摘要
研究了三维空间内点、曲面、曲线关于直线的对称性问题,从而给出了求点、曲面、曲线分别关于直线的对称点的坐标、对称曲面和对称曲线方程的方法。
The point, curved surface and curve regarding the symmetrical problem of straight line in three-dimensional space is studied and then given the methods to curved surface and curve regarding the symmetry of straight face and symmetrical curve find out the coordinate of symmetrical point of point, line, and also the equation of symmetrical curved surface and symmetrical curve.
