摘　　要：针对含化学反应的NH_3-CO_2-H_2O弱电解质体系的复杂相平衡计算问题,以Edwards(1978)的模型为基础,采用液相内的化学平衡与汽液相平衡分步计算的思想,成功地编制了在较宽的温度和压力(100-200℃,1-20atm)范围内的计算机程序,除了可用于实际工业生产的模拟计算,还设计了图形输出块,通过计算机自动绘制汽液平衡相图,可直接与实验结果进行比较。In this paper, a practical program has been compiled to calculate the Vapor-Liquid Equilibria (VLE) of reactive weak electrolyte aqueous system. The Edwards' method (1978) was modified to calculate the chemical equilibria in liquid phase and VLE separately. GOCES_NEW can not on be used as a subroutine called by process simulation software, but can also generate the VLE diagrams used to compare with the literature experiments.
