摘要：

It is shown that the coherent potential approximation in the dilute alloy limit based on a simple model density of states leads to a very simple rule of the surface segregation in dilute binary transition metal alloys. The applicability of the model to realistic systems is discussed and predictions for the systems for which the model is applicable are derived.
