As the rotor turns clockwise the charge is sealed off and compression begins . 当转子顺时针方向转动时，送进的气团就被封闭，并开始压缩。
The only little change that the face ever showed resided in the two compressions or dints . 这面孔上所仅有的小变动全在这两个凹处或瘪处。
Faults can be ranged into two principal types which are caused by either tension or compression . 断层可分为两种主要类型，即张力断层和挤压断层。
The development of high-pressure reforming was a major contributor to reducing the compression load . 高压转化对减少压缩的负荷是一个主要的贡献。
Then diesel fuel oil is injected or sprayed into the cylinder at the end of the compression stroke . 然后在压缩冲程即将结束时，柴油燃料被喷射或被喷雾进入气缸。
This effect is due to the high radial compression produced by the external forces acting at the supports . 此种效应是由于作用在支点的外力所产生的高度径向压缩而引起的。
They can be divided into two classes, those which are castable and those which must be processed by extrusion or compression molding . 它们可分为两类：可浇铸的和必须由挤压或模压加工的。
The regions of greatest metal enhancement for a given star-forming frequency apparently suffer the greatest compression . 对于一定的恒星形成频率，金属加浓最大的区域显然受到了最大的压缩。
This stress, causing breakage, will be a tension since concretes are from 9 to 11 times as strong in compression as in tension . 由于混凝土的抗压强度为其抗拉强度的9到11倍，引起折断的应力是拉应力。
