空间中关于直线的对称问题

The Question on the Line of Symmetry in Space

本文讨论了三维空间中，点、曲面、曲线关于直线的对称问题，从而给出了求点、曲面、曲线关于直线对称的对称点、对称曲面、对称曲线方程的方法。

In this article we have discussed the point, curved surface,curve and the question concerning the line of symmetry in the three-dimensional space. Thus we have got the way that we can work out about the point, curved surface, curve, the symmetric point of the line of symmetry curved surface of symmetry and symmetical curved eguation.
