At these locations,thrust must be provided to back the force by the change of water flow direction.
在这些地方,由于水流方向发生改变会对管线产生不平衡推力,故需在管线上设置止推系统。
A kind of automatic measuring and classifying system for the geometry parameters of engine s thrust plate is presented.
文章给出能够同时得到发动机止推片厚度、平面度等几何参数的自动检测与分选系统的设计。
