由于反射的

An elliptical parabola with the same dimensions would have smaller gain by about 1 dB in relation to this analyzed rectangular, with the same efficiency, because of smaller geometric surface of the elliptic parabola.

一个同样尺寸，同样效率的椭圆形抛物线反射器，比这个长方形反射器低大约1dB的增益，这是由于椭圆形抛物面几何表面小一些。

For a typical polygonal billiard, it was found that ergodicity can be reached. However, due to the influence of the flat boundary, the diffusion rate is rather slow.

There are massive salt dome s of great thickness,which ranges from several dozen meters to 3,700 meters,in pre-salt Carboniferous carbonate reservoirs of the Pre-Caspian Basin.

由于盐丘和围岩间存在巨大的速度差异，因此导致盐体本身和下伏地层在常规地震资料中出现反射品质降低、构造失真、畸变(如盐下石炭系目的层地震反射层在盐丘部位出现构造上拉现象)，消除盐层的影响是含盐油气盆地勘探的重要课题。

The results show that chromium doped in the lattice of tin sphene substitutes Cr4+for Sn4+,leading distortion of ［SnO6］ octahedral symmentry.Hence the pigment has a broad absorption peak in the range of visible reflection spectrum, its wavelength is 520 nm. Finally,the colour develops chrome tin pink.

结果表明，由于铬的掺杂，Cr4+置换了锡榍石晶格中的Sn4+，使［SnO6］八面体变形，结果导致色剂在反射光谱的可见光520nm周围形成一条宽的吸收带，从而使釉呈玛瑙红色。

Since the forbidden bands can appear in ranges above ultra-violet frequencies,superlattice may become a good reflectorof ultraviolet light or waves of even higher frequencies.

所得结论是：极化激元呈现为能带，在禁带内电磁波不能传播，因而将完全被材料反射，由于禁带可以出现在紫外以上的频率区间，故超晶格有可能作为紫外甚至更高频率电磁波的反射器件。

When the viewpoint is changing quickly, the rendering algorithm ignores some details of the diffuse component, otherwise the scene is rendered more precisely. The Specula highlight is dependent of the viewpoint, it must be processed in real time. We present an algorithm to get rid of the area that does not contain specula highlight quickly and calculate only the area that contains the specula highlight. In order to calculate the specula reflection and refraction component, we presented a new raytracing algorithm based on the environment map transformation. The environment maps are constructed at the sample points of the scene in the preprocessing phase. We add depth information in the environment maps and generate the exact reflection and refraction intensity with the transformation of a few pixels.

对于表面光亮度漫射分量，由于它与视点无关，可以把面片按照光照细节的分布预剖分成层次结构，然后在实时漫游时根据场景变化的快慢决定绘制的细致程度；对于镜面高光分量，由于它与视点有关，必须实时处理，我们提出了一种快速高光裁剪算法，通过简单测试，去除那些不包含高光的区域，只处理包含高光的区域；对于镜面反射分量和折射分量，我们提出了一种基于环境映照变换的快速光线跟踪算法，预先在场景的离散采样点处建立环境映照，然后根据入射点的位置，把邻近采样点处的环境映照上相关象素处的可见点变换过来，求取反射分量和折射分量。

Their layered colors are created as they reflect the reddened light from the still rising Sun.

这些层次化的色彩是由于反射了正在升起的太阳发出的泛红色光芒是形成。

The big velocity difference between salt domes and surrounding rocks leads to poor reflection and distortion of salt bodies and substrata.

由于盐丘和围岩间存在巨大的速度差异，因此导致盐体本身和下伏地层在常规地震资料中出现反射品质降低、构造失真、畸变（如盐下石炭系目的层地震反射层在盐丘部位出现构造上拉现象），消除盐层的影响是含盐油气盆地勘探的重要课题。

The lack of a well-characterized in vitro model of load-induced cardiac hypertrophy has hampered further mechanistic investigation in this area, and little is known as to how mechanical load in initially converted into intracellular signals of gene regulation.

以往对心肌肥厚的实验研究基本上采用体内实验方法，然而，在体的实验研究由于受血液动力学、激素、神经反射的影响，不能恰当地反映一些因子或激素在心肌肥厚中的意义。

Because soft x ray multilayer mirrors have high reflectivity and strip filter function, their applying territories are expanded contimuously. Various fields in x ray optics grow strong demands for them.

由于软x射线多层膜反射镜具有高反射率和带通滤波的特点，x光学的各个领域对之产生了强烈的需求。

Finally, according to market conditions and market products this article paper analyzes the trends in the development of camera technology, and designs a color night vision camera.

最后根据市场情况和市面上产品的情况分析了摄像机技术的发展趋势，并设计了一款彩色夜视摄像机。

Only person height weeds and the fierce looks stone idles were there.

只有半人深的荒草和龇牙咧嘴的神像。
