1.设计一测定加压下表面张力的仪器.此仪器能免除液相在毛细管中的滞后现象及其他不平衡现象.2.测定丙酮、乙醇、苯、乙酸、乙醚、四氯化碳及水等在20℃时,1到100大气压氮压力下的表面张力.3.将Langmuir吸附公式应用至气体分子在液体表面的吸附,并解释表面张力随压力增高而下降的现象.

The surface tension of a liquid decreases when its surface adsorbs gases.If we denote the surface tension by γ,the molar quantity of the gas adsorbed per unit area by Τ2 and the chemical potential of the nitrogen between them is given by the well-known Gibbs gas by μ2,then the differential relation between them is given by the well-known Gibbs adsorption equation.
