法曲率 meaning in English
[数学] normal curvature
Examples
- Suanifolds with the vanishing normal curvature tensor in locally syetric space
局部对称黎曼流形中法曲率张量场消失的子流形 - Changes of the induced normal curvature and the relative sliding coefficient of gears are the important factors
齿面诱导法曲率和滑动系数的改变是重要的影响因素。 - Because the data mutate on the position that is the edge , the normal curvature on some orientation changes from positive to negative . so it is thought whether some point is judged the edge - point by this character
由于边缘是图像上像素发生突变的位置，所以在图像曲面上某一方向的法曲率值会出现由正到负的变化，故此应用这个性质来判断曲面上某点是否为边缘点。 - By pre - dividing parametric region of the surface and introducing the concept “ maximum absolute normal curvature ” at a point on the surface , the method adopts “ divide and conquer ” approach triangulating the parametric region of the surface piecewise
该算法通过对曲面的参数域进行预剖分，以及引入曲面上一点处的“最大绝对法曲率”的概念，采用“分而治之”的方法分片对参数曲面的参数域进行三角形网格剖分。 - According to the differential geometry theory , the principle curvatures and principle relative curvature of the spur gear and the fg in line contact and point contact , the tooth surface relative speed and the tooth contact interface are analyzed , whose distributing on the tooth surface are visualized by computer
在齿面的几何特性研究中，利用微分几何的原理分析了圆柱齿轮和面齿轮的齿面曲率、线接触和点接触面齿轮传动的主诱导法曲率以及啮合过程中齿面的相对速度和接触区域计算问题，并获得有益的结论。
