本文根据新导得的当量分子作用势函数和分子自由体积理论，建立一组形式简便、精度高的氨工质新三次维里状态方程、蒸气压方程及其液相密度方程，具有显著的工程应用价值。
By using an equivalent intermolecular potential function,L-J(6-12),for polar substance vapor and an intermolecular free volume model for liquid phase respectively,a new cubic reduced virial EOS for gas phase ammonea and a new density equation for liquid phase ammonia have been proposed in this paper.Coupled with these equations,a new simple vapor pressure of ammonia is also proposed.Results computed from these new procedures agree well with experimental and literalured data.
