摘要：表面活性物质溶液的界面张力往往随时间而变,难以测得平衡界面张力J。Kloubek曾应用经验式:1/(δH_(2)O-δt)=b/(At^(1/2))+1/A,以[1/(δH_(2)O-δt)]对1/t^(1/2)作图外推求得溶液的平衡表面张力,但所得结果仅与文献值大致相符。本文从理论上分析该经验式的由来,以及产生偏离的原因,并寻求了解决的办法。
J.Kloubek used the empirical equation l/(σH_(2)O-σt)=b/(At^(1/2))+1/-to correlate his experimental data in a 1/(σH_(2)O-σt)vs(1/t^(1/2)).It is possible to determine the static surface(interfacial)tension for solution,but the results were approximately in agreement with the literature.The article gives the theoretical derivation of the empirical equation and discusses the cause of deviation.A further investigation leads to use a extrapolating,the static surface tension is better than empirical equation.
