反射角

Optimal design of rhomb-type retarder can improve achromatism according to the principle that the light arising total reflection has a phase transformation in the medium surface.

根据光在介质表面全反射时发生相变这一原理，分析了一个具有3个全内反射面的菱体型延迟器件，得出了相位延迟δ与全内反射角θ和相位延迟δ与介质折射率n的关系。

The result indicates that in the designed center of the wavelength, the retarder is not only confined within the low dispersive medium, but high-index material with higher dispersion can also obtain good achromatism, and at the same time the bigger angle of total reflection can improve achromatism of the phase retarder.

从全内反射相变方程出发，以菲涅尔菱体为例，分析了消色差相位延迟器的相位延迟量随折射率变化的光谱特性，结果表明：在所设计的中心波长处，延迟器件不仅仅局限于选择低色散的材料，色散较大的高折射率材料制作的延迟器件也可以具有良好的消色差性，且较大的全内反射角有利于改善延迟器件的消色差性。

Normal the angle of incident and the angle of reflection

认识光反射的规律，了解法线、入射角和反射角的含义。

Ii Use your diagram to calculate the angle of reflection at the point where the beam of light reflects off the floor.

使用你图解计算光的反射角在在地面的反射的点在哪。

The angle between the reflected ray and the normal is called the angle of reflection.

在反射线和法线间的角称为反射角。

The Law of Reflection states that the angle of reflection of a light ray is equal to the angle of incidence.

反射定律为光线的反射角等於入射角。

T: Yes, when a light ray is incident upon a reflecting surface, the angle of reflection is equal to the angle of incidence.

当光线射到界面上，反射角等于入射角；入射光线、反射光线与法线在同一个平面内。

Thirdly, improve the lighting tank structure, form a arc surface on the top of the tank to get more reflection surface. In this way, the angle of reflection avoids the shelter of the light tube and gets the most reflection.

三是巧妙改进光槽结构，让光槽顶部形成一个弧面，增强反射面；其形成的反射角减少了灯管的遮挡，使有效的反射量最大化。

According to dispersion relations, The relations of the incident angle, reflection angle and refraction angle equations with bicrystal parameters and wave vector are obtained respectively. The variation of the reflection angle and refraction angle with the incident angle for certain bicrystal parameters is presented by angle quations.

根据晶体的色散关系解出了入射角、反射角和折射角关于晶体参量及波矢的方程，并根据角度方程给出了在一定参量下反射角和折射角关于入射角变化的关系图，以图示的方法显示了光束在界面处的异常性质。

First, according to a phase matching condition of electromagnetic wave on the stationary boundary surface, we find the refelection and transimission angles in the front system with a static ionization front. Then using the transformations of wave vector and frequency we get the corresponding angles in the laboratory system in which the ionization front is moving at relativistic speed.

首先在波面参考系中根据电磁波在固定边界上的相位匹配条件，确定电磁波在静止电离波面上的反射角和透射角，并利用波矢和频率的相对论变换，导出了在实验室参考系中相应的反射角和透射角的表达式，最后对所得的结果作了进一步的讨论。

Means the parent directory, so this command means to execute "toolchain.sh," which is in the current directory.

代表父目录，所以这个命令就是执行当前目录下的"toolchain.sh"。

Yes,In fact,I'm on our city ream.

是的。事实上我是我们市队的。
