摘要：

Diffusion Coefficient (DR) is one of important parameters for metal and alloy. Diffusion Coefficients of metal were determined by many methods, among them radioactive isotope tracer technique was dominant, but these determination techniques were more complicated. We had studied potentiometric stripping analysis with a globular goldfilm as -a working electrode and derived the transition stripping time equation which was verified experimentally, The equation is applied to determine diffusion coefficients of metal in globular goldfilm simply and quickly in this paper.
