摘要：

A computer program was generated to calculate the surface tension of binary liquid alloys. The results for Pb-Sn and Fe-Si alloys are presented. By applying the simplest form of the quasi-chemical theory to the surface monolayer and directly using experimental values of the bulk activities, one can calculate alloy surface tensions without the use of any adjustable parameters. The surface coordination number and surface monolayer area have been taken as constants independent of composition. The theory has yielded excellent results for binary alloys exhibiting positive and negative deviations from Raoult's Law.
