| 摘 要： | 本文统一地从点阵动力学关于晶体振动频谱的普遍关系出发,导出了三种不同固体的特征振动频率表达式,并由此重新导出了rS、rD-M和rf,说明rS,rD-M和rf从属于不同的固体模型。然后导出了固体的特征频率及Grüneisen系数的普遍表达式。

| Abstract: | Starting from the general expresson of frequency given by the dynamical theory of crystal lattices, we have derived three different expressions of the characteristic frequency for three kinds of solids, and re-obtained rS,rD-M and rf. We pointed out that rS,rD-M and rf. belong to three different models of solids. Finally, the general expressions of the characteristic frequency ω and Grüneisen coefficient γ for solids were found. |
