光线的

Thus these create the beautiful displays called auroras, the northern and southern lights in the Polar Regions.

因此而创造出的美丽景象称为极光，南北极地区的特殊光线。

Effects of the polarizer is effectively ruled out and filter out the scattering of light beam.

偏光镜的特效就是有效地排除和滤除光束中的散射光线。

Use a polarizing filter to eliminate some of the reflection and increase contrast; rotate it until you have the effect you want.

或者等阳光的光线适合时再重新拍摄，使用偏振镜可去除倒影并增强画面的对比度，除非必要时，请不要旋转镜头。

Ray tracing theory is used to obtain phase and universal polynomial function of grating,and the coefficient of the polynomial function is optimized by genetic algorithm.

该方法根据光线追迹原理设计获得光栅相位和面形多项式函数通式，采用遗传算法优化面形多项式函数系数，分别设计了分束比为1：2×2、1：3×3、1：4×4的光栅分束器件；其衍射效率分别为81.83%、81.11%和74.01%；三个器件的光强均匀性分别达到0.02394、0.1838和0.1912，并用Matlab进行了仿真。

Ray tracing theory is used to obtain phase and universal polynomial function of grating, and the coefficient of the polynomial function is optimized by genetic algorithm. Several grating splitters with ratio 1:2×2, 1:3×3, 1:4×4 and diffraction efficiency 81.83%, 81.11% and 74.01% respectively are designed based on the method.

The products can refraction of prismy colors; the entire product is translucent, colorful, gives a sense of dreaming....

整个产品可以折射出不同颜色的光线，整个产品是晶莹剔透，颜色丰富，五彩斑斓，给人一种如梦如幻的感觉。

As with any projection TV room lighting is the most critical.

对所有的投影电视房间来说，光线是最关键的。

The data show that the random error is inversely proportional to the square root of ray hits in one pixel.

结果表明，随机误差和计算面上网格的划分方式无关，和各网格内光线条数的平方根成反比。

Shining a flashlight along the tops of the walls, where the beams support the floor above, I saw an－other rattler slowly moving above my head.

我打着手电筒，让光线沿着大梁支撑着上面地板的墙壁顶部搜寻着，不一会我又发现一条响尾蛇在我的头顶上方缓慢地移动着。

They are hard to tackle of open after, send out the strong ray in box, all of the inside are gold and silver jewelries.

他们费力的打开后，盒子里发出强烈的光线，里面全是金银珠宝。

But we don't care about Battlegrounds.

但我们并不在乎沙场中的显露。

Ah! don't mention it, the butcher's shop is a horror.

啊！不用提了。提到肉，真是糟透了。
