查询词典 point circle

Carried out generalized Mises yield criterion , yield curve on the n flat face was circle curve, and different elected parameters correspond to external angular point circumcircle、 internal angular point circumcircle and incircle of Mohr-Coulomb unequiangular hexagon. According to unequiangular hexagon, circle yield curve which had the same area as hexagon can be found, and corresponding yield criterionwas equilateral circle yield curve.

3广义米赛斯准则在π平面上的屈服曲线为圆曲线，选择的参数不同对应有莫尔—库仑不等角六边形的外角点外接圆，内角点外接圆和内切圆，对于不等角六边形，还可以找到一个面积和六边形相等的圆屈服曲线，对应的屈服准则为等面圆屈服曲线。

According to the principle of the diameter of a circle corresponding to the right angle and the principle of short side for little angle in right triangle, projecting the initially-chosen point to the hyper-planes of the linear equation group in which every linear equation can be regarded as a hyper-plane and the projection points can be obtained. The initially-chosen point, and one arbitrary projection point, and the solution point are all on the surface of the relative hyper-geometry ball, therein-to, there is a projection point which is nearest to the solution point and it can be regarded as the next iterative initially-chosen point, so the solution problem of the linear equation group can be changed as an iterative problem of approaching the solution on the surface of a hyper-geometry ball.

根据直径对应的圆周角足直角以及直角三角形中短边对小角的原理进一步知道，当将初始点向线性方程组中各个方程所代表的超平面上投影得到投影点时，初始点和其任何一个投影点及方程组的解点都将位于一个相应的超球面上，其中必定存在一个投影点离问题解点的距离最短，即把该点作为下一次迭代的初始点，从而可将线性方程组求解的问题变成球面上逼近解点的迭代问题。

The method for the point sets selection of point Hough transform and the scan direction for image of searching the point sets were improved by using the geometrical characteristic of the concentric circles:The center of the concentric circles was obtained in the accumulative array firstly,radius was obtained by the mean of distance between the circle center and every edge points afterwards,both the circle center and the edge of the concentric circles were detected accordingly.

利用同心圆的几何特点对点Hough变换边缘点的点组选取方法和搜索点组的图像扫描方向进行了改进：首先由累加阵列确定同心圆的圆心，然后由圆心到各个有效边缘点距离的均值求出半径，从而检测出同心圆的圆心与边缘。

The basic principle is based on spherical astronomy and elementary geometry of the trajectory mapping method based on the observation of a celestial body zenith distance, then the ship is located in order to sing the next point as the center of this satellite zenith distance of the ship's position as the radius of the circle, observing the same two objects, or objects at different times of the two observations, we can get two ship's position round, then the ship must have been a point of intersection of two ship's position on the circle.

其基本原理是建立在球面天文学和初等几何中的轨迹作图法基础上的，观测一个天体的天顶距，则航船就位于以星下点为圆心，此星天顶距为半径的船位圆上，观测两个天体或者不同时间同一天体的两个观测值，就可以得到两个船位圆，则航船一定在两个船位圆的一个交点上。

Since representation of the subclass object starts out like the representation of a superclass object, the circle can always pretend to be a point — at the initial address of the circle's representation there really is a point's representation.

因为子类的表示开始于一个非常像其父类的结构，所以圆可以把自己伪装成一个点——圆的物理表示的地址的前面部分就是一个点的表示。

The EM field of arbitrary point in an irregular loop can be considered as the sum of the EM field of many circle loops in the irregular loop at the point. Therefore the authors may obtain the EM field of the irregular loop as long as the authors work out the EM field of each of the circle loops.

不规则回线内任一点的电磁场可以看成是其内部多个圆形回线在该点的电磁场之和，因此，只要求出不规则回线内各个圆形回线在该点的电磁场，将它们叠加就可得出不规则回线在该点的电磁场。

Planar point set the minimum inclusive circle, that circle with a minimum point of the plane are all incorporated.

详细说明：平面点集的最小包容圆，即用一个最小的圆把平面内所有的点都包容在内。

Turkish embroidery embroidered disc is unique to acupuncture, which uses two needles in the embroidered cloth on the plate under the binding on, arranged into a point, circle, color beautiful, luxurious.

盘绣是土族刺绣的特有针法，即用两根针在所绣的布块上上盘下扎，布置成点、圈，配色鲜丽、华贵。

Then thetheorem can be proved by calculating the distances of centres between a nine-point circle and...

然后通过计算九点圆与内切圆、九点圆与旁切圆的圆心距，使定理获得证明。

Try to see the square perfectly; when you can do so draw a circle within the square; now place a point in the center of the circle; now draw the point toward you about 10 inches; now you have a cone on a square base; you will remember that your work was all in black; change it to white, to red, to yellow.

试著看清楚这个正方形；看清以后，在正方形中画一个圆；在圆心画一个点，然后把圆心的点向你自己的方向拉近10英吋。现在，你在一个正方形的底面上做成了一个圆锥；你应该能记住这个圆锥是黑色的；再把它变成红色、白色、黄色。

The split between the two groups can hardly be papered over.

这两个团体间的分歧难以掩饰。

This approach not only encourages a greater number of responses, but minimizes the likelihood of stale groupthink.

这种做法不仅鼓励了更多的反应，而且减少跟风的可能性。
