摘　　要：用微分电容曲线研究了１．４－丁炔二醇在镍电极上的吸附特性．实验表明，它的吸附与汞电极上的有所不同．它有一种更为平卧的吸附排布，在镍上具有中强的吸附强度，随吸附覆盖度的增加，吸附由服从Ｔｅｍｋｉｎ等温式变为服从Ｆｒｕｍｋｉｎ等温式。The adsorption of 1.4 butynediol at nickel electrode have been studied by differential capacity curves. Their differental adsorption characteristics at nickel and mercury electrodes were discovered. In comparison with adsorption layer at mercury there is a more horizontal orientation at nickel. Its adsorption belongs to a moderately strong adsorption and adsorption isotherm has a transformation from Temkin type to Frumkin type. In a definite range of potentials Gibbs free energy and interaction coefficient between adsorbed molecules were considered to be potential independent.
