied slowly, leaving the students of Nippon Science and Technology in a hurtful state.

“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, not only in length, but also in width and height. ”

“It is 0.32569 meters long. ”

“The ruler has a long energy, and the answer lies in its length.” Ye Qing stood up and shook his head: “The rangefinder is not accurate enough, you can replace the advanced instrument to re-measure its length. ”

“But we have reached the precision of the silk, which is too long to be measured in thousands of feet. To be more precise, use a laser interferometer. ”

“To what level can your laser interferometer be precise? ”

“Nano-grade.” Kobayashi's voice bore a slight roar: “We can reach exactly 2 nm, but what's the point of measuring this iron ruler? ”

“Two-billionths of a meter of precision, there is no machining at this stage. Even our industrial mother machine can only determine the precision of the metal material at 50 nanometers. ”

“0.32569 meters?” Ye Qing seriously said a number.

“What do you mean? This length, we measured. ”

“There are 734 left.” Ye Qing looked at him and reported a number.

Kobayashi had some disbelief in the tunnel: “Did you get the precision to 0.1 silk? ”

“Since your laser jammer doesn't meet the accuracy standards, I'll tell you the exact answer. ”

Ye Qing said calmly: “We set the accuracy at one-half nanometer, that is, five hundred billion meters of accuracy. ”

“Ruler energy length. ”

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

“One would come up with such a set of numbers, 0.32569734830, a very simple set of decimal numbers, and by replacing this set of numbers with decimal numbers, you would come up with the words you want to engrave on them. ”

Jing.

Time old people drop time bombs in multimedia centers to instantly define their faces.

Convert ruler length to their text?

to…

The words they're engraving?
