geometric construction meaning in Chinese
几何作图；几何构造
Examples
- The geometric construction for indexable form mills
可转位成形铣刀的几何造形 - In this thesis , a well - known geometric construction called the delaunay triangulation is discussed extensively . the problem of planar mesh generation with quality bounds is considered
本文中，我们对著名的delaunay三角剖分进行详细讨论，同时对二维品质约束网格生成问题进行研究。 - In three dimensions , the basis of spatial objects is euclidean geometry , it obeys euclidean axioms . this leads directly to the question how geometric constructions , as defined by the euclidean axioms , can be represented with the finite approximations available in computer systems
在三维空间中，空间对象的定义基础是欧几里得几何，服从欧几里得公理，但利用计算机系统处理严格服从欧几里得公理的空间对象必定会带来一些问题。 - We scan photographs of tissue slices to get 2d data and then these data are classified and transfer into 3d data which are saved into database . we do geometric construction by contour connection algorithm and render the tissue using volume data based on surface . some algorithms used widely are compared in this article and implemented in the experimental system : simulating lost datum by linear interpolation , adjusting surface profile by twice bezier interpolation , dealing with some special normalized vector
通过扫描输入的人体组织的切片图象，获得组织的二维信息，再将这些二维数据经过分类和转换，把它们转换成对应的三维体数据，在数据库中保存：然后采用contourconnection算法进行几何重构，用三角面进行等值面拟合，实现基于等值面的体数据的三维图像绘制。 - In the second chapter , a wideband mimo channel model with multiple - tap was integrated according to the angle of departure of the transmitting signal and its spread angle , the angle of arrival of the receiving signal and its spread angle , power azimuth spectra , doppler spectrum and the geometric construction of antenna array both sides of transmit and receive , on the basis of full research on the theories of space - time channel model proposed in the recent literature
第二章在对最近文献中提出的一些空时信道模型理论进行详细研究的基础上，根据发射信号的离开角及其扩展角、接收信号的到达角及其扩展角、功率方位谱、多普勒谱和收发两端天线的拓扑结构，综合了一个多抽头的宽带mimo信道模型。
