光线的

Cat's Eye Diopside is mainly mined in India .

猫眼状闪光或猫眼效果是光线折射的结果，在宝石表面出现单一的一条光带。

Objective: To observe the pupil diameter changes of different diopter under different rays.

目的： 观察不同的屈光度在不同光线下瞳孔直径的变化。

The bright light showed up the dirtiness of the room.

明亮的光线使房间的肮脏显现了出来。

The general formulation of double refraction or internal double reflection at a single interface is analyzed in terms of Huygens'principle and surface boundary conditions.

根据惠更斯定理和边界连续条件，分析了单个界面上的双折射与全内双反射，给出了光线方向和光波法线方向的普遍公式。

With the relations between the output of the former interface and the input of the latter, double refraction and/or double internal reflection in a crystal along two and multiple successive interfaces can be calculated.

并讨论了在晶体内沿多个面的连续双折射双反射，分析了前一界面输出量和后一界面输入量之间的联系，得到多次双折射双反射后的光线方向和光波法线方向。

The general formulation of double refraction or internal double reflection with different directions of propagation vector and wave vector in a uniaxial crystal is analyzed in terms of the Huygens principle.

并讨论了在晶体内沿多个面的连续双折射双反射，分析了前一界面输出量和后一界面输入量之间的联系，得到多次双折射双反射后的光线方向和光波法线方向。

You can maintain Drosera burmannii a number of years if you remove the flower stalks before the flowers open, keep the plants in their ideal circumstances of heat and light, and repot them after the mat of old leaves gets thick enough to interfere with new roots.

如果在每次开花前剪去花梗，并让植株维持在最佳的温度和光线，可以让宽叶毛继续生长数年。当老叶已经纠结在一起，粗到会妨碍新的跟生长时要帮它们换盆。

But in the early morning or late afternoon the sun is low in the sky.

但是，在清晨或傍晚太阳在天空中位置很低，你的身体接受了更多的光线。

And Muffat was there, eggcup in hand, making a clever use of his suspicions.

他仿佛又看见了那间道具仓库，那暗绿色的光线，杂乱无章的道具上都积满了灰尘；缪法站在那里，手里拿着蛋杯，满腹疑虑。

I disliked the dim light, and on the second day fixed, at my own expense, a more powerful electric bulb .

我不喜欢那暗淡的光线，第二天便自己掏钱买了一只瓦数高一些的电灯泡。

The split between the two groups can hardly be papered over.

This approach not only encourages a greater number of responses, but minimizes the likelihood of stale groupthink.
