Trillions of market capitalization is not a dream

"Trillow City is not a dream novel ()" to find the latest chapter!

Looking at Zhao Manfu, Zhou Wencheng looked at the beauty of CCB Xiao Wang to re-packaged the gold bars.

This is not God, what is it, since I gave me an opportunity to God, it is natural to catch it.

Zhou Wencheng comforted Zhao Manfu: "Zhao always, don't be angry. I think this packaging is naive. At that time, I didn't find this time when the bank staff was packaged.

This matter is for us, the packaging is a little thing. If the gold bars are really there is no problem.

Or is the true and false of gold bars.

Zhao, you open it directly. "

Zhao Manfu listened to Zhou Wencheng, opened the gold bars, and took the gold bob and checked it.

Finally, I put down the gold bars: "I don't know what method to check the true and false of the gold bars.

Buffet on TV, you are too big, you can't bite. "

Zhou Wencheng smiled: "Forget it, I still ask the professionals."

After that, I took out my mobile phone. I found the phone number of the first branch of Nanshan City, the first branch of Nanshan City, and then said: "I am Zhou Wencheng, just buy the gold bars."

Surprised voice came: "Hello, Mr. Zhou, is you checking the gold bars so soon?"

Zhou Wencheng laughed: "No.

Because this gold bar is very important to us, it is absolutely can't be fake, we want to verify, but do not understand the method of verification. "

After that, Zhou Wen became hands-free, put it in a few tables with Zhao Manfu, so that both people can hear the communication content of the phone.

"So, I guess you call me, I want a person who sells gold bars to you, how do you verify the true and false gold bars, right?"

"Yes, this is what I think."

"Then, you can believe that my statement, will not think I am doing a lot of gold bars?"

"I believe that you will not lie to me.

"Well, you will follow this brain."

"I will barely explain it."

"You have seen the costume TV series, is there any gold?"

"Yes."

"Then you now take it out, how?"

"Really bite?"

"Of course, this is the simplest identification method, do you understand?"

"Don't understand, I still bite it."

"Some brick houses say that real gold will leave a touch of dental printing after biting, because the purity is a bit soft, unprinted, and can't bite to teeth."

"I am a little dental printed, it seems to be true gold."

"Don't worry, experts have not said yet."

"Then you will say."

"Experts say that the Moh's hardness of human teeth is 6, and the relative Moques hardness of gold and silver is 2.53, pure copper is 3, iron is 4.

Therefore, gold, silver, copper, iron, iron material is not high, bite with teeth, bite, as long as the strength can leave a conspicuous teeth printer.

In summary, the true and false of the human teeth are distinguished from the human teeth. "

"Ah, this way, no, this block of gold has already bitten, I want to return."

"You bite yourself, let me have anything."

There are other different methods, should you continue to hear? "

"Why don't you listen?"

"Is there a magnet in your hand?"

"Now no, if you need, wait for it to find a piece."

"The magnet is sucks sucks to test the true and false of gold.

If the golden product contains other metal impurities, it is sucking with the ironing stone. If you can succeed, it means that the gold has more impurities, which is the golden gold.

This sentence is true.

However, scientific knowledge tells us that there is only three metal, cobalt and nickel, which can be sucked by the magnet.

Therefore, if the gold fake is not added to three metals, cobalt and nickel, the magnet method cannot be detected. "

"Well, this can be understood.

Waiting for a magnet to suck it, if you succeed, you must find you return. "

"Line, if you succeed, then return. But there is no toothprint can't refund, you have to restore the original."

"Is there any other identification method?"

"Yes. General testing can be used to use density algorithms to exclude partial blended gold.

Gold density is 19.26 grams of centimeters to 19.37 grams of centimeters.

It can be used to select a high precision cup, and put the quantified water such as 200 ml.

Put the gold bars into the water, it is necessary to pay attention to the gold bars to be overwhelmed.

The volume of the new water is measured, for example, 350 ml of -200 ml = 150 ml.

This 150 ml is the volume of the gold bars.

The quality and volume of the gold bars are known, and naturally, the density of the gold bars can be smoothly calculated.

If the density of this calculated gold bars are within the range of standard values, then the gold bars have a high possible possibility, otherwise it may be blended.

It should be noted that this method can eliminate most of the blend gold.

However, if the pseudo gold is strict, the scientific ratio adds other suitable metals.

We can't identify.

For example, the counterfeiter is incorporated into ruthenium, tungsten these two metals, and their specific gravity is similar to gold, and only the method of detecting only the density is not identified. "

"Well, I know, this is a density method, is there another simple point of identification?"

"It is simple.

Physical bending can also be used.

This method is suitable for gold bars of the sheet process. Before purchasing, you can bend the gold bars themselves.

If the gold strip is very high, if the gold bars, the gold bars can be curved.

If the purity of the gold bars is low, the color is poor, then the difficulty of curvature will be relatively high, and the ordinary person is handless, it is difficult to let the gold bars bend. "

"It is not suitable for this kind of way to use this kind of way."

"Do you have a bow, can you be bent?"

"I really can. I am curious, will the gold bars will be broken?"

"Don't worry, don't worry, how much is a little gold, and the ductility after composite is also better, and I haven't heard which person who is free of hand."

"This method knows, please tell the next method."

"The next method, it is estimated that you like it."

"Oh, listen to it."

"This method is: firefighting method.

Melting the gold bars with a high temperature flame, and other impurities will naturally separate from the gold bars.

This method can accurately detect whether the gold bars are incorporated.

But it also completely destroyed the process of the gold bars themselves.

This method is to see if you apply it. "

"It's too unable to apply, burning broken, it turns into gold, how difficult it is."

"It's really a bit hard, I said that I have been so long, wait for me to drink the water, and then say it."

Zhou Wencheng quickly slammed the microphone of the phone: "Zhao always, the true and false identification is too difficult, will we continue to consult?"
