摘　　要：在293 K^328 K的温度范围内,用Devanathan-Stachurski电池装置测定了氢在A3、08F、16MnR和20G钢中的氢渗透曲线,求得氢扩散系数与温度之间的阿仑尼乌斯方程,为监测钢在使用中氢的积累提供基本参数.The curves of hydrogen permeation in steels of A3, 08F, 16MnR and 20G were determined at temperatures between 293 K to 328 K by Devanathan-Stachurski cell. The Arrhenius equations of hydrogen diffusion coefficient versus temperature were found out. The equations may provide important fundamental parameters for monitoring the susceptivity of hydrogen induced crack while the steels are used in various industrial environments.
