Our result suggests that the very low Pn velocity beneath the southcentral Tien Shan is caused by high temperatures produced by heating from mantle upwelling, and that this heat has been conducted up into the crust, inducing a ductile rheology that prevents significant seismic activity.

这一现象说明地幔上涌引起高温极大地降低了岩石层地幔的强度，并以热传导的方式进入地壳使其失去地震破裂强度而发生韧性变形。

There is a clear correlation between seismic activity and Pn velocity variation. Most earthquakes are concentrated in the northcentral Tien Shan with high Pn velocities, while almost no earthquakes located in the southcentral Tien Shan with very low Pn velocities.

Pn波速度的变化与地震分布有着密切的对应关系：地震大都发生在中天山北部Pn波高速区上方，而南部的Pn波低速区上方几乎没有地震。

The experiment shows that,with the change of silastic/ ethoxyline ratio (weight ratioε) in the mixed material,the velocity changes in 2600～

实验表明，混合材料中硅橡胶与环氧树脂的量之比不同，速度可在2600～950 m/s之间变化。

Fermat saw K as'being proportional to the reciprocal of the velocity of propagation.

Fermat 认为 K 为与传播速度互为倒数的比例系数。

Therefore, although the source of light is rigidly connected with my G.S., the velocity of light will not be the same in all directions.

因此虽则光源是严密地关联于我的坐标系，但各个方向上的光速却不会一样。

Using tools from dynamical system theory, such as phase space diagrams, Frequency analysis, Poincare sections and the calculation of statistical quantity of chaos: the correlation dimension, Reni entropy, Laypunov exponent and so on, the different solutions to the Navier-Stokes equations at different values of the Reynolds number have been identified and characterized through reconstructing the phase space of velocity time series by means of time delay and dimension embeding.

通过时间延迟和维数的嵌入对速度时间序列重构相空间，利用非线性动力系统理论方法诸如相空间分析，频谱分析，Poincare映射，以及通过对混沌统计量：关联维数，Reni熵，Laypunov指数等计算，对不同雷诺数N-S方程解的特征作了分辨。

Firstly, the principles of Rayleigh wave, which are the foundations of Rayleighwave velocity inversion, are introduced.

本文首先介绍了瑞雷波的理论基础，这也是瑞雷波速度反演的基础。

The Heisenberg Uncertainty Principle states that you cannot know a subatomic particle's exact position and its exact direction and velocity at the same time.

根据海森堡不确定原则，你无法同时知道亚原子粒子的确切位置及其确切方向和速度。
