【摘要】 作者曾提出关于多体系相图计算机成图的符号函数矩阵法(SFM).现以NaClKClH2O和KClKNO3H2O在101325Pa及298.15K条件下的相图为例,用这种方法处理了简单共饱型的三元水盐体系W1W2,X1X2,m1m2相图计算机成图中的几个关键问题,结果与实验事实完全吻合

【Abstract】 SFM(Sign Function matrix) discrimination method,a simple and universal method for computerplotting of multisystem phase diagrams,has been proposed.As an extension of the application of the method to saltwater systems from mineralrock systems,the method was used in the present work to deal with some key problems in computerplotting of W1W2,X1X2,m1m2 phase diagrams of a ternary saltwater system.The worked exemples are the plotting of phase diagrams of the NaClKClH2O and KClKNO3H2O systems at 101325Pa and 298.15K.The work was performed in the following sequence:(1) Creating matrix LLXq to determine the univariant scheme about the invariant point,which needs only a simple combination of every sign function value of [ΔrGm(i)/Xq]Xc with SN,the sign function matrix of stoichiometric numbers;(2) Creating matrix SD to group all curves,which can be achieved by selection of a reference curve (Pi) and comparisons of the corresponding elements in the ith row and the ith column of LLXq;(3) Determining the variable interval of the stable part of the reference curve by comparison of the coordinate values of two points;(4) Creating matrix LPXm to determine the varible interval of the stable part of every curve by a simple combination of the results of (2) and (3).The results are consistent with experimental data.
