摘要: 采用重整化理论对材料在冲击熔化去的强度进行了分析，分析结果表明在冲击熔化区内，材料的强度在熔化质量分数达到0.300 798时开始减小，与材料中纵波声速向体波声速的转变点相对应。

Abstract: The material strength in shock-induced melting region was analyzed with renormalization group theory, it indicates that the material strength begin to decrease as soon as the melting mass fraction reach 0.300 798, corresponding to the point at which the longitudinal sound velocity initially turn to bulk sound velocity.
