摘要
本文用拓朴变换法解决了用辅助截平面法、球面法、柱面法等不能解决的曲面相交问题，它拓广了曲面相交问题的解题思路．
Some curved surface intersection problems which cann't be solved with traditional methods such as auxitiary plane.right cylinder and sphere surface are solved by means of topological transfer- this would bring new thouthg in solving curved surface intersection problems.
