On Accelerated Factor and Condition for Constant Failure Mecha nism (Ⅱ)-The Case for Failure Follows Counting Process

本文在产品失效服从计数过程时，根据加速系数的定义，详细地讨论了加速系数的性质，指出这些性质与计数过程失效机理不变条件间的本质联系。

When product failure follows a counting process, the properties of accelerated factor are discussed, based on its defination in this paper. The essential relations between these properties and the condition for constant failure mechanism are presented. And the conditions of constant failure mechanism for commonly used reliability growth model expressed by the counting process are given.
