本文以中原油田Wen-33-26井的长源距声波全波列资料为例，将所测得的井下"横波"速度当作瑞利波速度处理，求得的泊松比和杨氏弹性模量值更为合理。

The techniques of using S-wave response to investigate fractured anisotropy medium have achieved good results in practical application. However, these techniques are very complex and expensive, and then limited their application. Whenas various P-wave attributes are effectively preserved by accurate P-wave acquisition and processing techniques, thus it creates a beneficial condition to detect fracture using P-wave data.

利用横波响应进行裂缝性各向异性介质的检测在实际应用中取得了很好的效果，但技术复杂、成本较高使该方法的广泛使用受到限制，而纵波资料采集和处理技术的精细有效保持了纵波的各种属性，这为直接利用纵波资料进行裂缝检测创造了条件。

In the context of a system of barotropic shallow-water equations and Boussinesq approximate equations for two-dimensional meso-scale transversal wave disturbance in zonally sheared base flow, study is performed of the physical process of the meso disturbance propagation along the flow, indicating that such vortex Rossby waves are separated into two kinds. The first kind VRW is produced owing to the second-order horizontal shear in the flow or due to the meridional change in vertical vorticity of the flow, i.

Normally the shear velocity is about half of the compressional velocity.

And continuous measurements of compressional velocity and shear velocity were made in the course of displacing.

由于疏松砂岩声波纵、横波速度的影响因素较多，因此有必要对各影响因素进行定量研究。

In this paper,by numerical calculation, the effect of gas saturation on dispersion of model waves,excited spectrum of compressional wave and shear wave and full wave of acoustic logs in cased boreholl are discussed.

We investigated the receiver functions in a horizontally-layered medium with arbitrary oriented hexagonally symmetric anisotropy, and discussed the phenomenon of shear-wave splitting and energy deviation in an anisotropic medium. The anisotropic structure yields patterns of receiver function amplitudes and arrival times on both the radial and transverse components that are a systematic function of source-receiver back azimuth. We also investigated the influence of varying anisotropy parameters, e.g.

There was the jellylike medium in which the transverse wave spread. A deformation of the jelly, caused by the rotation of the sphere, moved through the medium.

又有一种胶状的介质，横波就是在这种介质中传播的，由于圆球的转动而引起球面上的胶状物的形变，这种形变在介质中向外传播。

With Death guitarist Schuldiner adopting vocal duties, the band made a major impact on the scene.

随着死亡的吉他手Schuldiner接受主唱的职务，乐队在现实中树立了重要的影响。

But he could still end up breakfasting on Swiss-government issue muesli because all six are accused of nicking around 45 million pounds they should have paid to FIFA.

不过他最后仍有可能沦为瑞士政府&议事餐桌&上的一道早餐，因为这所有六个人都被指控把本应支付给国际足联的大约4500万英镑骗了个精光。
