And the phase velocity of fast wave will decrease exponentially with frequency.

快纵波的相速度随频率的增大以指数形式减小。

When P wave incidents,The P-P wave and P-SV wave created from the same point are both functions of incidence angle,and of the media above and below the interface,V p and V s they are coupled.

在P波入射时，地下同一点产生的P P波和P SV波是入射角、界面两侧纵波阻抗和横波阻抗的函数，并且两者是耦合的。

In order to resolve this problem, we bring forward a modified algorithm and apply it to pre-stack inversion of reservoir parameters (Poisson ratio, P-wave velocity and density).

本文在前人研究的基础上提出了改进的模拟退火算法，同时利用改进的算法反演了地层泊松比、纵波速度和密度。

The research results show that there is a good positive correlativity between dynamic modulus of elasticity and the longitudinal or transverse wave velocity, but there is no such positive correlativity between dynamic Poisson's ratio of the rocks and its longitudinal or transverse wave velocity.

研究结果表明，煤系岩石的动弹性模量与岩石的纵波或横波速度具有很好的正相关关系，而与泊松比不具有这种正相关关系。

The parameters of primary wave frequency spectrum derived from array acoustic logging provided the possibility to achieve this aim.

阵列声波测井的纵波频谱参数为实现这个目标提供了可能。

Based on the basic principle of reflection and transmission in the process of the propagation of logitudinal wave, this paper recounts a new theory and method for the application of pile body completeness inspection data with reflection wave method to the quantitative determination of apparent reflection coefficients and the round travelling time of reflection wave.

摘要从纵波传播过程的反射和透射的基本原理出发，介绍了反射法桩身完整性检测数据在频率域中定量确定视反射系数和反射波往返时间的一种新的理论和方法。

As the water can not be transmitted transverse wave, so seaquake felt when the sea is only the impact of longitudinal wave, when the impact is power to a certain extent on board ran aground people have feelings.

由于海水不能传播横波，因此海震时在海面上感受到仅是纵波的冲击，当冲击力量大到一定程度时，船上的人有触礁的感觉。

The theoretical analysis and experiments show that TR can focus these two kinds of wave synchronously.

理论分析和实验证明，时间反转法可以让纵波和横波同时聚焦。

The radiation en ergies from a point volume source and a radial stress source are directly proportional to ω〓, and the radiation energy from a tangential stress source is proportional to ω〓.

辐射进入地层的纵波能量约为横波能量的10％。N个单个源组成的阵列源的辐射能量是N个单个源单独辐射总能量的N倍。

As another bold hypothesis, the quark is created by curling a train of longitudinal quantum waves, in which the quantum waves are connected end to end, forming a closed recurring wave ring, namely a complete chain running in a distorted manner that is similar to the human DNA spiral structure.

这里再次大胆假设，夸克是由一个段量子纵波卷曲而成，这列量子波首尾相连，形成一个闭合的循环波环，一个扭曲运转的完整链条，类似于人类DNA的螺旋结构。

The split between the two groups can hardly be papered over.

这两个团体间的分歧难以掩饰。

This approach not only encourages a greater number of responses, but minimizes the likelihood of stale groupthink.

这种做法不仅鼓励了更多的反应，而且减少跟风的可能性。
