Just after the 11th National Day holiday, Zhou Yu came to the Materials Research Institute.

The Institute of Materials has recently taken the lead, with 7 successful breakthroughs in 7 projects, most of which are still systematic projects.

Zhou Yu first came to the bionic laboratory under the Institute of Materials, which is a laboratory specializing in the development of bionic materials.

Many of the animals and plants in the natural world contain rich natural scientific truths.

Darwin's theory of evolution proposes natural selection for the survival of the fittest, and evolutionary imperfect organisms cannot pass on their genes in a complex competitive environment.

Midoqi, the director of the materials laboratory, knew that Zhou Yu had come to the laboratory he was in charge of, and immediately put down his work and came out.

"Hello Mr. Zhou, I am Midoqi, the director of the bionic laboratory. It is our honor for you to come to our laboratory, please tell us if you have any guidance. ”

Zhou Yu looked at the appearance of Ai Ai in the Midoqi period, he waved his hand and said, "Don't be too nervous, I'm not a flood beast, what is there to be afraid of."

Feng Yunde didn't come with me this time, because he had important work to deal with.

I came to your lab to learn about the bionic fish gills that you declared a few days ago, and I am very curious about this product. ”

The Institute of Materials has declared a series of projects to develop the ocean, which is one of the blue ocean projects of the scientific research center, and the blue ocean project is jointly developed by multiple laboratories.

Among them, the bionic fish gills project is the cornerstone of the big project of the blue ocean, without which many sub-projects of the blue ocean project cannot be started.

When Midoqi heard Zhou Yu's intention, his expression immediately relaxed.

He took Zhou Yu into the laboratory and introduced: "Mr. Zhou, bionic fish gills are just one of the many projects in our bionic laboratory, its structure is not complicated at all, and it is the first project to be completed."

Zhou Yu walked into the laboratory, and he saw the finished product of the bionic fish gills.

There are two types of bionic fish gills, one is like an oxygen tube, which has two small tubes placed in the nose, and the end of the tube is a leaf-like substance.

The other model is a transparent semi-circular helmet with a beautiful cut-out pattern.

Midoch gave Zhou Yu a brief introduction to the bionic fish gills.

"We've developed a material that can separate oxygen from water, but it's not very efficient at all.

To satisfy one's breathing, the surface area of the material needs to be the size of a football field.

This simply cannot be put into normal use, and this rate of separation of oxygen is already the limit of the material in a short period of time.

We had to find a way to enhance the effect of this material.

Looking at the gills of fish, the efficiency of the gill cells in separating oxygen is not as good as that of our materials.

The gills are very delicate, and they help functional cells quickly separate oxygen from the water.

We used a quantum computer to repeatedly simulate the structure of the gills of fish to find out how it generated this special structure.

In the end, based on the original material, a bionic fish gilll product was manufactured.

It allows you to breathe freely in the water and swim in the water like a fish. ”

"How come you have two products, is it for different underwater environments? Can the two products really cope with the complex underwater environment? Zhou Yu pointed to the two products in front of him and asked.

Midoch first picked up two catheters, the bionic gills, and shoved the two protruding catheters directly into his nostrils, which pressed the product into his nose.

The foliage structure in front of it is attached to the cheeks on either side of the nose, and the catheter is tightly stuck on the bridge of the nose.

"This is a product for shallower water applications, where the dissolved oxygen in the water is higher and the water pressure is lower, and it does not affect the gills of this external bionic fish.

For every 10 meters of water, the pressure experienced by the object increases by one atmosphere.

Our human body is relatively comfortable and the depth of diving without tools is generally about 10 meters.

Spontaneous breathing is easier in this state, but once the water depth exceeds 10 meters, it becomes difficult to breathe.

This bionic fish gills, which are only placed in the nostrils, are prone to accidents when it is difficult to breathe on their own.

The pressure of the water also puts some pressure on the gill of the bionic fish, causing it to come out of the nostrils.

Taken together, these bionic gills can only be used in shallow water. ”

Zhou Yu nodded and asked again: "Why do you stuff the gills of this bionic fish in your nose instead of in your mouth?"

Midoch said the reason for their choice: "Mr. Zhou, this is a choice made carefully after a variety of situations.

There are two main effects, one is that humans are more accustomed to breathing through the nose, and only breathe through the mouth when it is difficult to breathe through the nose, and we follow our own habits.

The second is that they are novice users or in emergency situations, they cannot control their mouth or nose breathing, and often breathe with their mouth and nose.

The gills of the bionic fish are placed in the nose, and when the mouth and nose are breathed at the same time, the water enters the mouth, and the person can drink a small amount of water into the stomach by drinking water.

The body's response also reminds the user to breathe through the nose.

If the gills of a bionic fish are placed in the mouth and breathing through the mouth and nose at the same time, the water will choke on the lungs through the nose.

As long as a small amount of water is choked into the lungs, people will cough violently and cause serious discomfort, which is very easy to cause drowning accidents. ”

After explaining their reasons for their choice, Midoch placed the gills of the second bionic fish on his head.

"This kind of bionic gills belong to the real bionic gills, and the hollow pattern on its transparent helmet is set according to the structure of the gills.

This material does not allow water to pass through, but it can absorb oxygen from the water.

It works with a wetsuit, allowing divers to work in the water for long periods of time without the need for oxygen cylinders.

In water where dissolved oxygen is insufficient, it can seize the oxygen atoms in the water molecules to synthesize oxygen as long as it supplies power to the gills of the bionic fish.

In the lower part of the helmet, we have installed a carbon dioxide gas emission channel, even if you wear a bionic fish gill helmet in the water for a long time, you will not suffocate due to too much carbon dioxide. ”

Zhou Yu gave a thumbs up and exclaimed: "Your bionic gill development is very good, the shallow water version of the bionic gills is mainly used for entertainment, and the deep-water version of the bionic gills can prepare us for the future development of the ocean."

After encouraging the scientific researchers of the bionic laboratory, he left the bionic laboratory and walked towards the adjacent marine materials laboratory.

Bionic gills are a very promising product, and the deep-water version is mainly used to develop the ocean, where humans do not need external oxygen to supply oxygen and survive underwater for a long time, so as to complete the goal of marching into the ocean.

Humanity's knowledge of the ocean is not as deep as the understanding of the solar system, and there are too many secrets in the ocean waiting to be explored by the pioneers.

The shallow water version of the bionic fish gills is mainly sold to the market.

Every year, elementary and junior high school students drown due to playing in the water, and the water where the students drown is very shallow, but they die for various reasons.

Once the gills of bionic fish are on the market, these problems are no longer a problem.

The cost of bionic gills is very low, and Zhou Yu is ready to donate a batch of bionic gills to primary and secondary schools across the country.

Bionic fish gills are also a good tool for people to learn to swim, and some people have a natural fear of water, and can even drown in swimming pools.

As long as they wear bionic gills, they will definitely learn to swim.
