extended wave meaning in English

其中一个属于延伸浪

The results showed that quasi - isentropic compression energy waves were produced after the impact , whose initial velocity jump , peak velocity and front ' s rise - time were all different from the general shock loading wave profiles . furthermore , the higher the impact velocity , the smaller the extended wave ' s front while the higher the peak velocity
结果表明，梯度飞片击靶后产生的是波阵面明显被展宽的准等熵压缩波，准等熵压缩波的初始速度跳跃、速度峰值和波阵面前沿的上升时间都呈现出不同于传统冲击波陡峭上升波形的特征。
Furthermore , the higher the impact velocity , the smaller the extended wave ' s front while the higher the peak velocity . at the same time , the thickness off target should also be in accord with the impact velocity . finally , experiments of quasi - isentropic loading to aluminum targets with lithium fluoride windows via w - mo - ti - mg system flier - plate with graded wave impedance , having been fabricated by sps , were performed on a two - stage light gas gun
使用sps制备出平行度好、整体致密的、 w - mo - ti - mg系准连续波阻抗梯度飞片材料，利用二级轻气炮进行了w - mo - ti - mg系波阻抗梯度飞片材料的准等熵特性的实验研究，成功实现了对带窗口材料的al靶板的准等熵压缩。
