The back of the board receives the sound wave, then its "diffuse reflection" principle will also dissipate this sound wave, and will emit a sound wave with the same frequency on the front of the board.

In other words, this kind of sound wave diffuse reflection coating can effectively avoid being detected by sonar, so that the object coated by the coating can achieve a feeling of "disappearing out of thin air".

Although the working principle of this coating is complex, it is essentially a means of concealment.

It's just that it doesn't absorb all the sound like sound-dampening metal, but while absorbing the sound, it generates sound waves on the back, hits obstacles, and launches them through the front.

It is similar to the so-called "optical stealth", that is, the optical stealth module mounted on the third-generation steel armor and the optical stealth drone array.

Optical stealth is to distort the specific angle of photons through the refraction of light, so that visible light cannot reach it, so as to achieve stealth at the optical level.

The same is true for sonic diffuse plating.

The existence of this plating also makes it possible to hide underwater, and if the shell of the submarine can be painted with a layer of this thing, then the sonar will not be detectable at all.

No matter how much sound waves are emitted at the plating, the same sound waves are emitted from the back side and reflected back through the front side intact.

The sound waves that were shot out did not reach the corresponding object at all, but hit the seabed directly, so that the object could be identified as a ghost.

The submarine is painted with this sonic diffuse metal, then the submarine will truly become the so-called "night assassin", and the prestige of the submarine will soar in history.

At that time, the detection means of submarines by various countries will no longer be sonar.

Rather, it is a magnetic anomaly detector (a change in the magnetic field caused by the interference of the metal hull with the earth's magnetic field), an infrared thermometer (a thermal detector that emits heat from a submarine to heat the surrounding seawater, causing the temperature of the sea water to rise), radar (detects periscopes and snorkels that are exposed to the water), wake anomaly detection, and even the use of biological detection methods (dolphins).

In any case, the sound wave diffuse reflection plating that Ye Fan exchanged for today will definitely rewrite the pattern of today's naval warfare.

Of course, the technology taken out must be gradual, otherwise this kind of black technology that others look directly like "Zenith Star Man" will have ghosts if they are not suspected.

Now that Datang Technology has risen, it needs more time to stabilize and establish a correct image in front of the people of the country.

Finally, it is necessary to adopt a specific plan, and after phasing out the labor force in the factory, it will take on the role of ensuring the livelihood of the eliminated population, that is, "supporting" them.

When you have millions of people under your command, then you are truly invincible.

When your living habits are completely linked to a company, and even the living security comes from it, then the last thing you want to happen to the company is often the vested interests, but this vested interest may be millions of people.

At that time, if these technologies are taken out, even if some people will suspect it, even if someone has a bad intention, they will definitely not dare to act rashly.

What Datang Technology has to do now is wait.

Tenglong Chip Group needs time to upgrade the lithography machine from 22nm to 7nm, so as to completely replace the position of chip foundries such as TSMC.

Datang Heavy Industries also needs a certain amount of time to complete industrial upgrading, completely eliminate manual labor, and replace all production lines with intelligent robots, which is also a matter of waiting. 90 Literature Network

Even with Ye Fan's technology, it will take a certain amount of time to spin off a department from Datang Heavy Industry to establish a Datang Arms Company and sell high-tech arms, which depends on Ye Fan's ability to control Baidao.

In any case, Datang Technology is not short of money now, what is lacking is time.

"Origin, when the time comes, you order the production line of Datang Heavy Industries to produce a new coating according to the material I said, and after it is produced, it will be coated on the submarine cable.

And all the underwater submarines and robots involved in the construction, this project is a bit huge, in terms of funds, I will allocate another 10 billion to you, although the materials are a bit expensive, but they are enough. Ye Fan was inside the steel armor and said to the origin.

"Okay master, I will arrange for Chairman Lin Wei to go to major mineral companies to purchase raw materials, but the master you said this plating,

In essence, it is still a relatively reactive metal, and it will spontaneously combust when it encounters water, so it is necessary to add another layer of waterproof coating, which will increase the budget by an additional 20%. ”

Soon, after some analysis, the origin opened his mouth and said to Ye Fan.

"Okay, allocate another 2 billion to you, if it's not enough, you can continue to look for me." Ye Fan also waved his hand and directly agreed.

After all, no matter how much you don't have to save money on security, who knows what will happen if you don't do a good job in security measures?

Ye Fan took this underwater submarine and cruised all the way to the underwater base in the South China Sea, at this time, because it was already night, the bottom of the sea was already out of sight.

Except for some deep-sea fish with their own light sources, which look like fireflies in the dark night, this deep sea is completely silent.

Strange shapes, all kinds of fish, and some amazing-looking underwater creatures, at the beginning, they also constantly refreshed Ye Fan's worldview.

Under the guidance of the origin, Ye Fan walked out of the submarine, started the ion engine, and flew towards the tunnel into the sea, intending to return directly to Datang Heavy Industry and end the day's work.

In any case, after Datang Heavy Industries invested 100 billion yuan in upgrading, its equipment and industrial machine tools have also begun to be upgraded.

Whether it is the production of steel armor, or the production of liquid metal, or the production of holographic projection modules, it is also increasing.

At the same time, a lot of space has been reserved for other technologies and other equipment to be put into production.

Now 100 billion funds, in the transformation of less than 7 billion, has already had such fruitful results, if the 100 billion is smashed down, what will Datang Heavy Industry become?

This also aroused Ye Fan's curiosity.

What Ye Fan needs now is time, just one word, wait.

......

On the other side of the ocean, the Supreme Command of Amejian.

A white man slammed his fist on the table.

"Fack! How could they be in the Bermuda Triangle! How could it suddenly sink! Check it out for me! Be sure to check it out! The commander said with a gloomy look on his face, very angry.
