电子设备在规定时间内的可靠性水平是与规定的工作、环境条件有关的。测定或验证设备的可靠性指标无疑要对设备施加规定的环境应力。这就在实际工作中提出了两方面的要求:一方面希望缩短可靠性试验时间,设想通过加严试验环境应力条件来达到;另一方面,当不具备对受试设备施加规定的环境应力条件时,希望在现实的环境应力水平下通过加长试验时间来等效。本文试图提出一种综合环境应力和温度应力加权系数, The level of reliability of electronic equipment within a specified period of time is related to the specified work and environmental conditions. Determining or verifying the reliability of a device undoubtedly imposes a specified environmental stress on the device. This put forward two requirements in practical work: on the one hand, it is hoped to shorten the reliability test time, envisaged by tightening the test environment stress conditions to achieve; the other hand, when the test equipment does not have the required environmental stress conditions , It is hoped to be equivalent by lengthening the test time under realistic environmental stress levels. This paper attempts to propose a comprehensive environmental stress and temperature stress weighting coefficient,
