摘要： 本文简述了Eyring的有效结构理论及应用概况,并采用改进的参数求取方法,将此理论用于计算包括极性分子氢氰酸和吡啶在内的五种纯物质的液体热力学性质,结果与实验值符合良好.

Abstract: By modifying Eyring's significant structure theory, thermodynamic properties-molar volumes, entropies, molar heat capacities at constant pressure and constant volume——of liquid ethylene, ethane, hydrogen cyanide, carbon disulfide and pyridine are calculated. It is found that the results are in good agreement with experimental values.
