As well this paper makes an analysis of the calculation result, and draws the conclusion that the failure of static strength of the mechanical equipment is an infant mortality failure type.

本文还对这一计算结果作了相应的分析，得出了机械静强度失效属于早期型失效等结论。

The static test of mechanical properties suggest that the flexural strength of PE/EP is higher than pure PE.

力学性能测试表明，与纯聚乙烯相比，环氧树脂增强聚乙烯材料的弯曲强度有较大提高。
