分别以吐温-20、吐温-40、吐温-60、吐温-80和吐温-85为表面活性剂，甘油为助表面活性剂，在相同的条件下，制作了棕榈仁油/甘油/吐温/水四组分体系的拟三元相图。讨论了助表面活性剂（醇）与表面活性剂的质量比（Km）及不同表面活性剂对混合体系微乳化作用的影响。结果表明，所研究的各体系中，以吐温-60所形成的微乳状液区最大。

The phase behavior of the palm-kernel oil / glycerine / tween / water four-component system is represented in a pseudo-ternary phase diagram. The influences of surfactants (tween20, tween40, tween60, tween80 and tween85) and mass ratio of co-surfactant to surfactant (km) on the microemulsification region of the systems are discussed. Results show that the maximum area of microemulsion region is achieved using tween-60 as surfactant with the km value being of 0.5.
