摘　　要：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 polarsubstance vapor and an intermolecular free volume model for liquid phase respectively, a newcubic reduced vinal EOS for gas phase ammonia and a new density equation for liquid phaseammonia have been proposed in this paper. Coupled with these eqilations, a new simpleVapor pressure of ammonia is also proposed. Results computed from these new proceduresagree well with experimental and literalured data.
