By analyzing the interdependence between the operating stress f0und in RET and the stress in actual operation environment,the formu／a for reliable probability was deduced based on interference mode1.Then an example was given to explain this approach's feasibility.RET could improve the reliability of products by improving the quality of design and manufacturing process.By using the interference model and the deuced formula,two ways of improving the reliability of products were analyzed.

应力强度干涉模型根据产品的应力和强度相互关系分析产品的失效，在传统可靠性工程中主要应用于机械产品可靠性分析，本文将这一模型理论运用于可靠性强化试验中，推导出了利用，强化试验数据计算产品可靠度的相关公式，将定力量分析引入RET中，解决了RET无法进行定量分析的问题。

The public has gotten such a uniform message that stress is always harmful," says Janet DiPietro , a developmental psychologist at Johns Hopkins University."And that's too bad, because most people do their best under mild to moderate stress.
