There is a slight difference between the hearts of men and women, but the difference is not too big and is acceptable. Pen, Fun, Pavilion www.biquge.info he didn't want to exchange Bai Zhi's life for Bai Shuo's life.

"Oh, that's it." She looked down in silent thought.

As soon as he saw Bai Zhi in this state, he didn't know what to say, the woman's cranky skills were too high, he was afraid that this girl would come up with some messy ideas for a while, so he hurriedly said: "You see, the artificial heart mainly includes blood pumps, valves, drives, monitoring, and energy systems, and I am going to use nickel-titanium zirconium alloy for this blood pump and valve, which is strong, lightweight, and has a smooth surface." Rejection is weak. It is the best choice for making artificial hearts. ”

In the earth usually artificial hearts, are used nitinol. Through several simulations, he found that this nickel-tin-tinol-zirconium alloy has better performance. Now some laboratories have begun to prepare this alloy.

The drive can be roughly divided into mechanical, electric, magnetic, pneumatic, and hydraulic. Five ways to do the same. All he had to do was to use Xiao Hei's simulation to create an electronic drive device that matched Bai Shuo's body. His choice is electric.

The terahertz wave technology used in the monitoring system has absolute advantages in monitoring the working status of the artificial heart, blood pump function, driving device and physiological parameters, which can better find and solve problems.

Why there are four hearts, mainly in energy, he made a distinction.

"The first heart, which is now a common in vitro battery, is now a common way to solve the energy problem of artificial heart, and its safety has been tested." He said and pointed to the first heart, which when enlarged, you can see a wire running from his chest down his body, with a square box at his waist.

Bai Zhi looked at the external battery and shook her head. In case something happens, the external battery is too prone to failure.

"The second heart, the built-in conventional lithium battery as an energy source, this energy technology is very mature, and there is no harm. The disadvantage is that it can only be used for two years, after which it has to be taken out, charged and put back. Of course, it can be made into an extracorporeal charging mode. It's just that there will also be a terminal head, which can be charged at regular intervals. It's just that every ten years you have to take it out and change it. He enlarged the second picture and displayed it on the second display, pointing to the USB port.

"You see, the multi-functional charging head I designed is the same as charging a mobile phone wherever I go. However, in this case, the heart will be about 900 grams, which will be very heavy. He explained the advantages and disadvantages of this heart.

Bai Zhi already had some excitement, but he still had two more to introduce, and asked, "What else?" You always keep the good stuff behind you. ”

"The further things go on, the more troublesome they become, and the cycle is a bit long. So I'll put it at the end. He said with a smile, zoomed in on the third image, and now said on a monitor: "Supercapacitor battery, once charged, does not need to be charged for life." It's just that this one is heavier than lithium batteries. It can be a big burden on a child's body. ”

He pointed to the place that was completely indistinguishable from the human heart and said, "You see, a supercapacitor battery is about the size of a canned beer." After all, it is a capacitive battery, and the energy density is a little lower. It's just that it has flywheel technology, which discharges while charging. ”

"And what about the fourth? What are you going to do with energy? Bai Zhi asked curiously, he said at the beginning that there were four, and the last one was a normal heart from the outside, if there was no introduction. She couldn't see what was motivating.

"The fourth name is nuclear-powered artificial heart, which has a practical example in the United States, but because there is no way to solve the waste problem, it still stays on paper, it can beat for 5,000 years, and the heart is still alive when people die." He explained.

"Won't there be too much harm?" Bai Zhi looked at the anatomical diagram carefully, and couldn't figure out how this thing could beat for five thousand years.

"No, I'll solve the radiation problem." He said confidently. The basic elements of this universe are unchanging, and there are many materials in the Galactic Federation, especially the prevalence of alloys. This kind of problem is the time for Xiao Hei to retrieve.

Bai Zhi asked stunnedly: "Will it bang and blow up, it's nuclear." ”

Explode? He thought about it carefully, the miniature nuclear battery, only as thick as a penny, so small, how could it explode? What kind of logic is this, is it that he doesn't understand enough? He nodded Bai Zhi's head and said, "You are still from 211!" It's a nuclear battery! It's not a nuclear reaction again! Explode! Blow up your head! It is through the decay of radioactive materials that charge particles are released, and a continuous current is obtained. The material I chose is plutonium-239, which decays to produce charged particles and a continuous current, understand? ”

"There are only two ways to kill people with this kind of battery, the first is leakage, plutonium is so poisonous that it basically poisons people in seconds. The second is radiation killing, but I'll do a good job of security, don't worry. ”

"Oh. I don't know, anything that is linked to nuclear is either an explosion, or a leak, or a radiation, or a dead person. ”

When Bai Zhi said this. He suddenly remembered a kind of website he had seen when he was a child. That site was a nightmare for him.

At that time, what was he like? 13 years ago, when he was just fifteen years old, when he went to the Internet café for the first time, he did his homework before going and wrote down the following matters in a small notebook: 1. Apply for an email. 2. Apply for a Penguin. 3. China's largest Yellow Pages website! And it was transcribed from a regular textbook!

When he opened the Yellow Pages website cautiously and solemnly, his heart was cold. This is the Yellow Pages!

Yellow! Page! Net! Stand! That's right, there are countless business names, countless phone numbers, countless corporate websites, and when he squatted in front of the computer to look at it, his jaw fell to the ground.

At that time, there was a yellow page next to the phone at home, and he didn't dare to turn it more than ten times. He just wanted to know why this thing existed! Say out loud: "I take off my pants, you show me?" ”

It was useless for him to wail, that thing was to record corporate information, not what he thought. Just like the current nuclear battery, anything that is hooked with nuclear is dangerous! Explode! Radiation! Death!

Where is this! This kind of thing is not so dangerous, the miniature nuclear battery of the United States uses super heavy hydrogen, and the plutonium he uses is only highly toxic, just seal it. Could anyone be pouring a big mouthful of super-heavy hydrogen? Or direct injection of plutonium? Is that something that takes a lot of brain pumping to do?

The high-speed electrons produced by decay have no ability to penetrate the human body, let alone the radiation-proof materials made by Zhao Heng himself, which are going for five thousand years.

"You're relieved, it's safe, it's not as dangerous as you think. I'll keep him safe, trust me! He said and hugged Bai Zhi in his arms.

Fortunately, when I did the super growth factor experiment, Angelica Angelica was not around, so if you see a rhesus monkey that has almost turned dry, you can't be scared? It was a scarier look than a terrifying look.

"I believe in you!" Bai Zhi raised her small fist and said. She didn't understand, so she just left it to him.
