质点速度 meaning in English

particle velocity
separator velocity

Non - uniformity of the amplifying effect and dimension of the slope are pointed out through analysis of the distribution of the stress and sonic speed in the slope . forms of slope lost stability resulted from blasting vibration are analyzed and appraising rules of slope stability are summarized by a great deal instances on coasts . based on general discussion about calculation methods of the slope stability under the effect of blasting vibration , the synthetical method , a new one , is put forward , analyzed through a sample by and pointed out which is one of most valid methods
利用波动理论，得出延期时间为nt / m时减震效果最好；在分析边坡岩体内部应力、质点速度等分布规律的基础上，指出边坡震动放大效应的不均匀性和边坡尺寸效应；结合大量滑坡实例，分析了爆破震动引起边坡失稳破坏的几种形式，总结出边坡稳定性评价准则；基于对边坡稳定性计算方法的综合分析，提出了一种综合分析方法，通过算例计算分析，证明该法计算精确度高、功能全面，是边坡动力稳定性分析的有效方法之一。
