Super hard network week news review (2.20~2.24)

I once asked a friend who is engaged in jewelry micro-business to marry her: "You have paid a lot of expensive jewelry, you must pay attention to your wedding ring. Would you like to buy a few carats of diamond ring?" She sincerely looked at it. I said, "I don't need a diamond ring, take a plastic ring, I will marry. Really love."
The relationship between marriage ceremony and jewellery is one thousand Hamlet in the eyes of a thousand people. Now diamonds have become a universally recognized indispensable marriage token, but if the diamonds in the market have natural and synthetic points, consumers will How to choose?
Synthetic diamond retailers are more willing to call synthetic diamonds “nurturing diamonds”. China's national standard: synthetic diamonds are the only name for gem-quality diamonds made by artificial methods, and ordinary consumers are still accustomed to using "true and false" to talk about jewelry, which may cause confusion for consumers.
In fact, both natural and synthetic diamonds are carbon elements with the same structure and properties. The fundamental difference between the two is that they grow in the deep part of the earth, and one is born in the laboratory by human hands.
Why re-interpret the facts we already know? Because if the accurate concept can be clearly understood from beginning to end, then it is not difficult for us to launch a series of rational thinking and actions.

5. Analysis of China's machine tool market and industry operation in 2016 ( read the original )
2016 is the first year of entering the "Thirteenth Five-Year Plan". In order to adapt to the "new normal" of China's economy and cope with the problems and difficulties in economic development, the Chinese government adopts the development idea of ​​supply-side structural reform as the main line, and At present, China's economic characteristics and actualities, put forward the "three to one, one reduction and one supplement" supply-side structural reform key tasks. In the coming period, "reform is the main line, stability is the bottom line" or it will become the main theme of China's economic operation. In 2016, under the combined effect of China's stable economic growth policy, especially the sound monetary policy and proactive fiscal policy, the operations in the real estate, automobile, service industry and new technology-based industries have experienced explosive growth, driving economic operations. Gradually stabilized. Affected by this, China's machine tool market and industry also showed a steady decline for the first time in six years (since 2011). In the following, according to the information and data of the national statistical bureau, customs and association industry statistics key contact network, comprehensive analysis of the current operating state and trend of China's machine tool market and industry.

6. Using diamond reinforcing materials to improve the fracture toughness of silicon carbide ceramics ( read the original )
As a hard high-strength material, silicon carbide is widely used in engineering equipment such as abrasives, rotary tables, bearings and high-temperature coatings. Poor fracture toughness caused by brittle traits is a technical constraint of silicon carbide. In recent years, researchers have developed and prepared nano-diamond (ND) particle-reinforced silicon carbide materials, which not only improve the fracture toughness but also the strength of the material itself. In this paper, molecular dynamics simulation was used to study the reinforcing effect of nano-diamonds and nano-silica particles in novel silicon carbide 131 materials. Two types of nanoparticles were selected for the experiment: (a) clustered particles in front of the crack tip; (b) uniformly distributed particles. The fracture toughness of Model I and Model II was measured. Experimental observations show that the addition of nano-diamonds in silicon carbide can improve the fracture toughness of model II by 100% and improve the fracture toughness of model I by 25%.

7, the elderly coronary artery severe calcification diamond spin through the vascular barrier ( read the original )
Director Sun Zhonghua explained that severe coronary calcification is a layer of hard material on the wall of the arterial wall, which is equivalent to heavy barriers. Ordinary interventional surgery can not expand the blood vessels. Only the rotating head with high speed is used to cut the plaque and open the barrier. In order to ensure the smooth follow-up. Rotary grinding is an olive-shaped rotary grinding head with diamond particles. According to the theory of "differential cutting", the calcified or fibrotic arteriosclerotic plaque is selectively removed, and the elastic vascular tissue is rotated at a high speed. When the head passes, it will automatically bounce off, that is, the atherectomy head does not cut the elastic tissue and the normal coronary artery, and will not damage the normal blood vessels. After atherectomy, the plaque will be polished to a smaller size than the red blood cells. The debris is swept away by the bloodstream to the distal end of the blood vessel and is engulfed and metabolized by human macrophages. Coronary atherectomy is an important method for the treatment of severe calcification of coronary arteries. Proper use can effectively ablate coronary calcification and create good surgical conditions for the final placement of coronary stents.

8. Two national standards drafted by Zhongnan Diamond Company were wholesaled ( read the original )
