The effect of the ions such as Cl CH3COO Na+ K+ and Ca2+ upon the phase equilibrium was simulated by Matlab, in which the UNIQUAC model put forward by Sander was extended to that is brought out by Sander is extended to the triple azeotropic system.

• 将Sander等提出的UNIQUAC模型扩展到三元共沸体系，采用Matlab软件编程，模拟了由离子Cl~-、Br~-、NO_3~-、CH_3COO~-、Li~+、Na~+、K~+和Ca~(2+)组成的16种盐对体系的影响。
