摘　　要：本文试图从二点假设出发推导一个表面张力等温式：（１）溶液的表面张力是溶剂的表面张力和溶质的表面张力按其所占表面比率的相加，（２）溶质在表面的量与在体相中的量存在一个动态平衡。由此可导出如下表面张力等温式：σ＝σ０１－ａｃ１＋ｂｃ，其中常数ａ、ｂ具有物理意义。经实验数据的验证。A surface tension isotherm has been desived on two soppositions (1) the surface tension of a solution is the sum of the surface tensions of the solvent and the solute by their rates on surface,(2) There is a dynamic equilibrium of the solute between the surface phase and the body phase of the solution.Tension isotherm to be desived is =0(1- a c c ).This surface tension isotherm was proved to be better than the Szyszkowski empirical formula in most cases
