摘　　要：用随机变量分布密度函数的干涉理论推导机械零件的极限应力和工作应力分别为不同分布密度函数时的可靠性安全系数计算公式，并将解析式绘制成便于工程设计人员使用的曲线。オy adopting the principle of interference originally related to the distribution density function of random variables, the authors of this research paper propose a formula for calculating reliability safety coefficient when the ultimate stress and the working stress of the machine parts are respectively shown as different distribution density functions. The authors also convert this formula into a diagram for the reference of the designing and engineering personnel.
