结果表明，损伤失效部位主要集中在涂层，形式包括表面磨损以及磨损引起的开裂。

The results show that the disabled parts are mostly focused on the coating, such as surface abrasion, cracking because of abrasion.

由于模具工作带附近的应力和温度均较其它部位大，从而使得模具工作带成为挤出模具失效的主要区域。

Because stress and temperature around the die land is higher than others else, the die land will become a main area of die invalidation.

星尖处的应力最大，是发动机药柱容易失效的部位。

The stress at star tip of grain was maximal, which is liable to failure.

So this is another kind of engineering, an engineering not to look more closely at how humans work but an engineering to improve their function when it's failing.

这便是另一种工程技术,它并不研究人体运作原理,而是强化某部位的功能,如果这个部位失效了的话
