摘要
首先导出聚集硬球分子模型状态方程,并应用该方程计算五种金属熔体饱和气的密度,取得满意的结果。还应用克拉贝龙方程,蒸汽压方程和状态方程计算了金属熔体的汽化潜热,所得结果与实验数据符合良好。
On the basis of the theory of molecular aggregation and the model for hard spherical molecule, the equation of state for molecular aggregation is derived by statistical thermodynamic method. Then, the densities of saturated vapor of 5 melting metallic substances are calculated by using the above equation of state, giving quite satisfactory results. In addition, the latent heats of vaporization of the same substances are also determined by using the Clapeyron equation and the above equation of state. The obtained results are in good agreement with the experimental data.
