| 摘 要： | 提出了磁致过电位面的表达式。用动电位扫描法研究了０．４Ｔ磁场下纯铁在不同温度（２５，４０，６０℃）和不同浓度的盐酸（０．０５，０．２，１ｍｏｌ／Ｌ）中的阴极极化曲线，得出与温度和盐酸浓度的关系。以水合离子作用导致双电层结构改变的观点解释了温度和盐酸浓度对的影响。

| Abstract: | A formula for magnotic-induced hydrogen evolution overpotential was proposed.Cathodic polarization curves for iron in hydrochloric acid solution of different concentrations (0.05,0.2,1 mol/L) at differeat temperstures (25,40,60℃) were measured in the presence of magnetic field of 0.4T (tesla).The dependence of on temperature and hydrochloric acid concentration was obtained. Such a relationship was interpreted from the point of view that varistion of hydrogen ion hydration caused by changes in environmeat might alter the structure of electric double layer. |
