According to this kind of design method , the most important thing is to confirm the radius of the two rings for lanzhou seismic array on the principle of highest signal coherence combined with lowest noise coherence 根据这种设计方式，兰州台阵的设计主要是依据各测点间地震信号的最大相干性和噪声的最小相干性的原则来确定两个同心圆的半径。
This paper made an analysis to the space structure of the tus from three layers of the villages , the internal of the village and inner part of the zhuangkuo ( tus courtyard ) , discussed the concentric circles structure of the village finally 本文时土族村落空间结构从村落与村落之间、村落内部、庄廓及其内部三个层次进行分析，最后讨论了村落的同心圆结构。
Thus , beginning with the fifteenth century , where our story finds us , paris had already outgrown the three concentric circles of walls which , from the time of julian the apostate , existed , so to speak , in germ in the grand - chatelet and the petit - chatelet 因此，我们暂且就以十五世纪来说吧，那时巴黎就已经冲破那三道同心圆的城垣了，远在叛教者朱利安时代，大堡和小堡就可以说是这三道城垣的胚胎了。
Usually , the best practical design of ims array adopt concentric circles deployment , i . e . to deploy 3 sp seismometers on the inner ring and five ones on the outer ring with near equidistance , and then with one broad - band seismometer at the center 为了达到全方位均匀监测的目的， ims台阵最实用的设计，通常采取同心圆布局方案，即在内环和外环分别基本等距地部署3个和5个子台，还有一个则落在圆心上。
In this article , the main works as follows : 1 ) talk over some basic ideas about ibr , such as , plenoptic modeling lumigraph concentric mosaics 2 ) put forward a new method about 3d animation combining reality with virtuality a . spacing matching b . lighting and shadow matching c 1 ）全光模型； 2 ）光图函数； 3 ） “同心圆拼图”方法；二、利用“虚实结合”的方法构建建筑场景，探讨了一种简便易行的建筑动画方法，并且作了有益的实践尝试。
The whole process just likes concentric circles with the cadres at the level of production team and brigade advocating the demand of farming on his own as the perpetual centre and with the development of the movement towards the direction of the left deviation , the outer circle would broaden appropriately and include the cadres at the level of community and county into its scope step by step 运动的发展就像一个同心圆，始终以生产队、大队两级有“单干”问题的干部为圆心，随着运动不断向“左”的方向发展，这个同心圆也不断地扩大，逐步将县、区级干部也包括在范围之内。
The radius of the circles are labeled as from r1 to rn ( rn is just equal to the radius of tbr ) , and these circles divided the tbr into different flow fields . the flow fields are marked from 1 to n separately , and the wall of the reactor is the flow field of no . ( n + 1 ) 1 、随机理论模型推导如图1所示，将床层截面从内向外分成以r _ 1 、 r _ 2 … … r _ n ( r _ n即为塔半径r )为半径的一系列同心圆环，并分别将r _ 1为半径的内圆和依次从内向外排列的一系列圆环定为流区1 、流区2 … …流区n 。
After the field survey , the technique and implementation group of igcsb chose dajianshan where is 18km away from lanzhou seismic station in the south - west as the array site among several backup sites , and enforced a site survey on august , 1999 . eignt suits of instruments supported by the analysis and prediction center , csb were used for the field observation , and 18 sites were deployed on two concentric circles and a beeline respectively . during the 18 days , we achieved about 3gb waveform data 1999年8月，中国地震局地球物理研究所台阵建设技术实施组经过实地考察，从几个候选阵址中选中兰州地震台西南方向18km的大尖山作为ims兰州台阵阵址，在中国地震局分析预报中心的支持下，投入了8套地震仪器以同心圆分布和直线分布方式在兰州大尖山阵址对18个测点进行了为期18天的野外观测，取得了约3gb的地震数据。
The non - local nonlinear advection possesses the duality : on one hand , compared with the linear circumstance , it increases the inward - propagation of vorticity , thus favorable to the strengthening of the typhoon ; however on the other hand , the inward - propagating vorticity destroys the concentric circle structure of the typhoon circulation , leading to the weakening of the typhoon 非局域非线性平流的作用具有两重性:一方面，与线性情况相比，可使内传涡量增加，这有利于台风增强;另一方面内传的涡量又破坏了台风环流的同心圆结构，这使台风趋于减弱。
