The tectonic stress field in Tengchong volcano areas is oriented as NNE-NE-NEE, nearing horizontal compr essive stress field.

腾冲火山区构造主要为北北东—北东—北东东向，接近水平的压。

The residual stress formed on the surface of rolling bearing in superfinish hard turning will influence the fatigue life of rolling contacting after stress decay.

超精硬态切削在滚动轴承表面成的残余压,经工作衰减后才成为影响滚动接触疲劳寿命的状态。

During two cooling methods, whether tension stress or compression stress, the retained austenite in steel reduced with stress increasing, had become from massive to streak or filminess.

在却方式下，不论拉还是压的作用，均使组织中残余奥氏体数量减少，貌由无时的块状变为条状或薄膜状。
