It is difficult to be simulated and analyzed due to the excessive surfaces, complex structure and locomotory parts in zoom lens. All the transmission planes taken as the partial reflection and partial transmission planes were simulated with ASAP（advanced system analysis program）and the stray rays on "dangerous surfaces" which easily generate the ghost images in zoom lens were analyzed. Based on it, the zoom lens was optimized and the quality of image was improved by changing the curvature and refractive index of the second reflection planes.

利用ASAP软件模拟每个透射面作为部分透射、部分反射的表面，对变焦光学系统非轴上光进行分析，模拟出变焦系统的光学元件表面和光机内壁，实行实际光线追迹，然后以像面为研究对象，进一步实施实际光线追迹，模拟出全部散射光在像面上的能量分布，找出鬼像形成的原因，并在此基础上通过改变二次反射所在面的曲率或改变所在面的折射率两种方法对变焦光学系统进行优化，减小鬼点数目，以提高系统的成像质量。

This paper listed a great number of records of dinoflagellate cysts with transapical ar-chaeopyte suture in marine and nonmarine deposits and pointed out that the cysts with this structure could be divided into two types which represented respectively two branches of later Cretaceous from marine pyrrophyta.One branch was represented by Palaeoperidi-nium with bipesioid type of reflection plate;the other was represented by Saeptodinium with bipesioid or cinctioid type of reflection plate.

摘 要：本文列举了大量具过顶古口缝的沟鞭藻囊孢在海相和非海相沉积中的记录，指出具这一构造的沟鞭藻囊孢可以细分成两个亚类，分别代表晚白垩世从海相多甲藻类家族中分化出的两个分支：一支以Palaeoperidinium为代表，具bipesioid型反映板式；另一支以Saeptodinium为代表，具bipesioid或cinctioid型反映板式。

However, at high frequencies pinnae can conceal the shoulder reflection so that the shoulder reflection below 3.0 kHz is available as a stable localization information.

因此，3.0 kHz以下的肩部反射能够成为一个稳定的声源定位因素。

Analyses reveal that shoulder reflection is irrelevant to clothing below 3.0 kHz, while without pinnae clothing has some influence on should reflection and HRTF above 5.0 kHz.

实验结果表明，在3.0 kHz以下肩部反射声几乎与衣服无关；而无耳廓时，不同的衣服对5.0 kHz以上的肩部反射声以及头相关传输函数有一定的影响，但耳廓的存在会掩盖肩部反射的高频部分。

Based on the seismic data obtained in deepwater area of northern South China Sea in recent years, the development of ancient Miocene reef was analyzed. The seismographic result shows typical reef feature in the Xisha uplift, such as the mound, high amplitude, middle frequency, middle continuity, and chaotic reflection. Some reef-like reflection was found in the Miocene Meishan Formation in Beijiao area of Qiongdongnan Basin.

中文摘要：基于近些年南海北部深水区采集的地震资料，对南海北部深水区中新世生物礁发育特点进行分析、对比和研究，认为西沙隆起地区发育典型的生物礁，具有丘状反射、强振幅、中频、中连和杂乱地震相，发现琼东南盆地北礁地区在中新世梅山组也有似礁相发育。

Its specula reflection weakened while scattering reflection reinforced.

此时其镜面反射能力减弱，漫反射能力增强。

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。

In the study of the water oxygen resume, start off the mechanism of the atmosphere oxygen resume, the paper first poses the atmosphere oxygen resume equation and oxygen resume coefficent calculation formulation of the static state water. The number of the progressing of the Blak-phelps equation is made certain, and the atmosphere oxygen resume equation and coefficent are ensured in both conditions of considering the floor reflection and unconsidering the floor reflection.
