| 摘 要： | 利用工质的音速与第二维里系数的关系,推导出第二音速维里系数与分子间势能函数的关系式,提出了一种新的拟合分子间势能模型参数方法.并利用此方法,拟合得到了一些简单流体和制冷剂的的方阱、LJ(6,12)及Kihara等势能模型的参数.与传统方法相比,该法拟合势能参数具有更高的精度.

| Abstract: | In order to determine the intermolecular potential (including square well, Lennard Jones, Kihara, Stockmayer and etc.) parameters, a new method was developed with the relationships of the second virial coefficient, the second acoustical virial coefficient and the intermolecular potential function. With the new method, the intermolecular potential (SW, LJ, Kihara) parameters of simple fluids and refrigerants were determined. Compared with the typical method, the new method has more accuracy and dependability. |
