文摘Both the melting and evaporating efficiencies of the preparation process for ultrafine metallic particles by laser beam have been calculated using a physical model founded on an investigation of the energy interaction between a laser beam and the surfaces of Al,Cu and Mo samples.It shows that the above efficiencies of Al rank first,and those of Mo rank last.However those-of Al and Mo increase faster than those of Cu with increasing laser beam pulse intensity.
