查询词典 reflection grating

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.

在对湖库水体复氧研究中，从大气复氧的机理出发，首先提出静态水体的大气复氧方程和大气复氧系数计算公式，其中对Blak-phelps方程级数项项数的确定，不考虑底部反射的大气复氧方程和考虑底部反射的大气复氧这三个问题进行了深入分析，得出相应的结果。

Xu Zhou sprouted a great deal of Han Dynasty portrait stone, for our country four big fellow portrait the stone sprout one of the concentration grounds, its topic is erudite, contents abundant, the topic which has reflection reality the life has the traffic the line, to Bo ratio force, dance joy stunt, face a guest to entertain guest, kitchen banquet feast, building person, male Geng female knit etc.;The contents which has reflection myth the story has the gold in the Fu Xi, female Wa, burning emperor, Emperor Huang, east princes and dukes, west Wang2 Mu3, day black, moon in month etc., the pattern which has already meant good omen good luck has a green dragon, woman without pubic hair, Vinaceous Rosefinch, the Xuan force, Qi Lin, nine tail foxes, two dragons to wear Bi, ten words to wear wreath etc..

徐州出土了大量的汉代画像石，为我国四大汉画像石出土集中地之一，其题材广博、内容丰富，有反映现实生活的题材有车马出行、对博比武、舞乐杂技、迎宾待客、庖厨宴饮、建筑人物、男耕女织等；有反映神话故事的内容有伏羲、女娲、炎帝、黄帝、东王公、西王母、日中金乌、月中玉兔等，有表示祥瑞吉祥的图案有青龙、白虎、朱雀、玄武、麒麟、九尾狐、二龙穿璧、十字穿环等。

Some related specilist point out ,the modernists dependent upon mobile phone more and more , the mobile phone is not the same as the common ionization radiation ,the wavelength of electronmagnetic wave emanated by the mobile phone is 900MHz to 1800MHz. Although, the DNA has not been damaged by it to certain degree yet , but this microwave can radiate to the depth of encephalic 4 to 6cm . stimulate the water molecules and cells moving ,result in the temperature of corresponding tissue raising 0.1c, induce the fever reflection such as the headache,disfunction of blood supply in brain, cauterized feeling on the skin of face ,ear as well as the skin around the ear etc .also induce the non-fever reflection such as the changing of sleeping style ,raising blood pressureand and disfunction of recognization etc.

0有关专家指出，现代人越来越离不开手机，但不同于普通的电离辐射，手机发射的电磁波波长为900MHz--1800MHz，虽然尚没有达到损伤DNA的程度，但此种微波可以辐射深度达颅内4--6cm，刺激水分子和细胞发生运动，导致相应组织温度上升0.1c，引发如头痛，脑供血障碍，面部皮肤烧灼感及耳部及耳周皮肤烧灼感等热反应，而且可以引起诸如睡眠方式的改变，血压升高，认知功能障碍等非热反应。
