光线的

Antihalation Backing: A dark layer coated on or in the film to absorb light that would otherwise be reflected back into the emulsion from the base.

在胶片上或胶片中涂的一层黑色涂层，以吸收光线，否则光线会从片基反射到乳剂上。

The rays go through a series of convolutions called the conoid of Sturm.Midway between the two focal lines , the rays form a circlecalled the circle of least confusion.

7光线经过一系列的聚散形成 Sturm 光锥，在两条焦线之间，光线形成一个圆斑，称为最小弥散圆。

Light strong fish will because of ultraviolet ray excessive death too, light weak fish body have more unable to show colors also too.

光线太强鱼会因紫外线过量死亡，光线太弱鱼体的颜色又无法表现出来。

This project is to analyze the distribution of the light in the high-power laser system, it bases on principles of ray optical, use the paraxial ray trace and real ray trace , proposes a new data structure and way to simulate the light in the optical system in the computer.

本课题就是以含衍射元件的大功率激光装置中由于多次残余反射形成的鬼像为研究对象，从光线光学的基本原理出发，应用近轴光线与空间光线追迹相结合的技术路线，提出一种新型的分析方法和数据结构，开发出用于含衍射元件的高功率激光系统杂散光分析的软件。

Taking stray light in "Shenguang III" as the study subject and basing on the basic principle of geometrical optics,Applying the technological path of paraxial ray and real ray tracing,a new analytic way and data structure,which suits for the specific requirement in analysis and process of ghost images,is presented.

本课题就是以"神光-Ⅲ"激光装置中的杂散光为研究对象，针对高功率多程放大系统在鬼像分析与处理方面特殊要求，从光线光学的基本原理出发，应用近轴光线与空间光线追迹技术路线，提出一种新型的分析方法和数据结构。

On ray tracing algorithm, line-surface intersection is the basic operation. we have studied the intersection method between line and plane region, quadric surface, NURBS surface.

在光线跟踪算法方面，对精确模型下曲面的直接光线跟踪进行了尝试，提出了对平面区域、简单二次曲面及NURBS曲面直接进行光线跟踪的算法。

We now have advanced EL line and various kinds of luminous materials production and testing equipment, with a strong new product development capabilities, have access to independent development of various types of light and luminous materials more than 20 patents, of which a flexible neon light, magic neon line, Spider neon nights Network, light products have been sold in 30 countries.

我们现拥有先进的EL线及各类发光材料生产与检测设备，具备强大的新产品开发能力，已独立开发获得发光线及各类发光材料专利技术20余项，其中柔性霓虹发光线、魔术霓虹线、夜蜘蛛霓虹网发光线产品已经销售30个国家地区。

November 14, in 2009, Enlight Media in East China to promote the media conference, president of Enlight Media王长田quite proud that light the media has become the nation's largest TV production company.

11月14日到2009年，在东中国光线传媒，以促进新闻发布会，对光线传媒总裁王长田很自豪的是，光线传媒已成为全国最大的电视机生产公司。

What encumbers it most is the integration of density function along rays in field. The method presents in the paper borrowed idea from volume method of ray casting, and greatly improves calculation efficiency.

其中的计算难点是光线在流场中的密度函数积分，文中利用光线投射原理改进原有的光线积分方法，有效地提高计算效率。

But if we are trying so simulate "blueish light from the sky", then a point that is exposed to a lot of the sky will receive more light, than a point that is behind a bunch of other objects that are blocking (i.e."occluding") the skylight.

但是实际情况下，如果我们试图模拟&天空中的微蓝色光线&，那么一个位置更加暴露在天空下的点会接受到更多的光线，而一个隐藏在一堆别的物体下的点，（也就是说&被遮挡住&的点），会完全接受不到光线。

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

这两个团体间的分歧难以掩饰。

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

这种做法不仅鼓励了更多的反应，而且减少跟风的可能性。
