同心圆

Most of them have concentric space structure with single-center whose disadvantages have been more and more evident with accelerative development of urbanization.

The present invention provides a direct-type backlight having: a resin sealing member including at least one resin layer, which has a light reflecting section formed on the outermost surface of the resin sealing member; an optical semiconductor element sealed by the resin sealing member; and plural circular light scattering grooves formed concentrically on at least one surface of the resin layer, wherein an area of a circle in the center and an area among the respective concentric circles are substantially the same.

本发明提供了一种直下式背光，包括：树脂密封元件，其包含有至少一个树脂层，该树脂层具有形成在所述树脂密封元件最外表面上的光反射部分；由所述树脂密封元件密封的光学半导体元件；和以同心圆形式形成在所述树脂层至少一个表面上的多个圆形光散射凹槽，其中在中心的圆的面积与在各个同心圆之间的面积大致相等。

We all know that the disk is rotating at work, and it is based on information stored in records of a series of concentric circles on its surface, each track as a concentric circle in Figure 1 we can see the track and sector The distribution of Of course, this is more than just a diagram, in-kind is much more dense than the picture!

我们都知道磁盘在工作时是转动的，它所存储的信息是按一系列同心圆记录在其表面上的，每一个同心圆称为一个磁道，在图1我们可以看到磁道和扇区的分布情况（当然，这只是个示意图而已，实物要比图中密得多！

According to the characters of debris flow and risk controlling condition in mountain towns, The concentric circle theory of geography is introduced in this paper, The concentric circle model for debris risk control in mountain towns is discussed and the effect of "concentric circle model" in hazard risk control is analyzed.

针对山区城镇泥石流危害特征及风险控制现状，引入地理学中的同心圆理论，探讨了山区城镇泥石流风险控制的"同心圆模式"，分析了"同心圆模式"中各风险控制层对灾害风险的控制机制及效应，提出城镇泥石流风险控制应遵循多层防范、逐级降低的思路，研究可为山区城镇的减灾管理提供合理的参考。

The method for the point sets selection of point Hough transform and the scan direction for image of searching the point sets were improved by using the geometrical characteristic of the concentric circles:The center of the concentric circles was obtained in the accumulative array firstly,radius was obtained by the mean of distance between the circle center and every edge points afterwards,both the circle center and the edge of the concentric circles were detected accordingly.

利用同心圆的几何特点对点Hough变换边缘点的点组选取方法和搜索点组的图像扫描方向进行了改进：首先由累加阵列确定同心圆的圆心，然后由圆心到各个有效边缘点距离的均值求出半径，从而检测出同心圆的圆心与边缘。

THIS SILVER WHEEL OF DHARMA IS INCISED WITH EIGHT TREASURES ,FOLIATE DESIGNS AND WITH THIRTEEN CONCENTRIC CIRCLES IN THE CENTRE .

这件银质千辐法*轮上錾刻八宝与瑞草文图案，中间为十三个同心圆，八宝与同心圆鎏金。

Such as the magnetic track is divided into a number of concentric circles, concentric circles in each of the tracks on It seems there have been numerous arbitrary array of small magnets, they were 0 and 1 representing the state.

这些磁粉被划分成称为磁道的若干个同心圆，在每个同心圆的磁道上就好像有无数的任意排列的小磁铁，它们分别代表着0和1的状态。

The spermatozoa are embeded in a extracellalar matrix composed of high dense fibrils matrix and flocculent and concentric vesicles similar to that in the primary spermatophore layer, but the later lack of spermotozoa. The flocculent and concentric vesicles are often seen to release their contents around the main body of spermatozoa. The spermatozoa may absorb the contents to form vesicular zone and membrane zone in sperm nucleu. The secondary spermatophore layer is distinctly subdivided into inner region and outer region. The loose outer region consists of canaliculated reticulum and large flocculent vesicles.

输精管内的精荚为管状，由精子群、精荚基质及初级精荚壁和次级精荚壁组成，初级精荚壁与精荚基质是相连续的，它们之间无明显界限，两者均由电子密度较高的纤丝状基质和絮状泡和同心圆泡组成，但后者不含精子，后者中的絮状泡和同心圆泡常在精子主体部周围释放内含物，可能与形成精子细胞核中的泡状带和膜状带有关，在交配后的雌虾，其头胸部腹面上粘着的精荚中，其基质内已不见絮状和同心圆泡，仅见稀疏的纤丝。

For the experimental results under the steady flow conditions, the scour hole and local scourdepth are comparatively small for both a eccentric and concentric non-uniform piers.Since the scouring retardation by the top of foundation and the distance between thetop of foundation and the initial bed level, the downflow intensity is reduced for theun-exposed bridge foundation (Y=+10mm).

研究结果显示於定流量作用下，不论是非同心圆或同心圆不均匀桥墩，当桥墩基础未裸露(Y=+10mm)时，由於覆土高与不均匀面之影响，而减缓向下射流之强度，因此所产生之冲刷坑大小及冲刷深度较小。
