查询词典 unit circle

From Poisson matrix, we can observe volume-preserving vector fields. By using Geiges-Gonzalo's existence of contact circle Theorem [3] , we show the existence of volume-preserving circle on3-manifolds which says that every3-manifold admits two linear independent vector fields preserving a same volume form.

通过Poisson矩阵可以观察出保积向量场，再利用Geiges-Gonzalo的接触圆存在性定理[3]，我们证明了保积圆的存在性：每个闭的3-流形上都存在两个处处线性无关的保积向量场并且它们的常系数线性组合仍是保积向量场。

The internal structure of the Earth's poorly understood, or even Uu understanding, especially of the circle of the Earth's structure and the layer between the circle tilt differential problem is not the concept.

对地球的内部构造了解甚少，甚至屗了解，尤其对地球是层圈构造和层圈之间存在倾斜差速问题根本没有概念。

It is obviously that a planar point set has innumerable circumscribled circles. To get a minimum circumscribled circle, a mathematical model is built to transform the problem of getting a minimum circumscribled circle to the problem of optimizing function and to solve the function optimization with genetic algorithm.

为求得最小的包容圆，建立了求平面点列包容圆的数学模型，将求最小包容圆问题转化为函数优化问题，并用遗传算法解决了这个函数最优解的求解问题。

In the new algorithm,the circle detection problem is decomposed into two stages consisting of a 2D Hough transform to find circle centre and a 1D Hough transform to determine the radius.

利用局部梯度信息将检测圆所需的3D Hough变换转化为一个2D Hough变换检测圆心位置和一个1D Hough变换检测圆的半径。

Since cross ratio is an invariant of the group of all Mbius transformations,and a Mbius transformation maps a circle into another circle, it is convenient to represent a segment of circular arc with a parametric complex rational function.

利用Mbius变换的保交比性质和保圆性质，给出了一种快速、简便地生成平面上的一段精确圆弧曲线的新方法。

All this to say that I'm glad filmmaking hasn't become completely ironic. I can enjoy an ironic film as much as the next person, but they usually involve a message of some sort. One that's delivered in a smirkingly clever way that requires little in the way of talent.

所有这些都是说，我很高兴电影制作没有变成完全讽刺艺术，我可以和下一个人一样享受讽刺电影的乐趣，虽然他们经常会被划归到一定级别，技术方面不需要很高的才能。
