摘　　要：将随机理论和概率论及统计原理的相关知识运用于可靠性研究之中，获得了复杂应力状态下的可靠度理论计算公式。文中给出了按传统假设思想和本文推导的理论计算公式二者分别求得的可靠度，并进行了比较。In this paper,the stochastic theory and the relative knowledge of probability statistics are applied to the statical strength reliability analysis. The theoretical computing formula of reliability on the complex stress condition is worked out. The computative results for the nonekey joint by the traditional method and by the method presented in this paper are compared.
