摘　　要：采用圆环法对不同浓度的甲醇溶液、乙醇溶液、正丙醇溶液、正丁醇溶液的表面张力进行测定,并通过对溶液密度、铂丝半径和铂丝环半径的修正,研究几种醇溶液表面张力与浓度及烷基链长的变化情况,从而分析醇溶液表面张力变化情况与溶度和烷基键长的关系。Surface tension of different concentrations of methanol, ethanol, propanol, butanol were measured by using ring method, after the density of the solution, platinum wire radius and platinum wire ring radius was amendated, the relationship between surface tension and alcohol concentration and alkyl chain length were studied, to analyze changes in alcohol solution surface concentration and the concentration and alkyl chain length relationship.
