光线的

Yet before the floating impress of the wood could clear itself , suddenly the gladsome light leaped over hill and valley , casting amber , blue , and purple , and a tint of rich red rose ; according to the scene they lit on , and the curtain flung around ; yet all alike dispelling fear and the cloven hoof of darkness , all on the wings of hope advancing , and proclaiming ,"God is here!"

然而，在树林那流动的景色逝去之前，欢悦的晨光突然跃出了峰峦和山谷，光线所及，把照到的地方和周围的森林分别染成青色、紫色、琥珀色和富丽的红玫瑰色。光线照到哪里，那里就如同一幅幕布被掀开。而所有的一切都同样在驱散恐惧和黑暗的魔影；所有的一切都展开希望的翅膀，向前飞翔，并大声宣告："上帝在这里！"

The traditional algorithm of Volume Rendering is Ray-Casting, not a proper algorithm for the large 3-D seismic data, referring some improved method and considering the characteristic of seismic data, a new fast Ray-Casting algorithm of oriented image space and negative-view transform was brought forward. As a result, this algorithm excels the traditional obviously by speed with image quality in experiment.

体绘制的传统算法是光线投射法，由于地震数据量大而绘制速度太慢，本文在借鉴一些改进算法的基础上，结合地震数据的特点，提出了一种基于图像空间的逆视变换的加速光线投射算法，实验结果表明该算法在保证相同图像效果的同时，具有明显的速度优势。

In view of the facts that traditional graphical construction has less pertinence to stray light and tracing different incidence angle rays is fatiguesome and more likely to omit some rays, we proposed a reverse ray-trace method based on the ray reversibility. According to the method, a dot-matrix source was set at the image plane. Each dot emitted rays to fully cover the system aperture. A detector surface, large enough to receive all possible rays from the source, was set at object plane.

针对传统作图法设计遮光罩的针对性不强，且追迹不同入射角的光线繁琐、容易遗漏的问题，本文提出一种逆向追迹法，依据光的可逆性，在像面处设置点阵面光源，每一点都发出充满系统孔径的光束，在物面设置足够大的探测面，使之有充足的余量记录所有到达物方的光线，利用该方法可以在探测面上直观地区分出非成像杂散光。

From the level of science, the light we saw is the reflection on objects, and that are not the objects themselves. The space that we apperceived from the vision is the result of the interaction between the light and objects, therefore, there is some internal relationship between the light and objects, which means there is correspondence between them.

从科学意义上讲，我们看到的是光线在实体上的反射，而非实体本身，我们视觉感知的空间是光线与实体相互作用的结果，因此光与实体存在着某种内在的联系，也就是说，光与实体存在着对应性。

The two lamps on the chimney piece, which had shades of rose-colored lace, cast a feeble light over them while on scattered pieces of furniture there burned but three other lamps, so that the great drawing room remained in soft shadow.

壁炉上的两盏灯，罩着粉红色的灯罩，发出微弱的光线，把她们照亮；在远一点的几件家具上，只有三盏灯，宽敞的客厅沉浸在暗淡而柔和的光线里。

The second-order post-Newtonian(2PX) equations of light ray have to be discussed under the recent extension of the DSX scheme which was founded in early 1990 s to discuss a complete first-order post-Newtonian celestial mechanics for N arbitrarily composed and shaped, rotating deformable bodies.

近来相继提出一系列的空间天体测量计划，要求考虑在多参考系中二阶后牛顿部分对光线传播的贡献，也就是说，必须讨论在最近完成的扩展的DSX体系下的二阶后牛顿(2PN)光线方程。

Meanwhile, with the highly efficient implementation of the industrialized production process, Enlight Media has ranked top in the following areas encompassing program development, production, package, distribution, advertising, and value-added services, in order to enlarge its produce scale, as well as, to ensure the future sustainable growth of its traditional business on television and entertainment activities.

然而，在树林那流动的景色逝去之前，欢悦的晨光突然跃出了峰峦和山谷，光线所及，把照到的地方和周围的森林分别染成青色，紫色，琥珀色和富丽的红玫瑰色。光线照到哪里，那里就如同一幅幕布被掀开。

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。
