不知你发现没有,沙石铺就的道路上总是很容易自动地掀起搓衣板式的波纹,而且所出现的波纹长度和深度正好使车辆最容易受损,有的车辆甚至因此而出现车祸,是这些路面专门与在它上面行驶的车辆作对吗?行驶的车辆暂且不要抱怨,这些波纹正是车辆们自己制造出来的,而且波纹的长度和深度与车辆的速度与质量密切相关。 I do not know if you found that sand and gravel road is always easy to automatically set off a washboard wave, and the ripple length and depth appear just to make the vehicle most vulnerable, and some vehicles and even car accidents, Are these pavements specifically paired with the vehicles on it? Vehicles do not complain for a moment, these ripples are exactly what the vehicles made and the length and depth of the ripples are closely related to the speed and quality of the vehicle.
