为进行斜齿锥齿轮副的齿面接触分析，并直观显示齿面接触区，利用圆向量函数和球向量函数的矢量回转和坐标变换方法，建立了斜齿锥齿轮齿面接触分析的数学模型；
To analyze and display the contact of skew bevel involute gears, a mathematic model was established by vector gyration and coordinate transform of circle vector functions and sphere vector functions.
读写改造过的梯度矢量和其分量和梯度一样的方式，你可以通过加rg的下标在你的宏中来得到梯度向量和其分量。
In the same way as the gradient, you can add the RG su_x to your macro to access the reconstruction gradient (RG) vector and components of a variable quantity.
将每个像素的三个色彩通道看成是一个三维矢量，则矢量的单位方向向量和亮度分别表示像素的色彩和亮度。
The three color channels of each pixel were regard as 3-dimensional vector, and the unit directional vector and its magnitude represented the chromaticity and the pixel brightness separately.
