Seismic anisotropy can be studied by four basic seismic wave behaviors, e.g, direction-dependent travel time anomalies, shear-wave birefringence, surface-wave scattering, and direction-dependent conversion of compressional waves to shear waves.

目前人们利用4种基本的地震波现象研究地震各向异性，如横波双折射、面波散射、与传播方向有关的走时异常和PS转换波震相。

On the other hand, the use of Fresnel lenses has been the main stream for optical concentrators because of its flexibility.

The density, refractive index and molar refraction of glasses,and their relationship with composition had been measured.

测量了玻璃样品的密度，折射率和摩尔折射度，并分析了它们和玻璃组分的关系。

Limit the reflections or refractions to a certain distance,so you can skip objects that are very far away in the scene.

将反射或折射限制在一定的距离内，这样你可以跳过场景中非常远的对象。

In Chapter 1, following the history of PhCs research on the dispersion characteristic, we introduce two important concepts involved in the thesis: negative refractions and designed surface plasmons.

第一章，我们首先引入光子晶体的概念，然后以时间为线索重点介绍了光子晶体色散方面的研究状况，主要包括负折射现象和人造表面等离子体波。

Frequency stabilization laser based on transverse Zeeman effect provides several characters such as high stabilization frequency.

基于横向塞曼效应的稳频激光器，频率稳定度高，抗干扰能力强，输出功率大，差拍信号频率低、易于接收和处理，可直接输出相干性和偏振度都很好的线偏振光，便于测量偏振、双折射等物理量。

Such distinct constitutive parameters have brought the medium several quite unique electromagnetic properties, such as negative refraction, reversed Doppler effect, reversed Cerenkov radiation, etc.

其独特的本构参数给予了这种介质独特的电磁特性，比如负折射、逆多普勒效应、逆？

Even on Mauna Kea, Keck has to deal with the distortion caused by Earth's gaseous atmosphere, which is the greatest enemy to ground-based telescopes.
