几种固体模型下的固气相变蒸发热的计算

Compution of the Vapor Heat on the Enistiein and Debye Solid

用固体的Einstein模型与Debye模型分别导出相应模型的固气相变的蒸发热和蒸发压公式,并对其做了数值计算。结果表明,蒸发热与温度之间近似呈线性关系,这与工程上经验近似是一致的。

The formulas of vapor heat and of vapor pressure is derived and computed by the Enistein and Debye solid model.Result in the quantity of vapor heat changes linearly with temperature.The result is consistent with the assumption in engineering.
