摘　　要：分析了元件退化的概率分布,认为元件和系统在安全失效前是一个随时间变化的连续退化过程,提出了结构可靠性的动态强度干涉理论。对于几种常见的强度与应力分布,给出了可靠性评定方法。The intensity of a product is regard as the degradation process during the whole product life,and as the confrontation process with the stress imposed on the product.Dynamic interfering strength theory proposed for structural reliability,the model for a element or a system in a continuous degenerate procedure varying with time t are constructed.A method of reliability evaluations is given for a kind of common sight strength and stress distribution

关 键 词：结构可靠性 动态干涉模型 强度 应力 退化
