These interior tensions are caused by the wedging action within the neighboring compressively stressed layers.
这些内部的拉应力是由邻近压缩应力层内的劈开作用而引起的。
As indicated in the section on simple machines, a screw ACTS with a wedging action and consists of a circular cylinder (or truncated cone) with a helical groove in it.
如在简单的机器上的区段所指出的，一个螺丝钉以一个楔住行动行事而且有圆形圆筒(或者切断了圆锥体)与一螺旋状的在它里面的凹槽。
The latter is the "water wedging" action induced by entering of water into the crack.
后者是库水进入裂缝后形成的足够强的“水楔”作用。
According to the difference of action parameter on surface, silt abrasion appearance registers as wedging, relieving, ploughing, and cutting, etc.
根据颗粒对表面作用的不同，磨损形貌表现为冲击、铲削、犁耕及切削等类型。
