砂石路面 meaning in English
sand-gravel surface
Examples
- The acceleration time process of road surface plainness is got by using two integral calculus of the acceleration time process which is measured by five - wheel equipments . this data is worked as the input of the road surface for theoretical calculation . the result of experiments mostly fits that of calculation , and then the multiple - acceleration power spectrum distribution of the artillery and tractor are acquired
在沥青路面、破损铺砖路和砂石路面上以不同速度进行了平稳随机激励牵引试验，用五轮仪测量得到的加速度时间历程进行两次积分的方法得到路面不平度的时间历程做为路面输入进行对应的理论计算，试验结果和计算结果基本相符，得到了火炮和牵引车多个加速度功率谱分布。
