In order to reduce water loss and soil erosion and increase the bufferingpower of soil against rain water, the cultivation crossing to mountains is adopted for hilly lands.
为了减少水土流失和增加土地对雨水的缓冲力，对于山坡地都采用横山向耕种。

Overloaded power transmission at high speed, some coupling still buffering, vibration and enhance the role of dynamic performance shaft.
在高速重载的动力传动中，有些联轴器还有缓冲、减振和提高轴系动态性能的作用。
