查询词典 circle around

First, orthogonal circle operator was modeled in terms of Zernike orthogonal complex moment; the one-to-one mapping between the edge point and the parameters of the circle was established by the algorithm. Then, quadratic polynomial interpolation was adopted to further locate the edge points in the gradient direction.

首先根据Zernike正交复数矩建立圆物体边缘点与边缘参数之间的映射关系，并提取边缘点；然后利用二次多项式插值在梯度方向上对提取出的边缘点进行进一步定位；最后利用最小二乘法拟合插值后的边缘点，得到亚像素精度的圆参数。

Dated from Proterozoic to Mesozoic, they have poly-circle characteristics, found from one tectonic circle to another, which is very rare in the worldwide orogens. This reveals that the orogen and stable area of the world, the mantle and crust states of the Proterozoic and Phanerozoic are different in tectonic evolvement and dynamic process and that the rapakivi granite of the Qinling-Kunlun is a kind of orogenic granite different from the stable area of the Proterozoic.

它们出现在每一个大的造山旋回晚期，即向另一个构造旋回的转折期，这在世界造山带中是十分罕见的，反映出世界上造山带与稳定区元古宙和显生宙的地慢与地壳状态是不一样的，有着不同的构造演化历史和动力学过程，表明秦岭－昆仑地区的环斑花岗岩是一种有别于元古宙稳定区的造山型环斑花岗岩。

Pitch Circle is the reference circle from which all transverse spline tooth dimensions are constructed.

节圆：节圆是一个参考圆，花键的键齿的所有的横向尺寸都是以节圆为基础开始计算的。

As the number of impressions increase, however,the pitch circle diameter design becomes progressively more impracticable as the runner length, which is a function of the pitch circle diameter, is also increased.

可是随着型腔数目的增加，由于流道长度是等分圆直径的函数，所以设计的流道长度随着等分圆直径的增加变得不现实。

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。

With the method and the relation between the center of a circle and a triangle, the relation between the triangle and the circle can be determined rapidly, hence to quickly and correctly determine the position relation between the projections of the triangle plane and the tool in tool axis direction, and raise the efficiency of 3-axis NC machining.

借助于该方法及圆心相对三角形的位置关系，可以快速判别三角形与圆的位置关系，从而能据此快速、准确地判别三角片与刀具两者在刀轴方向投影的位置关系，提高3坐标数控加工干涉检查的效率。

This paper studied the case that there is a known point of tangency of a circle and a parabola while the center of the circle is on the recession of the parabola.

应用数形结合的方法，研究了已知圆与抛物线有一个切点，而圆心在切点处抛物线的凹向的情形。

We make a copy of the implementation of points and change those parts where a circle is different from a point. struct Circle gets an additional com- ponent

我们把坐标点的实现复制下来，然后改变那些圆不同于点的地方就可以了。struct Circle多了一个组成

Consequently, the circle viewed as a point still has Circle as a type description because the pointer in its .class com- ponent has not changed. draw is a selector function, i.e., it will take whatever argument is passed as self, proceed to the type description indicated by .class, and call the draw method stored there.

这个被看作是点的圆依旧是Circle类型的，因为其类型描述结构中的。class指针成员没有变化。draw是选择子函数，也就是说，它能接受任何以self参数传来的值，找到由。class指向的类型描述符，并且调用存储在那里的方法。

If the area of first circle is greater that the second one, print the area of first circle.

如果第一个圆的面积比第二个大，列印第一个圆的面积。

Alternatively, the con- trollers can use the synchronous rectifier itself or loss- less inductor current-sensing methods to provide overload protection with lower power dissipation.

另外，康威特罗勒斯可以使用同步整流器本身或亏损减少电感电流检测方法，以提供低功耗过载保护。

Mr. Dauber's other Schatz hangs in his home movie studio.

多伯把沙兹的另一件作品挂在家里的电影室。
