折射角

Refraction regularity of extraordinary ray in uniaxial crystal with arbitrarily oriented optical axis;2. In the case of optical axis of uniaxial crystal being parallel with the incident plane, the angle of refraction of extraordinary ray are calculated by using Fermat's principle.

在单轴晶体的光轴与入射面平行的情形下用费马原理计算非寻常光光线的折射角，然后就怎样定义非寻常光作些讨论，最后在单轴晶体的光轴任意取向的普遍情形下给出计算非寻常光光线折射方向的公式。

The light is inclined to shot into from the air the hour of surface wants to take place the glint with refract, and refract the total and smaller angle of incidence in Cape, the underwater frogman tree seeing coast will become high.

光从空气斜射向水面时要发生反射和折射，且折射角总小于入射角，水下的潜水员看见岸上的树会变高。

The Snell law of refraction is:n_1,sinα=?

是金属的复折射率，因此，折射角？

The functional relation between incident angle and refractive angle of energy flow is obtained. According to this relation, we can restructure the refractive angle as negative or positive readily by selecting suitable permittivity and permeability tensors.

导出了电磁波的入射角和能流折射角之间的函数关系，根据此关系可方便地选择合适的介电张量和磁导率张量，使特定入射角所对应的折射是正或是负。

In this paper,the scheme of autonomous orbit determination of satellite is described,the extended Kalman filter algorithm based on improved numerical method is put forward.

高精度的自主定轨对探测器实现深空探测任务有着重要的意义，结合利用星光折射角的测量确定卫星轨道的自主导航方案，提出了基于数值算法改进的扩展卡尔曼滤波算法，提高了运算精度，通过仿真验证了该算法的优越性。

Finally, when regarding the component wave of irregular wave spectrum as regular wave1 and calculate the wave refraction In shallow water by Snell's law, the result is different from the result analysis by directional spectrum.

将波谱中各频率之波浪视为单一规则波，用 Snell定率计算其折射角，其结果与实测结果并不一致，表示方向波谱中各频率主方向无法利用规则波之原理以简化条件的方法求出。

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。
