初始缺陷和强度参数为设计变量，采用一阶矩法计算单元层的失效概率。
The initial imperfection and the strength parameters are considered as random variables. Ply-level failure probability is evaluated by the first order reliability method.
危险，但是，是通过令人惊讶的成功和需求，并创建一个市场失效初始提交项目有较短的时间跨越的观念。
The danger, however, is when the initial belief that the project had a short time span is invalidated by surprising success and demand, and the creation of a market.
结果表明初始焊接阶段电极磨损速率较大，点蚀加剧了电极磨损与失效。
The results showed that electrode wear rate was higher at beginning welds than later welds; pitting building at electrode surface accelerated electrode wear and invalidation.
从压力试验，塑性失效理论和自增强处理的角度提出以同尺寸单层容器的初始屈服压力作为超压处理压力。
Initial yield pressure of monolayered cylinder with the same size was considered as the SPT pressure, based on the analysis among pressure test, plastic fault theory and self enhancement treatment.
