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

腾冲火山区构造应力场主要为北北东—北东—北东东向，接近水平的压应力场。

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.

超精硬态切削在承表面形的残余压应力,经工作应力衰减后才为影响接触疲劳寿命的应力状态。

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.

在两种冷下，不论拉应力还是压应力的作用，均使组织中残余奥氏体数量减少，形貌由无应力时的块状变为条状或薄膜状。
