The gymnast puts some "magnesium powder" on his hands before putting on the horizontal bar: The scientific name is "magnesium carbonate", which is commonly referred to as "magnesium powder" is the wrong scientific name. Magnesium carbonate is very light in weight and has a strong hygroscopic effect. When athletes are playing, the palms of the palms often sweat, which is very unfavorable for gymnasts and weightlifters. Because the slippery palm will reduce the friction, so that the athlete can not hold the device, not only affects the quality of the action, but also causes the athlete to fall from the device, causing mistakes and even injuries. Magnesium carbonate absorbs palm sweat and increases the friction between the palm and the instrument. In this way, the athlete can grip the device, which is conducive to improving the quality of the action. Because magnesium powder emits intense light when burned, early camera flashes used light from burning magnesium powder. The early flash was also turned into a spotlight (this name is still visible in some places to date), and the disadvantage of ordinary spotlights is that they can only be used once. It has now been replaced by an electronic flash. Currently, electronic flashlights are used on optical cameras and digital cameras. Diffused Silicon Pressure Sensor The diffusion silicon Pressure Sensor adopts the diffusion silicon piezoresistive pressure sensor with stainless steel isolation film as the signal measuring element, the signal processing circuit is located in the stainless steel housing, the sensor signal is converted into standard 4-20mA current or RS485 signal output through the professional signal conditioning circuit. Widely used in petroleum, chemical, metallurgy, electric power and other industrial process on-site measurement and control.
