The installation of the explosion-proof pipe heater can directly heat the material to be heated, and can perform repeated heating at high temperatures to save energy. There are data investigations showing that ex.......
Valve manufacturing process characteristics
Lead: The first few valve parts, simple structure, accuracy in general, are simple parts in the machinery industry, but the valve core sealing parts are particularly demanding. Valve manufacturing process is complex, technical difficulty .......
Users choose the pump, it is best to the agricultural machinery department approved point of sale, we must recognize that the manufacturer. It is recommended to give priority to the purchase of water-filled submersible pump, and see the grades and product quality certification. Do not buy .......
This is a schematic of a photon gun. Quantum dots (yellow symbols) each emit one photon (red wave packet). The quantum dot is embedded in a photonic crystal structure that is obtained by etching holes (black circles in the figure) in the semiconductor material. B.......
The holographic atomic memory invented and manufactured by physicists at the Department of Physics in Warsaw University is the first device that can generate single photons on-demand with tens or more per group. This device, which has been successfully proven, overcomes one of th.......
