| 摘 要： | 通过对添加混合添加剂后溴化锂（LiBr）水溶液表面张力的测试表明,添加混合添加剂后溶液的表面张力与单独添加异辛醇（C8H18O）后的表面张力接近;在LiBr溶液中添加分散剂和两种表面活性剂时,其表面张力一直低于单独添加一种表面活性剂时的表面张力;在纳米LiBr溶液中添加分散剂和两种表面活性剂可改变溶液表面张力的分段点,并且分散剂对溶液的稳定性有极大促进作用,但表面张力稳定值没有改变.

| Abstract: | The experimental result shows that the surface tension of LIBr solution with compound surfactants is near to the one that makes solution tension smaller. When dispersant and two kinds of surface active agent are added in the lithium bromide solution the surface tension is lower than that of adding a surfactant. Dispersant and two kinds of surface active agent are added in the lithium bromide solution and the segmentation point of the surface tension of solution can be changed and dispersant has great promoting effect on the stability of the solution, hut stable surface tension values have not changed. |
