An iterative method is developed to calculate the coordinates of the intersection point of an incident ray with a B-spline surface in 3D space.

探讨了用阻尼最小二乘法对B样条曲面反射器进行优化设计的方法，通过优化运算修正控制顶点Z轴坐标，使得曲面在使用扩展光源时光形分布尽可能满足设计要求。

That work of such incomparable delicacy and form you are of course quite, quite incontestably right, as against the man who wrote the introduction.

我们感受身体的快感并不是坏事；所不好的是：几乎一切人都错用了、浪费了这种经验，把它放在生活疲倦的地方当作刺激，当作疏散，而不当作向着顶点的聚精会神。

Simply put , you tell on update how many vertic es indic es you want , and it reallocates the buffers only if necessary .

简单来说，你提交需要多少个顶点以及缓存数量，在可能的情况下，代码会自动重新分配缓存。

Let G = V(G,E be a simple graph with |V| vertices and |E| edges. Let |V|= p,|E|= q, if there exists f: V →{1,2,...,p} be an injective mapping, and define an inducedfunction f":E→{1,2,...,q} by setting f"=|f-f| for all∈E. If f maps E onto {1,2,...,q}, then f is said to be a Skolem-graceful labeling of G, the graph G is said to be a Skolem-graceful graph.

对一个给定的简单图G=V(G，E，|V|和|E|分别是图G的顶点数和边数，令|V|=p，|E|=q，如果存在一个一一映射f：V→{1，2，…，p}，使得对所有边∈E，由f′=|f-f|所导出的映射函数f′：E→{1，2，…，q}是一一对应关系，则称f是图G的一个Skolem优美标号，图G被称为Skolem优美图。

The overcutting on tool end is checked via comparing the tool radius with the circumradius or the radius of inscribed circle, and the touch interference of tool body based on the symbol of the vector distance from the triangle vertex to the tangent plane of tool body column.

在曲面加工的无干涉路径规划中，通过恰当选择刀具初始位置避免了接触点处的曲率干涉；通过比较刀具半径与曲面上三角片外接园半径的大小即可判断刀具底面干涉；而根据三角片顶点与刀杆切平面的有向距离的正负来判断刀杆碰撞干涉。

Mr Cayne's response to last week's crisis, which culminated in JPMorgan taking over Bear for $2 a share and wiping out a lot of his wealth, was a fitting end to a year during which Bear executives tried insouciantly to shrug off the doubts of investors and other banks about their business.

当摩根大通以每股2 美元的价格收购贝尔斯登、并消解掉凯恩的不少财富时，最近的这场危机达到了顶点。在这一年里，贝尔斯登的高管们一直漫不经心地试图打消投资者以及其他银行对其业务的疑虑，而凯恩的反应则为这一年划上了合适的句点。

Analyze the distributing rule of velocity and velocity instantaneous, and also study the relationship between comers and the relationship between corners and position when the mechanism turning.

研究了该机构的卡当运动，分析了运动过程中的速度和速度瞬心的分布规律，并分析了卡当运动过程中各转角间及转角与顶点位置间的相互关系。

Firstly the constraints of weak vertex cover set are analyzed and the integer programming formulation for it is given.

首先分析了弱顶点覆盖集的约束关系，并给出了问题的整数规划形式。

The triangular face internal pixel color under the vertex color diffuse reflectance, it is a triangular gradient colors surface.

该三角形面内部的像素颜色根据顶点颜色进行漫反射，因此是一个颜色渐变的三角形面。

Furthermore, all arrays used to hold the line and polygon coordinates are allocated dynamically so the only limit on the number of polygon vertices and intersecting lines is the amount of available memory.

此外，所有数组用于保存线和多边形的坐标是动态分配的，因此对多边形的顶点数目只会限制和交叉线，是可用内存量。

It has been put forward that there exists single Ball point and double Ball points on the symmetrical connecting-rod curves of equilateral mechanisms.

从鲍尔点的形成原理出发，分析对称连杆曲线上鲍尔点的产生条件，提出等边机构的对称连杆曲线上有单鲍尔点和双鲍尔点。
