A new equivalent diameter and equivalent velocity based on momentum conservation were proposed. 基于动量守恒原理,提出了考虑径向流动和密度差别的同轴交叉射流的当量直径和当量速度。
It is found that the energy equivalent velocity spectra increase with the magnitude and hypocentral distance. 分析表明,水平和竖向分量能量等效速度(VEQ)谱随震级的增加和距离的减小而增加;谱的卓越周期随震级的增加而增加。
Study on equivalent velocity pulse of near-fault ground motions 近断层地震动等效速度(VEQ)脉冲研究
If equivalent velocity is considered, this equation can be extended to fit multi-interfaces reflections. 如果使用均方根速度代替单一地层速度,这个双曲线公式可以被推广到多层反射。
Considering the two effects, a simple expression of continuous function for equivalent velocity pulse time history is presented in this paper. 针对这些特点,同时考虑向前方向性效应和永久地面位移效应,提出了一种简单的、连续函数形式表达的等效速度(VEQ)脉冲模型。
