PS. Present today's update, by the way, pull a vote for the "Biquge www.biquge.info" 515 Fan Festival, everyone has 8 votes, and the vote will also give the Biquge www.biquge.info coins, kneel and beg everyone to support and appreciate!

On the way back, Zhang Wenkai repeatedly urged Huo Yong to drive the car faster, because Zhang Wenkai was anxious to ask Xiao Na what the mystery of that iron meteorite was.

"Don't wait for the red light, just pass." Zhang Wenkai said with a wave of his hand.

Huo Yong was also unambiguous, fully showing what it means to listen to orders, running red lights all the way, and pressing the horn non-stop, just to achieve the speed that Zhang Wenkai is satisfied with.

The car was speeding on the street, Zhang Wenkai nodded with satisfaction, now everything is secondary, and returning to the company is the most important thing.

Soon arrived at the company, Huo Yong directly parked the car downstairs in Zhang Wenkai's private building.

Due to the fact that there are many secrets in the private building, the building is sealed all around and blocked tightly, so that it is absolutely impossible to see the situation inside from the outside.

Zhang Wenkai got out of the car, turned his head to Zhang Long and said, "Just send those literary toys to my office." After speaking, he went directly into the real yàn building.

As soon as I entered the building, I saw eleven machines standing in a neat row, shouting: "Master." ”

Of course, they don't have mouths, they make the sound of a horn through guò.

The eleven machine qì people were the first generation and the No. 1 and No. 2 machine qì people, and the later assembled machine qì people, Zhang Wenkai did not have any special names, so they were arranged in the back according to the number.

Looking at the ten cool-looking and very cold machines, Zhang Wenkai showed a smile, this will be his personal guard in the future, but he can't see the light.

"Number one to number ten, clean all the places." Zhang Wenkai commanded to the ten machines.

"Yes, master." The ten machines picked up the broom and began to clean it, Zhang Wenkai took the first generation upstairs together, and opened his mouth to ask while walking: "Xiao Na, what is the mystery of that meteorite?" ”

Cortana's projection was quickly revealed, and she said, "This meteorite contains a very rare metal, which is called Dimolten metal in the parent planet, and there is no such metal on Earth. ”

Di molten metal? Zhang Wenkai was stunned for a moment, and then asked, "What is the use of this metal?" ”

Since Cortana calls it a rare metal, it should be very rare.

"This metal is also very rare and precious on the home planet, and its properties are very similar to iron, and some people will confuse the two metals." Cortana explained.

Hearing this, Zhang Wenkai nodded, otherwise he would not have appeared in the iron meteorite.

"It is capable of accelerating the movement of electric current in a multi-frequency solenoid coil with an acceleration range of about a thousand times." Cortana continued.

Hasten? What is the use of the acceleration current? Zhang Wenkai still didn't understand.

Xiao Na naturally saw Zhang Wenkai's puzzled expression, and continued to explain to Zhang Wenkai: "With it, the volume of the multi-frequency electromagnetic coil can be reduced, and the function of the multi-frequency electromagnetic coil can also be strengthened. ”

Hearing this, no matter how stupid Zhang Wenkai is, he also understands the meaning, what does it mean if the multi-frequency electromagnetic coil the size of the manhole cover is reduced in size.

For a very simple example, if the size of the reduced coin can be installed in the mobile phone, in that case, the mobile phone does not need to be charged by itself, as long as there is a power conversion frequency transmitter terminal that has been emitting electromagnetism, it can be used all the time.

"How big can it get?" Zhang Wenkai asked the most critical question.

"It's about five centimeters in diameter." Cortana spoke straight to the answer.

Hearing the size of five centimeters in diameter, Zhang Wenkai was still a little disappointed, it was still not small enough!

"But the voltage it carries will be increased by a few cups and dozens of times." Cortana continued.

Hearing this, Zhang Wenkai swept away his disappointment, but was full of expectations.

What does it mean that the voltage is strengthened, it means that more powerful appliances can be driven.

On normal electric vehicles, the electric drive system used has a rated power, which also determines the power of the electric vehicle.

If you replace an electric vehicle with a more powerful electric drive system, the electric car can run faster and have more power, but it also consumes more electricity.

Normal electric vehicles set the power of the electric drive system according to the time of use and the amount of power storage.

If Zhang Wenkai can manufacture a multi-frequency electromagnetic coil with Di molten metal, it will break this rule, and electric vehicles can also have the same power as internal combustion engine vehicles, and they are permanent in terms of battery life, as long as there is an electric variable frequency transmission terminal that has been emitting electromagnetism.

There is a feeling of perpetual motion machine, and there is wood.

Zhang Wenkai suppressed the fanaticism in his heart, calmed down, and hasn't made it yet! There is no use in thinking too much.

"What do I need to do?" Zhang Wenkai asked calmly.

"Put it in strong acid, iron dissolves in strong acid, and what is precipitated is Di molten metal." Xiao Na described the preparation method for Zhang Wenkai in detail.

Now that he understood the real steps, Zhang Wenkai did not hesitate, and directly found two large bottles of strong acid and began to prepare.

Zhang Wenkai's real building is still very complete with equipment and materials like this commonly used real building, even if there is none, there must be one over there in the public real building.

Before preparation, you must take protective measures, which is a strong acid! If you don't pay attention, you will see Hades.

After being fully armed, Zhang Wenkai picked up one of the bottles of strong acid and unscrewed the cap.

I don't know if it's a hallucination, Zhang Wenkai faintly saw a puff of white smoke at the mouth of the bottle.

Carefully holding the bottle, pouring the strong acid into the glassware, and then using a large pair of tweezers, holding the iron meteorite, put it in.

It turned black and black visible to the naked eye, and Zhang Wenkai kept looking at this meteorite without leaving.

Soon the reaction stopped, because of the passivation.

This Zhang Wenkai was stunned, I wiped it, how did I forget about it, isn't Cortana teasing herself!

Xiao Na's image also appeared in time, and she said with a teary-eyed look: "People think you know!" "Cortana is talking about the fact that iron will dull when it encounters strong acid.

Zhang Wenkai covered his forehead and was speechless for a while.

"What now?" Zhang Wenkai asked Xiao Na, obviously Xiao Na deliberately teased herself.

"Ground into iron powder." Cortana's voice became stern this time.

Is it ground into iron powder? This is very troublesome, there is no such equipment in the real yàn room, but there is another way to make iron powder, and that is the crushing method.

It happened that there was such an instrument in the real yàn room, Zhang Wenkai took out the passivated meteorite from the strong acid, and went directly to the built-in workshop in the real yàn building to start processing iron powder.

After a piercing buzz, Zhang Wenkai turned back with a beaker, and inside the beaker was processed iron powder.

Greedy black code out of a chapter.,Make up for the one you owe yesterday.,Qilin eyesThank you for your attention.,Thank you.。

[It's about to be 515, I hope to continue to hit the 515 red envelope list, and the red envelope rain will be able to give back to readers and promotional works on May 15. A piece is also love, and it must be better! 】
