摘要：

A new method of determining bulk diffusion parameters from surface segregation measurements is proposed whereby the sample temperature is increased linearly with time. The advantages of this method are discussed and a simple procedure is given which may be used to obtain the pre-exponential factor D0 and the activation energy E from a single segregation run.
