Abstract: The radial distribution functions and chemical potentials of supercritical NaCl-H ₂O system at 723.15K and 823.15K were studied by NVT ensemble MC molecular simulation.The chemical potentials were calculated by perturbation theory considering hard sphere, dispersion and dipole-dipole terms.The results show that the chemical potentials calculated from these two methods coincide with each other on the whole.

摘要： 用MC分子模拟方法研究了超临界NaCl-H₂ O体系的径向分布函数和化学势 ,并用考虑硬球、色散和偶极 -偶极作用项的微扰理论公式计算了相同体系的化学势 .结果表明两种方法计算的化学势基本相符
