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.

超精硬切削滚动轴承表面成的残余压应力,经工作应力衰减后才成影响滚动接触疲劳寿命的应力。

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.

两种冷却方式下，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，貌由无应力时的块变条或薄膜。
