The unscientific setting of the identification guide system is specifically manifested in the location, size and raw materials of the identification plate. Signs should be strictly in accordance with national standards and practices in terms of modeling design, setting and reasonable layout, with dark blue as the background color, attention to processing technology, and beautiful and conspicuous. At the setting level, according to everyone's habit formation and the basic principles of ergonomics, the aspect ratio, focal length, interval and text size of the sign are manipulated, in which the far focal length is 25 to 30 meters, the middle focal length is 4 to 5 meters, and the near focal length is 1 to 2 meters. The height-to-width ratio of the suspension is 2 to 2.5 meters. The size ratio of Chinese and English characters is 3:1; the font style is dominated by the standard Chinese bold type, and the interval set continuously is 50 meters.

The representative of a new generation of semiconductor materials-diamond, mainly for a new generation of electronic, microwave RF and optoelectronic applications. It has broad application prospects in the fields of new generation mobile communications, new energy grid connection, smart grid, high-speed rail transit, new energy vehicles, etc., and has gradually become a new strategic highland for the development of the global semiconductor industry.

What are the characteristics of sintered diamond and electroplated diamond?

Superabrasive grinding wheels made of diamond or cubic boron nitride (CBN) abrasive have been widely used in various aspects of grinding because of their excellent grinding performance. Diamond grinding wheel is a special tool for grinding hard alloy, glass, ceramics, gemstones and other high hard and brittle materials.

Hard diamond inlaid on a steel plate? All wrapped in a layer of nickel, this is electroplated diamond.

We all know that pencil lead is very soft and easy to be broken. There is such a substance that it is also made of carbon with pencil lead, but it is the hardest substance in the world. This is diamond. Because of the characteristics of hard and rare diamond, so since ancient times people will regard its precious stones, and after cutting polished diamond is called diamond, is one of the most precious stones in the world.

Photovoltaic industry diamond line special report: slice thin line promotion, tungsten wire diamond line penetration is expected to start.

The diamond wire is a linear super-hard material cutting tool, the structure includes the bus substrate, nickel coating, diamond powder particles, the main production process is: the method of electroplating on the steel wire substrate to deposit a layer of metal nickel, metal nickel layer wrapped with diamond particles, so that the diamond particles consolidated on the steel wire substrate. The demand for diamond wire downstream applications in the photovoltaic field accounts for more than 90%. Can be used for silicon rod truncation, silicon ingot square

Harvard scholars use high pressure to create the first metal hydrogen, peers have questioned: insufficient evidence

Many researchers are skeptical of papers that claim to compress hydrogen into a metallic state. Two physicists claim they turned hydrogen into metal by squeezing it with high pressure. For more than 80 years, physicists have been trying to achieve this feat.

Research Progress on Mechanical Properties of Diamond

Under pressure: Harvard researchers claim to have successfully squeezed hydrogen into a metallic state using diamond anvils, but the physics community is not convinced. The pictures in this article are all "Nature Nature Research" WeChat official account. Five experts told the "Nature" news team that they still don't believe this statement and still need more evidence to reach a conclusion. "I don't think this paper is convincing at all," said Paul Loubeyre, a physicist at the French Atomic Energy Commission.
