论文摘要
提出了一种考虑到硬球模型框架中原子的远程潜力的方法。结果表明，热力学量可以表示为三个贡献的总和：理想气体的相互作用，硬球的相互作用和远距离电位。在密度的前几近近似值中，计算了病毒系数和由于电势平滑成分引起的热量的校正。注意以下事实：可以在自洽场模型的框架中描述由电势的远程部分确定的效果。
A method for taking into account the long-range potential of atoms in the framework of the hard-sphere model is proposed. It is shown that thermodynamic quantities can be represented as a sum of three contribution: that of an ideal gas, the interaction of hard sphere, and the long-range potential. In the leading approximation on density, the corrections to the virial coefficient and heat capacity due to the smooth component of the potential are calculated. Attention is drawn to the fact that the effects determined by the long-range part of of the potential can be described in the framework of the self-consistent field model.
