折射的

Critical angle of refraction - semi-circular cylindrical mobile light source, the incident angle change the size of refraction angle to change at this time, when the refraction angle = 90 degrees, which is critical at this time angle of incidence angle, the critical angle of water at 40 degrees large about anything mobile source of water in the water screen that is a reflection of light, a phenomenon that total reflection.

光折射的临界角定义：光折射角=90度时，入射角即为临界角，按二方法，将半导体激光光源去掉铁夹，吸附在右下角的铁板上入射光对准中心，即产生折射光线，沿半圆形柱面移动光源，改变入射角的大小，这时折射角也改变，当折射角=90度时，这时入射角即为临界角，水的临界角大的在40度左右，再做移动光源在水中的水屏即出现反射光线，这种现象称全反射。

The results show that when the linear birefringence is small, the linear birefringence of the bulk glass can be effectively measured by the methods reported in this paper.

The law of refraction, discovered first empirically by Willebrord SNELL, then subsequently derived formally by Descartes and Fermat, states that sin r = K sin i, where i is called the angle of incidence, the angle between the incident ray and the normal to the refracting surface.

折射的轨律，首先被 Willebrord SNELL 靠经验发现，接着后来正式被笛卡尔和 Fermat 认定，规定 sin r = K sin i ，这里 i 被称作入射角，入射光线和法线到折射平面之间的夹角。

Therefore,it is of great importance to measure the linear birefringence inside the optical current sensing head for the property enhancement of the optical current sensors.

线性双折射是光学电流传感头的重要光学参量之一，会明显影响光学电流传感器的性能，因此测量光学传感头内线性双折射的大小对于提高光学电流传感器的性能有重要意义。

These options control the number of times a ray can reflect/refract before it is removed from further calculations.

这些选项控制光线可以反射/折射的次数，在进一步计算之前这些反射/折射就要计算完成。

Using the nature of endocone refraction and external cone refraction and the corresponding position relation on the light wave plane, the expressions of the cone-apex angles of endocone refraction and external cone refraction are deduced.

以此为基础，借助内锥折射和外锥折射的性质及对应光波面上的位置关系，推导了内锥折射锥顶角和外锥折射锥项角的表达式。

In VRay's material the amount of scattering is controlled by the refraction Glossiness parameter.

折射的一个可供变的地方叫折射光泽度（又叫模糊折射或毛玻璃折射）。

A brief introduction to domestic research of negative refracting materials is given, and two possible routes to negative refracting via functional polymeric materials are suggested.

本文还简要介绍了国内负折射材料的研究现状，提出了利用高分子功能材料实现负折射的两种可能的途径。

Based on the technique of PIV,We calculated the light intensity of the bubble interface and discovered that the intensities of lighr reflected or refracted twice succeedingly abide by the rules of geometric series , and the light will disappear after reflecting or refracting 4 times by the bubbles.

基于粒子成像测速的流体可视化技术，根据菲涅耳公式计算了入射到水中气泡界面的光强，得出点光源连续两次反射或折射的光强具有等比数列的规律，光线在气泡界面反射、折射4次就变成完全偏振光且光线几乎消失。

On the special structure of the Lower Latitude Meridian Circle and the practice of determining astronomical refraction in Yunnan observatory,a new method for improving the correction accuracy of the atmo- spheric refraction delay is proposed:the determined data of the astronomical atmospheric refraction values with different azimuths are utilized to find the refractivity and the param- eters of mapping functions for modeling the atmospheric refraction delay correction,which changes with the observing stations and azimuths.

根据云南天文台低纬子午环的特殊结构，和测定大气折射的实践，提出了提高折射延迟改正精度的新方法，即：利用各观测站不同方位从天顶附近直到低地平高度角的天文大气折射实测数据，求解得到折射率差和映射函数的参数，从而建立随测站和随方位而异的大气折射延迟改正模型。

This brought fixed cost, but it also is meant at the same time use a source to won't make you singlehanded assume a problem.

这带来了一定的成本，但它同时也意味着使用开源不会让你独力承担问题。
