纵波

Wavelength defined,, wavelength control, transverse and longitudinal wave length , wavelength and frequency relations.

波长定义，，波长掌握，横波与纵波波长，波长与频率关系。

Different types of waves have already been considered. There was the longitudinal wave caused by the pulsating sphere, where the changes of density were propagated through the medium.

我们已经研究过几种不同的波，其中有由圆球的脉动所产生的纵波，它的密度的变化由介质传播。

In this paper the interaction problem between long longitudinal stress wave and tunnel structures with considering the plasticity of rock mass is studied by pseudo-static method.

本文用拟静法研究了考虑岩体塑性性质时长纵波与地下硐室的相互作用问题。

We know that a transverse wave will cause particles to vibrate perpendicular to the direction of the wave, and a longitudinal wave will cause them to vibrate along it.

我们知道一横波会令周遭粒子沿波的垂直方向振动，而纵波则会令它们沿波的方向振动。

In Zhenzhong Qu, longitudinal wave to the ground moving from top to bottom Britain.

在震中区，纵波使地面上下颠动。

The wave going along the spreading direction is the longitudinal wave, vibrating in one dimension space at high speed.

第一种是沿传播方向前后震动的分震动，沿传播方向传播出去就成为纵波，在一维空间中震动，传播速度最快。

The wave propagation phenomena of the longitudinal wave in the bars,the flexural and shear waves in the beams were also analysed.

分析了杆中的纵波、Timoshenko梁中弯曲波及剪切波的传播现象。

He was correct when he insisted that he was producing longitudinal waves in the natural medium.

他是正确的，他坚持说，他是生产天然培养基中的纵波。

We have undertaken an experinental study of compressional-wave velocity and It's anisotropy of mylonite and it's surrounding rocks from North-China at high pressure and temperature.

对华北地区韧性剪切带几种代表上、中、下地壳深度的糜棱岩及其围岩在高温高压条件下进行纵波速度测定及各向异性研究。

By measuring the velocity of the P wave and S wave on the three orthotropic different directions including parallel and vertical direction to the stratum of the compacted rock samples including slate, phyllite, mylonite and metasandstone, the two obvious anisotropy effects of P wave and S wave velocity are put forward.

通过对板岩、千枚岩、糜棱岩和变质砂岩等4种岩石在平行和垂直层理、板理的3个正交方向上的纵、横波波速试验，提出了致密岩石纵波波速的各向异性与横波波速的各向异性普遍存在着一致性和差异性两种特征。

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。
