查询词典 incident rays

Others began considering the virtues of a concave paraboloidal mirror as primary receptor: it had been known since Antiquity that such a mirror would bring parallel incident rays to a focus at one point.

其他人开始考虑的美德，凹抛物面反射镜作为主要受体：它已被称为自古以来这样的一面镜子，会带来平行事件射线的焦点在1点。

In summer, because the vertical incident solar rays regionmoves by the equator to the north, causes of southeast trade crossingthe line the southern hemisphere to change the southwest monsoon toinvade Northern Hemisphere, meets one another with the originalNorthern Hemisphere's Northeast Tradewind, compels crowds this airrise, the increase convection current, again because the southwestmonsoon and the Northeast Tradewind direction is different, meets oneanother often creates the undulation and the whirlpool.

在夏季，因为太阳直射区域由赤道向北移，致使南半球之东南信风越过赤道转向成西南季风侵入北半球，和原来北半球的东北信风相遇，更迫挤此空气上升，增加对流作用，再因西南季风和东北信风方向不同，相遇时常造成波动和旋涡。

In a thin spherical lens, not all rays from infinity--incident parallel to the optical axis--are united at one point.

在一个薄球面透镜，并不是所有的射线无限-突发事件平行光轴-是美国在1点。

Luneberg lens is a spherical lens which its permittivity varies with normalized radial coordinates. It is fabricated by using different homogeneous dielectric centrically layered media. The lens can focus a parallel beam of rays from any direction exactly at a point on the surface. If it is made by adding a reflecting surface "metallic cap", it is called Luneberg lens reflector. It can reflect incident wave into plane wave in incoming direction. It is usually applied in antenna, radar reflector,satellite-based, and mobile-communucation.

龙伯球透镜为一种介电系数与半径成一固定比例的球形透镜，大部分是由数层不同介电系数介电质组合而成，而其主要特性能够把入射波聚焦到球表面一点，假使在透镜表面处镀上一圆锥角金属层即为龙伯球透镜反射器，能把入射波依平面波的型态反射回原入射端，通常用於天线、雷达、卫星通讯、军事等方面。

Finally, Jones vectors for the electric fields of the incident and refracted rays are obtained.

最终给出了入射光和折射光电场矢量的琼斯矢量形式。

The ray from the plasma lamp will go through into the light pipe with little incident angle after reflection by the reflector, and then the total reflection of the ray will occur among the prismatic reflecting films. Some ray may come to the end mirror and will be reflected back, and only a little of rays pass through the prismatic reflecting films, most of the rays will go forward by the action of the bottom light extracting surface and go out to be lighting.

等离子灯球发出的光线经过反射器反射后，以很小的入射角进入到导光管，光线在棱镜反光膜管子内进行全反射，到达丙烯酸树脂管端底镜面的光线，再反射回到管子内部，只有少量的光线透过棱镜反光膜出来，最终大部分光线通过管子底部的光线提取面引出管外，传送到所需要照明的宽广区域（见图7）。

The invention comprises a free-form surface prism with three optical surfaces, and a micro-image display; the free-form surface prism is made of plastic glass materials with the refractive index greater than 1; the three free-form optical surfaces are concave surfaces, which meet one of the three surface-type equations, and the location relationship of each surface meets three condition equations; the incident angle formed between the widest-field upper edge rays emitted by an LCD and the second free-form surface meets the total reflection conditions; and an image source element is an LCD of 0.61 or 0.59 inches.

本发明包含一个具有三个光学表面的自由曲面棱镜和一个微型图像显示器，自由曲面棱镜采用折射率大于1的塑料玻璃材料，自由曲面棱镜的三个自由曲面光学表面均为凹形面，它们应满足三个面型方程之一，并且各表面的位置关系应满足三个条件方程，由LCD发出的最大视场上边缘光线在第二自由曲面上的入射角应满足全反射条件，像源元件为0.61或0.59英寸的LCD。

Based on Fermat's principle and light path function, it gets the spectral distribution of the incident rays, and it can get the ray tracing map through a matrix method.

在费马原理的基础上利用光程函数法得到入射光通过光栅后的光谱分布情况，再使用传输矩阵的计算方法构造出光谱的点列图。
