摘要：

In this paper we adopt the four atom-vacancy exchange frequency model for diffusion in an ordered alloy and deduce a set of exact relations (sum rule) among the phenomenological coefficients. The relations are expected to be approximately true for the Ising alloy model when the jump frequencies are replaced by ensemble averaged quantities.
