Several cases are presented for point contacts including single asperity, wavysurface and real engineering rough surfaces, and also for finite line contact.
计算实例模拟了点接触单峰表面，正弦表面和真实粗糙表面的弹性接触以及有限长滚子线接触等接触问题。

Add wind passing over rolling terrain and "you get the same wavy effect as on the surface of water."
加上丘陵地区起伏的风向，就产生与水面泛起的波纹相同的效应。
