Chapter 218 Annual Ceremony (Part 2)

The development of explosives has gone through 4 stages. The current internationally accepted saying is to divide explosives into four generations based on the propagation speed of the detonation wave when the explosive explodes.

The first generation of explosives was "nitroglycerin" discovered by Nobel. The second-generation explosive is trinitrotoluene (code-named TNT), which played a great role in World War II. TNT is a highly explosive artificially synthesized organically. It has strong enough explosive power and stable properties. It can be used for intensive fire shooting of machine guns, which greatly improves the brutality of war. It is still widely used until now.

The third-generation explosive RDX was produced after World War II. Its detonation speed reaches 8500~8600 m/s. It is used for the large-scale suppression and strike of multiple rocket heavy artillery, which can greatly improve the power and range of weapons; followed by detonation Oktokin, which has a speed of 9000 m/s, has a slightly higher impact sensitivity than TNT, is easy to detonate, has better stability, and has high comprehensive performance. In the Gulf War, it was used for non-contact asymmetric operations of long-range rocket missiles.

"CL-20" explosive is the highest energy and most powerful non-nuclear elemental explosive known to be practically applied.

This new type of explosive has a detonation velocity as high as 9,500 m/s. It is called the "fourth-generation explosive" and is also known as "breakthrough energetic material". It is an epoch-making new high-explosive military explosive. Explosives is well-known.

The energy of CL-20 is 1.8 times the equivalent of TNT. The most straightforward understanding is that the explosion energy of one kilogram of CL-20 is equivalent to the power of an explosion of 1.8 kilograms of TNT.

(The above is an excerpt from the information)

At present, this high-energy explosive can only be produced in the laboratory, and has not yet formed the capacity for industrial production. In the dream of the future, it was not until 2015 that domestic engineering production was completed, and it won the 2015 National Defense Science and Technology Progress Special Award.

"From now on, just make fun of it. Don't make fun of this kind of thing!" Zhao Xiangbei almost broke out in a cold sweat. Fortunately, it was just a name, not a military secret, otherwise there would be trouble again.

"Cut, it's not the most powerful!" Guo Tailai muttered in a low voice, and stopped talking about this issue.

After chatting for a while, Guo Tailai asked the senior sister about the situation there, and after knowing that everything was fine with her, he didn't stay any longer, took his leave and left. Of course, before leaving, I also specifically asked Mr. Zhao what Mr. Ding likes the most. Although I have already prepared a pair of combat boots, for the glamorous Mr. Ding, this can only be an auxiliary idea, and it is best to choose what she likes.

"Damn Yanyan!" Zhao Xiangbei pondered for a while, and finally said: "Actually, she still likes some beautiful jewelry. I haven't given her any these years, alas!"

"Received!" Guo Tailai understood in seconds, patted his chest and said, "I promise to satisfy Aunt Ding!"

"Get out!" Zhao Xiangbei always felt that something was wrong, but he didn't think about the taste for a while. Seeing Guo Tailai sitting in front of him, he was going to give his wife jewelry, but he only gave him a pair of shoes, and couldn't help getting annoyed: "Don't be in my shoes." It's an eyesore!"

Guo Tailai immediately rolled away obediently and disappeared quickly.

"Sister Wu, do you sell pure gold jewelry in your store?" After leaving Zhao Xiangbei, Guo Tailai called Wu Shanshan. Sister Wu is the general manager of Fuling Gold Co., Ltd. in Beijing. There must be gold for sale there, right?

It's definitely inappropriate to give diamonds to the mother-in-law. It's better to use the gold that is your duty. Everyone likes it. In addition, Guo Tailai decided to buy a few suitable ones for his mother, so he can't favor one over another!

Of course, there is no problem with Wu Shanshan, and she directly invited Guo Tai to come to her shop to have a look. As long as Guo Tai came to see it, she was guaranteed to only charge the gold price and not charge processing fees.

Guo Tailai drove directly to the address that Sister Wu said. Fortunately, there was no traffic jam, and it only took more than half an hour to arrive at Dorset. There is a special counter of Fuling Gold Company in Dorset, which looks very tall. When Guo Tailai passed by, Sister Wu was waiting there and accompanied him all the way.

Hearing that Guo Tailai planned to give it to his mother, Sister Wu enthusiastically recommended the bracelet. Basically, gold bracelets can be said to be a killer weapon for women of all ages. As long as they are given as gifts, no one will dislike them.

However, after looking around, Guo Tailai found that he didn't like any of them. Either the style is too old, or the appearance is average, there is no such thing that Guo Tai can look in at a glance.

Jinxing not only makes gold jewelry, but also some gem jewelry, but Guo Tailai also didn't pay attention, just shook his head.

"Little brother, what exactly do you want?" Wu Shanshan was not annoyed, a master craftsman like Guo Tailai must have a high vision, so she completely understood.

"I want that kind..." Guo Tailai stretched out his hand and gestured: "Exquisite, exquisite workmanship, and eye-catching accessories. It's best to be unique, or take a step back, it must be a limited edition Superb, is there any?"

"There are unique ones, but if you want top-quality ones, that's difficult." Wu Shanshan smiled wryly: "Master's handicrafts can't be made a few pieces a year. It's unfortunate that you came here. The last batch has just been selected. , why don't you wait a few months, and I'll order two for you?"

"I plan to take it as a gift for the Spring Festival." Guo Tailai also smiled wryly. If he waited for a few months, it would definitely be too late.

"Why don't I recommend you to look at other stores?" Wu Shanshan was not annoyed because Guo Tailai didn't choose anything, but suggested enthusiastically: "The capital is so big, there is always something you like."

"Forget it, I'll do it myself!" Guo Tailai pondered for a while, thought about some things he saw in the future dream, and finally made up his mind: "Sister, do you sell thousands of pure gold here? I'll buy a batch and go back and make it myself!"

"Do it yourself?" Wu Shanshan was taken aback for a moment, and then thought of Guo Tailai's amazing technique when repairing and maintaining watches.

"Little brother, how about I supply the materials, you supply the handwork, and leave one of your finished products for the elder sister?" Wu Shanshan is also a very shrewd businessman, and she made a decisive decision immediately.

"Don't!" Guo Tailai hastily stopped him, he wanted to give Mr. Ding a piece, how could he take advantage of it? But Wu Shanshan was also kind, and Guo Tailai immediately came up with a thoughtful plan: "In this way, I will buy the materials according to the price, and put one of the things I made for sale with you, and see the effect."

This is safe, Wu Shanshan didn't think much about it, and immediately agreed. I have nothing to lose, and I can see Guo Tailai's craftsmanship again, killing two birds with one stone.

While Guo Tailai and Wu Shanshan reached an agreement, Zhao Xiangbei finally figured out what was wrong. Guo Tailai, the little bastard, seemed to mutter something when he talked back to him. I didn't hear what it was, but there must be something wrong.

You are not allowed to make jokes about CL-20, Guo Tailai seems to be still not convinced? Why is Guo Tailai not convinced by the most powerful high-energy explosive known? Does he know something more powerful?

Thinking of this, Zhao Xiangbei slapped his thigh suddenly, yes, it must be like this.
