查询词典 intersection theorems

Common uses for sets are fast membership testing, removing duplicates from a sequence, and computing mathematical operations such as intersection, union, difference, and symmetric difference.

集合的常用场合是快速测试某元素是否在集合中，或者是从一个有序类型中删除重复元素，或者是做一些数学运算，比如求集合的交集、并集、差和对称差。

The output of the control is commonly referred to as a cross tabulation because it shows summary values for an intersection of categories.

透视表组件的输出通常被称为"交叉表"，因为它显示了各类别交叉点的总和。

He'll get in, and Talbot will give you directions as you hit each intersection.

他将得到怎样，和陶会给你指示您按下每个路口。

In each step the tangent plane of limit state surface at the previous iterative point is calculated firstly, and then a line from origin to a point on the plane is determined whose intersection with limit state surface satisfies the requirement of feasible direction and convergence.

算法在每步迭代中先计算极限状态曲面在前步迭代点处的切平面，然后在此切平面上选定一个点，使该点和原点的连线与极限状态曲面的交点满足可行方向和收敛的要求。

Given the two points, one can construct the points of intersection of the line and the circle.

给定了两点就可以画出这直线和圆的交点。

Through the hypersingular integral equations of 3-d crack perpendicular to the interface given in the preceding, the principles of finite-part integrals and of limit are further made use of to pick the hypersingular integral equations of 3-d crack terminating at the interface On the basis of the equations, starting strictly from 3-d theory of elasticity, stress singularities of intersection-line near the front edge of the 3-d crack terminating at the interface are analyzed by virtue of dominant-part analysis of 2-d hypersingular integrals.

根据前面所得到的与界面垂直的单片裂纹超奇异积分方程，进一步运用有限部积分原理和极限理论，推导出了与界面垂直相抵的三维平片裂纹的超奇异积分方程。在此基础上，严格从三维理论出发，使用二维超奇异积分的主部分析方法，对与界面垂直相抵的三维平片裂纹前沿交线上的应力奇性指数进行了分析。

Aimming at the shortcoming in precision measurement of artillery adjusting, a kind of three-ply intersection measurement method based binocular stereo vision is proposed. CCD is used to capture images of the sign object attached on gun barrel, and three-dimensional coordinates is calculated by geometrical projection relation of the sign object image.

针对火炮调炮精度检测中存在的不足，提出了一种基于双目立体视觉的三重交会测量方法，在炮身管上附加球状标志物，利用CCD摄像机获取标志物图像，通过标志物成像的几何投影关系计算球心的三维坐标。

Only in the thoughts of each site, always look back on past events, I look at the cooling laugh. allow themselves to watch in your every intersection, you want to put an injury, a bite of injuries, and I still have no reason to regret in anticipation, readily look at the memory when he could not find the road to see their hopelessness of the decline in the extreme you would like to Lane.

穿乱，留我独自彷徨，不知道起点，终点，只是在每个思念的站点，总是对往事回首，看我的冷却一笑，让自己守望在有你的每一个路口，把想你想做一种伤，一种噬人的伤，而我依旧在无悔的期盼，随手翻看的记忆里找不到来时的路，看自己无望的沉沦在想你的极端里。

No tracing is required at all in this torus/sphere intersection algorithm .

提出了一种不需跟踪的求交算法。
