Piaotian literature crystal is a large colorless transparent large quartz crystalline mineral .. Its main chemical ingredients are silicon dioxide. Its color is mainly colorless, purple, yellow, green and smoke, etc., and has glass luster, transparent, transparent, transparent
To semi -transparent.
Crystal and ordinary sand are a substance of "the same mother's fetal".
When the silicon dioxide crystals are perfect; the agate is agate after the dehydration of the silicide gum; the silicon dioxide has a water -containing colloid to become a protein stones; when the silicon dioxide grain is less than a few micron, it forms a chalcedony, vermiculite, secondary life, and the second birth.
Quartz rock.
Pure colorless transparent crystals are quartz variants.
The important production of amethyst state, the state, the state, the Ural Mountains in Brazil, Uruguay, Russia, India, Madagascar, Nepal, the United States and Mexico, these countries have also produced colorless and transparent crystals.
Shanxi, Shandong, Xinjiang, Inner Mongolia, Guangdong and other provinces have purple crystal outputs, and more provinces produced in colorless crystals, but the most famous of which are the following two: Yangjiaoling in Hainan Province and Donghai, Jiangsu Province
county.
Crystal is physically chemically stable. Its piezoelectricity and elastic properties make them mechanically vibrate on electrical, with high Q value, low dynamic rate, high acuity, high stability and other excellent rate characteristics.
Then, then
Therefore, all the shocks that require highly precise and stable frequencies, the filter must use crystal to make the oscillating material. Its use is synthesized, counting, navigation, guidance, fax, computer, communication, timing, etc.
See the importance.
Experts and scholars have been studying in the crystal for many years. The crystal has been determined to have five major functions: focusing refraction, storage information, transmitting messages, energy conversion, energy expansion.
In the information obtained by Zheng Xiao, the Yanhuang Legion once had a study that specifically for the application of crystal function in military.
If this crystal wall is really a natural crystal, then it is really rare. It is more appropriate to use research.
However, Zheng Xiao, the first problem that they are going to solve now, such as the turbulent water flow, otherwise, I am afraid that nothing can be done.
After retreating three or four meters, the water surface finally stopped rising, and people felt relieved.
Zheng Xiao looked at the surface not far away, and then said back, "It is not a way to wait like this. You must prove the specific situation of the underground river opposite."
In this Guan Dongshan, the underground river is not one, and sometimes there are hundreds of underground rivers under the same mountain range. They connect each other and staggered, forming a spider web -like network. When people enter, people can easily lose their directions.
Coupled with the most in the underground river is the dark fluid vortex. I do n’t know where to pass. It is very dangerous. I lost it without paying attention to my life.
It is not yet determined that this underground river is the underground river where the underground cave they are looking for. It must be determined.
The two special combat players changed into the diving clothes, then jumped into the water, then dived in the underground river, tied a rope between their waists, and once they encountered something, they could drag the two people back.
The two got out of the water and soon disappeared. Except for the wavelets brought by the waves on the water, nothing could be seen.
The four special combat players each grabbed a rope, concentrated on watching the water surface, and prepared to pull the rope at any time.
Underwater, especially unfamiliar underwater, there are always various dangers. Some people do it and are naturally generated. Once people encounter, they are dangerous.
The time passed by every minute, there was still no movement in the water, and Zhuge Hong squatted beside him, with a small display in front of him. Inside, two special combat players used a micro -underwater camera to carry a micro -underwater camera.
The situation is not shot at all.
In the camera, the two were still moving forward. It seemed that they had swim from the crystal wall and came to the underground river.
The river of the underground river is very clear. Perhaps because there are mountain spring water everywhere, there are many scum. The two special combat players are in the water, and the surrounding environment can be seen clearly.
Around their bodies, water flows everywhere. This underground river seems to be wide. The camera does not see the bank of the river at all. It can only be a large area of water.
In the underground Hanoi, there are not many scattered stones, but they are covered with tapped stones, which allows the two special combat players to act carefully.
In this way, the two continued to move forward and walked along the underground river.
At this time, everyone surrounded the display and stared at the picture inside,
The underwater world is particularly complicated, so when the two people walk, they are very careful when they walk, and they are afraid that they will violate any dangerous places, so the speed is very slow.
In this way, in the camera, the two were finally close to the source of the underground river, a spring eye with a sprout.
The diameter of this spring eyes is about twenty centimeters, and spring water is erupted from outside. The flow is not small. Most of the water flow in the underground river is the spring water of this spring eye.
Two people reached out and grabbed the shore, then turned over, and unravel the diving equipment of the whole body.
Zheng Xiao didn't want to let them go, but the data of the underground river always needed people to get it. The two special combat players worked hard and proved things in the depths together.
The camera was on the shore as the two people's bodies, and then moved forward, and continued to project the situation above the water surface. Everyone seemed to be in the state of immersive.
"Captain, this is the source." Two special combat players stopped, and a stone mortar at his fingers said, "Most of the water flow in the underground river is provided here."
Zheng Xiao nodded and asked, "Is there at the end of the underground river?"
"No, the captain, Quan's eyes are just the beginning of the stone cave, and there seems to be a far away from the back." After careful observation for a long time, after confirmation, the two answered Zheng Xiao's question.
After listening to the narrative of the two people, Zheng Xiao was happy in his heart. He felt that the cave was likely to be the underground cave that was looking for, because the two were really coincidental.
Zheng Xiao thought about it. In order to determine that this is the underground cave, he ordered the two special combat players to push the camera forward to detect how long the cave is.
The camera was moved to the depths of the cave.
Although I didn't see anything later, Zheng Xiao was initially determined that this was the underground cave they were looking for.
