Chapter 109： Year ceremony (below)

The development of explosives has gone through four stages. At present, the internationally accepted saying is based on the speed of the detonation wave when explosives are exploded, and the explosives are divided into four generations.

The first generation of explosives was "nitroglycerin" discovered by Nobel. The second generation of explosives is a trinitrotoluene that played a significant role in World War II. The codename is a strong explosive that is synthesized by artificial organic synthesis. It has a strong explosive capacity and is stable in nature. It can be used for intensive fire shooting of organs and artillery, making war cruel. Greatly improved, still used a lot.

The third generation of explosives, Black Sokin, was produced after World War II. Its detonation speed reached m/s, which was used to suppress the scale of multi-barrel rocket heavy artillery. It can greatly increase the power and range of weapons; secondly, the detonation speed reached 9000. The meter/second Oktokin has a slightly higher impact sensitivity than tnt, is easy to detonate, has good stability and high comprehensive performance. In the Gulf War, it is used for non-contact asymmetric warfare of long-range rocket missiles. "

The cl-20" explosive is the non-nuclear single explosive that is currently known to be the most energy-efficient and powerful.

This new type of explosive has a detonation speed of up to 9,500 m/s. It is known as the "fourth generation of explosives" and is also known as "breakthrough energetic materials." It is an epoch-making new high-explosive military explosive that is in the world. The explosives industry is well known.

The energy of cl-20 is 1.8 times tnt equivalent. The most straightforward understanding is that the explosion energy of a kilogram of cl-20 is equivalent to the power of a 1.8 kilogram tnt explosion. (

The above is the data excerpt)

In this high-energy explosive, it 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 the engineering production was completed in China, and the 2015 National Defense Science and Technology Progress Award was won. "

Just kidding, joking, don't make fun of this kind of thing! "Zhao Xiangbei almost came out with cold sweat. Fortunately, it is just a name. It is not a military secret, otherwise it will be troublesome."

Cut, it is not the most powerful! Guo Tailai muttered in a low voice, no longer talking about this question.

After chatting a few words, Guo Tailai specially asked the situation of the teacher and sister. After she knew that everything was fine, she would not stay longer and leave. Of course, before leaving, I also specifically asked Zhao Dong what I liked most. Although a pair of combat boots have been prepared, for the glamorous Ding, this can only be an auxiliary mind, or it is better to pick her favorite.

"Hey, fuck!" Zhao Xiangbei indulged, and finally said: "In fact, she still likes some beautiful jewelry. I have never sent her in these years, hehe!"

"Received!" Guo Tai came to understand the second, patted his chest and said: "I promise to make Ding Aunt happy!"

"Roll!" Zhao Xiangbei always felt that something was wrong, but for a moment did not ponder over the taste, see Guo Tailai sitting in front of him, intending to send jewelry to his wife, but only give him a pair of shoes, could not help but irritated: "Don't be me In front of the eye!"

Guo Tailai immediately obediently rolled away and quickly disappeared. "

Sister Wu, do you sell jewelry that doesn't sell thousands of gold in your store? "Leaving Zhao Xiangbei, Guo Tailai called Wu Shanshan. Wu Sister is the general manager of Beijing Fuling Jinxing. Should she always have gold to sell?"

It’s definitely not appropriate to give the mother a mother a diamond, or use the gold of the pen, everyone likes it. In addition, Guo Tailai decided to buy a few suitable ones for his mother, can not be thicker than this!

Wu Shanshan certainly has no problem here. He directly invites Guo Tai to come to her store to see it. As long as Guo Tai comes to see it, he will only accept the gold price and will not charge the processing fee. Guo

Tailai drove directly to the address that Sister Wu said. Fortunately, without traffic jams, it took only half an hour to get to Scitech. Sette has the counters of Fuling Jinxing, which looks very tall. When Guo Tailai passed, Wu Sister was waiting there and accompanied him. listen

Guo Tailai is planning to give her mother, Wu Dajie's enthusiastic recommendation bracelet. Basically, the gold bracelet can be said to be a killing weapon for women of all ages. As long as it is delivered, no one will dislike it. only

Yes, after a lap, Guo Tailai discovered that he did not even look at any one. It’s not that the style is too old, it’s like a long, and there’s no one that can let Guo Tai see it. gold

Not only do gold jewelry, but also some jewel jewelry, but Guo Tailai also did not see the eye, just shaking his head.

"Little brother, what do you want in the end?" Wu Shanshan is not annoyed, Guo Tailai, such a master craftsman, certainly has a high vision, so she fully understands. "

I want that kind of..." Guo Tailai reached out and gestured: "Exquisite, exquisite workmanship, an eye-catching jewelry." It is best to be the one that is unique, or to take a step back, how can it be the best of the limited edition, is there any? ”

"There is nothing unique, but you have to be the best, then it is difficult." Wu Shanshan smiled bitterly: "Master hand-made works, can not do a few pieces a year, you come unfortunately, the last batch has just been picked up If you have been waiting for a few months, can I order two for you?"

"I intend to be a gift for the Spring Festival." Guo Tailai also smiled bitterly. If he waited for a few months, the time would definitely be too late.

“Would you like me to recommend you to visit other stores?” Wu Shanshan did not feel annoyed because Guo Tailai did not choose something. Instead, she enthusiastically suggested: “The capital is so big, there is always something you like.”

Forget it, I will come by myself! Guo Tailai pondered for a while and thought about some things he saw in the future dreams. He finally made up his mind: "Big sister, are you selling thousands of gold here?" I buy a batch and go back and do it myself! ""

do it yourself? "Wu Shanshan stunned, and immediately thought of the kind of tactics that Guo Tailai used to repair and maintain the watch. Suddenly, Wu Shanshan had some expectations that Guo Tailai would make it by hand."

Little brother, this way, the material I am out, you out of the manual, the finished product you made to leave a big sister, how? "Wu Shanshan is also a very savvy businessman, and immediately decided to make a decision."

"Don't!" Guo Tailai hurriedly stopped, and he had to send one to Ding. How can it be so cheap? However, Wu Shanshan is also a triumphant boxing, Guo Tailai instantly came up with a thoughtful plan: "In this way, the material I bought at the price, made something, put a piece of your sale here, see the effect and say."

It was also safe, and Wu Shanshan did not think about it, and immediately agreed. I have no loss for myself, and I can see Guo Tailai’s craftsmanship again.

At the same time that Guo Tailai and Wu Shanshan reached an agreement, Zhao Xiangbei finally figured out what was wrong. Guo Tailai, this little bastard, looks like he still muttered when he talks back. What is not clearly heard, but there must be problems.

Do not joke with cl-20, Guo Tailai seems to be dissatisfied? What is the most powerful high-energy explosive known, why is Guo Tailai not convinced? Does he still know more? miss you

Here, Zhao Xiangbei slammed his thighs, yes, it must be.
