压应力

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

腾冲火山区构造场主要为北北东—北东—北东东向，近水平的压场。

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.

超精硬态切削在轴承表面形的残余压,经工作减后才为影响触疲劳寿命的状态。

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.

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