中文拼音 [cǎiqūbiānjiè]
采區邊界
英文
boundary of section-
The border panoramas are created by constraining viewpoint motion to arbitrary convex region of a plane, and sampling cylindrical panoramas at border of the region point by point
邊界全景圖通過限定視點在平面上任意的凸區域內運動，並且在區域的邊界上逐點采樣柱面全景圖而構成。It is different from concentric mosaics as follows. the sampling region of border panoramas can be arbitrary convex region, such as rectangle, square, triangle, circle or any other shape. and its sampling manner is sampling cylindrical panorama at border of the region point by point
它與同心拼圖（ concentricmosaics ）的不同之處在於，采樣區域可以是任意的凸區域，比如矩形、三角形、圓或者其它隨意的形狀，采樣方式是在區域的邊界上逐點采樣柱面全景圖。On the base of analysis of hydrologic geology from aquifer distribution, boundary conditions and dynamic characters etc. in the research area, the paper sums up the hydrologic geologic condition, builds up the conceptual model of groundwater resource evaluation and presents 2d calculation model, as well as numeric solution and computing flow chart. after introducing general solutions of mathematic models and implementation method of rectangular grid, the paper realizes the automatic technique of spatial dispersion rectangular grid of evaluation models based on gis. finally, the paper fulfills the integration of gis with groundwater resource evaluation models from gis - based basic management information, spatio - temporal dispersion of models, definition of subprogram and visual evaluation of parameters, as well as models simulation etc., and visualizes the results of evaluation models
論文以地下水超采?地下水降落漏斗?地面沉降現象較為嚴重的常州、武進地區作為研究評價區域，在對評價區域的含水層分佈、邊界條件和動態特徵等水文地質條件分析的基礎上，概化了其水文地質條件，構建了相應的地下水資源評價概念模型與數學模型，並給出其數值解法和相應的計算流程；論文在介紹數學模型的兩種常用數值解法和模型空間離散的矩形網格生成技術的基礎上，實現了基於gis的評價模型空間離散矩形網格的自動生成；最後，論文從基於gis的評價模型基本信息管理、模型空間時間離散方法、子程序包與模型計算參數可視化賦值、模型的擬合等方面實現了gis與評價區域的地下水資源評價模型的集成，並將模型評價結果可視化。In order to validate the feasibility of the novel algorithm, ultrawide band pulse wave is used as incident wave. computational domains are limited by absorbing boundary condition. the transformation technique from near zone to far zone is used when the sampling spot is outside of the computational domains
時域成像技術以超寬帶脈沖源作為入射波源，用吸收邊界條件來界定計算域，而當采樣點遠離計算區域時，需要通過近?遠場的轉換技術把近場等效面上的信息轉換到遠場，本文採用簡單而實用的柱面波外推法作為近?遠場的轉換方法，收到了較好的效果。So as to deal with this problem, local b - spline surface designing method with complicated trimmed boundary constraints is advanced. for two neighboring surfaces, we first trim a belt along the common boundary and then bridge a b - spline surface between these two trimmed surfaces with a smooth blending. with respect to the comer area comprised of several adjoining surfaces, a rectangular region covering the comer area is obtained by trimming operations at first, and later a local b - spline for filling the rectangular region is completed through interpolation or approximation
在兩張相鄰的曲面之間，先在其公共邊界處裁剪出一個帶狀區域，然後再採用曲面搭接的方式實現曲面之間的光滑過渡；而在鄰接曲面的公共角點處，先在該角點附近區域裁剪出一個矩形拓撲域，然後運用插值或逼近的方法，設計出一張既滿足於該區域的邊界條件同時又插值或逼近內部采樣點的b樣條曲面。A uniformly sampling algorithm of three - dimensional segmented quadrilateral boundary domain and an uniformly distributed sampling point optimized method based on force equilibrium are presented. then on basis of the above researches, the smooth b - spline surface fitting is implemented
提出了一種空間四邊界區域的均勻采樣方法以及基於力平衡原理的采樣點均勻分佈優化方法，實現了三角網格模型的重新均勻采樣和參數化。分享友人
