【Abstract】 Taking the W 1 W 2, m 1 m 2 and X 1 X 2qd diagrams of the complex ternary systems Li +,K +∥SO 2- 4 H 2O at 298.15K and 101kPa as an example, the sign function matrix (SFM) method is employed to discriminate the variable interval of each stable univariant curve and the stability of each invariant point in the phase diagrams. The results are in good accordance with the experimental ones, which means a very good solution to the important problems involved in the prediction and computer plotting of the phase diagrams of salt water systems.更多还原
