查询词典 deduct points

The basic idea is to set a continuous solution of the region with a finite number of discrete points instead of a grid consisting of, these discrete points called grid nodes the solution of a continuous area on a given function of continuous variables used in the definition of discrete grid variable function approximation the original equation and boundary conditions in the micro-business operators to approximate differential, integral with the points and to approximate, so the original differential equations and boundary conditions are replaced by algebraic equations near Side, that is, finite difference equations , solve this equation group can get the original problem in discrete points on the approximate solution.

基本思想是把连续的定解区域用有限个离散点构成的网格来代替，这些离散点称作网格的节点；把连续定解区域上的连续变量的函数用在网格上定义的离散变量函数来近似；把原方程和定解条件中的微商用差商来近似，积分用积分和来近似，于是原微分方程和定解条件就近似地代之以代数方程组，即有限差分方程组，解此方程组就可以得到原问题在离散点上的近似解。

Furthermore,we present the method for designing quadratic Bezier developable surface:give four corner points of developable surface and two free designing parameters,the other two control vertexes are on the line connecting the linear interpolation point between the first two control vertexes and the linear interpolation point between the last two control vertexes,and they are the linear interpolation points between these two linear interpolation points respectively,namely,these four linear interpolation points are colinear.

提出了二次Bézier可展曲面的设计方法：给定可展曲面的4个角点a0、b0、a2、b2和两个自由设计参数？姿、？滋，则待求的2个控制顶点a1、b1是在前2个控制顶点a0、b0的线性插值点a*与后2个控制顶点a2、b2的线性插值点b*的连线上，并且也是a*、b*这2个线性插值点的线性插值，即这4点a*、a1、b1、b*共线。

After disinfection and medical activities before, samples were taken from three points in a diagonal of a relatively closed space with area not more than 30 square meters. In general, one point was from diagonal center, and the other two points from the two ends with one meter distance to walls. When the area exceeded 30 square meters, samples were collected from five points, one was from the center, and the other four points from four angles with one meter distance to walls, and the altitude was 80-150 cm from vertical distance to the ground. The total number of microbes not more than 200cfu/m^3 was considered qualified.

消毒后和进行医疗活动之前，相对封闭的空间，面积≤30平方公尺时，在一条对角线上取3点采样，一般是中心和两端距墙壁1米处各取1点；面积＞30平方公尺时，应取中央及四角距墙壁1米处共5点采样，布放高度为垂直地面80cm~150cm，微生物总数≤200cfu/立方公尺为合格。

The latter two all reckon that basic shape of line element error band based on control points error is "dumbbell-shape",i.e.error in control end points is larger than points error between two control points.

后两者均认为以控制点点位误差描述的线元的误差带的基本形状呈"哑铃"形，即认为线元上端点的位置不确定性大于端点之间的点的位置不确定性。

Each group of access points comprises one or more access points with at least one group of access points having at least two access points.

每个接入点组包括一个或多个接入点，至少一个接入点组具有至少两个接入点。

The accurate selecting of homonymous points has two situations: when labels exist in the scene, the label's central coordinate is obtained as the homonymous points; and when there are no labels in the scene, all points are firstly displayed in perspective projection's way in the OpenGL environment, and then the homonymous points are selected by man-machine interaction.

同名点的选取分为两种情况：当场景中有标签时，本文提取了标签的中心作为同名点；当地理场景中不存在标签时，本文将两站点云以透视投影的方式在OpenGL环境中显示出来，然后通过人机交互选择的方法获得同名点。

The method relies on the facts that the row vectors composed of all the image points span, the same linear subspace as the row vectors composed of 3D space points span and that a basis of the subspace can consist of two row vectors composed of all the image points and one row vector in 3D space that is orthogonal to the former. The row vector can be determined, and the 3D reconstruction is accomplished. The novelty lies in the fact that the method can treat all the image points uniformly.

利用所有图像序列构成的行向量生成的子空间之和与三维空间点构成的行向量生成的子空间是同一线性子空间、同时由所有图像点构成的2个行向量外加一个行向量就可以组成该子空间的一个基底的特性，线性地求取子空间中的行向量，最后完成三维重建。

ABSTRACT: By using image processing software, based on the coordinates of clear points in images and the theoretical coordinates of the points in the reference coordinate system, the coordinate relation multinomial of pre-and post-correction control points can be established by means of the digital image correction technique and the coefficient in the multinomial can be sought on the basis of the coordinates of a certain number of control points.

前言 考古绘图一直是考古学研究中不可或缺的重要技术，能够反映考古遗迹的分布状况或者典型器物的多重特征。但是随着考古学研究的深入和对相关技术手段需求的增加，考古绘图技术却始终停留在通过直尺等量取数据、再使用直尺和铅笔绘图的水平上，成图精度很低，周期较长，图形品种单一，远远不能满足现代考古学研究的需要。

Survey, the fourth quarter of 2008 nearly 60% of the vote, director of the Institute believes that the operation of the Shanghai index point range for the 1500 ~ 2200 points, 23% of survey respondents believe that in the 2200 points ~ 2800 points, 18% of survey respondents believe that the following 1500 points.
