固体热胀机理的统计物理分析

The Statistical Physics Analysis of Solid Thermal Expansion

考虑原子振动的非简谐效应 ,从原子间相互作用势能入手 ,运用玻尔兹曼统计原理 ,推出了原子间距的变化与温度的关系式 ,并导出了固体的线胀系数 ,分析结果与实验是相符的。

The anharmonic effect of atomic vibration taken into account and from the potential energy which reacts each other among atoms Boltzmann statistical principle used the relation formula of temperature and the distance change between atoms and coefficient of linear expansion is derived.The analytical result and experiment are equal.
