压应力

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

腾冲火山区构造应主要为北北东—北东—北东东向，接近水平的应。

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.

精硬态切削在滚动轴承表面形的残余应,经工作应衰减后才为影响滚动接触疲劳寿命的应状态。

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.

在两种冷却方式下，不论拉应应的作用，均使组织中残余奥氏体数量减少，形貌由无应时的块状变为条状或薄膜状。
