There is only one reason for shrinkage cavity and porosity of die castings, which is the inevitable phase transformation shrinkage when the liquid phase changes to the solid phase after the metal melt is filled. Because the solidification characteristic of die castings is cooling from outside to inside, when the casting wall thickness is large, the problem of hole shrinkage and looseness will inev···
Accelerator is a device that accelerates particles to obtain high energy. In the accelerator, electrons, protons, deuterium, a particles and other heavy ions of various energies can be generated. The interaction between these particles and matter can also produce various charged and uncharged secondary particles, such as 7 particles, neutrons, various mesons, hyperons, antiparticles, etc. The part···

X-ray machines can be divided into medical x-ray machines and industrial x-ray machines according to different application fields. Medical x-ray machines are mainly used in hospitals. Industrial x-ray is x-ray flaw detector, which is widely used in aerospace, military, automotive parts, electronic parts, pressure vessels, pipelines and other industries.Portable industrial X-ray machines can be div···
