成双的

The slit grating is the parallel arrangement of equal width light blocking stripes. In the preset optimal view plane, the double micro polarizing structure has no superposing of the right and left images, resulting in greatly improved stereo image quality.

本发明公开的一种新的立体成像装置及其方法，其双微偏振结构在预先设计的最佳观看平面处，不存在左右图像的重叠，因此不会出现串影现象，从而大大改善了立体图像显示的质量。

The contourlet transform used in the system was constructed by dual tree complex wavelet transform followed by critically subsampled directional filter banks, sub-bands energy and standard deviations were cascaded to form feature vectors, and the similarity metric was Canberra distance. The performance of retrieval system was compared including original contourlet transform, non-subsampled contourlet transform, semi-subsampled contourlet transform and CCT under the same system structure.

该系统采用的复数轮廓波变换由双树复小波变换级联临界下采样方向滤波器构成，特征向量采用子带系数的能量和标准偏差连接而成，以Canberra距离为相似度度量标准；比较了基于同样架构的基本轮廓波变换、无下采样轮廓波变换、半下采样轮廓波变换和CCT纹理检索系统的性能。

In this article,a simplification of the entire bridge lattice into a "Plate Girder Frame" whose solution can be found by means of the force method is used instead.

在现有计算双梁桥架的内力的方法中，都是将桥式起重机的主梁简化成简支梁来计算的。

It provides a route tothe compounds which contains three functional groups, two carbon-nitrogentriple bonds and one carbon-carbon double bond. In water, metallic indiumpromotes carbon-sulfur bond coupling reaction of aromatic sulfonyl chloride withsuitable organic halides to afford sulfones. In the last chapter, metallic tin mediated allylation of aldimines with allylbromide was revealed.

第三章，我们研究了在水相介质中金属铟促进的烯丙基溴对1，1-二氰基-2-芳基乙烯的Michael加成反应，生成一个含碳碳双键和二个碳氮叁键的三官能团化合物，另外，金属铟在水介质中还可以促进芳基磺酰氯与卤代烃发生碳硫键的偶联，生成砜。

Three pairs of elite cell lines from octoploid triticalespikes were selected for screening experiment of salt-tolerant somaclonal variants under different selection pressures.

从八倍体小黑麦的单、双倍体来自同一植株的成对愈伤组织细胞系中，选择了三对在盐分浓度不同的培养基上进行变异体筛选，并测定耐盐变异体的出现频率。

Theoretical analyses show that the BRF has the maximum tuning rate when the optic axis is located on the cone with its symmetric axis being on the refracted ray and apex of 45°; and the rejection of unwanted wavelength of BRF becomes the maximum when the optic axis is in the plane which contains the refracted ray and makes the angle of 45° or 135° with respect to the incident plane.

分析表明当晶片光轴处在以折射光线为轴线、顶角为45°的圆锥面上时，双折射调谐器具有最快的波长调谐速率；当光轴位于过折射光线并与入射面成45°或135°的平面内时，调谐器抑制非所需波长的能力最强。

Several fierce flames are shot to Po. He dodged two then breaks a flowerpot. He makes accurate shot with pieces of broken flowerpot to the outlet of flames. Flaming mechnisms are operated with burning oil so they explodes one by one since the outlets have been obstructed. Later, Po seems to notice something and jumps upward all at once. As soon as he jumped, many steel spears shoot out vertically. A person with inferior martial art must be stabbed into a hedgehog shape. Po, though, shocks away all spears with a heavy both-handed slash which sends out intense collision energy and even makes a shallow pit on the ground. Po lands in the pit then runs to the wall.

只见几道猛烈的火焰向童博射去，童博闪过两道，然后打碎一个花盆，把花盆碎片向火焰射口准确的打过去，火焰机关是靠射出点燃的油，出口一但被堵，就一个个自己炸毁了，之后童博不知察觉什麼突然向上跃起，地面立刻向上垂直射出许多钢矛，要是武功稍差之人，一定被插成刺猬一样，可是童博双手持剑向下用力一劈，猛烈的剑气不但震开所有钢矛，还把地面打出个浅坑，童博落在浅坑中，一转身向墙边跑了过去
