摘　　要：提出了用几何特征量来描述二次曲面和相关的边界曲线的方法 ,并据此研究了求交算法 ,避免了代数法中频繁的坐标变换 ,减少了浮点运算误差出现的几率 ,简化了曲面求交算法 ,使曲面求交算法更加稳定可靠。The method which is using geometry vector to describe quadratic s urface was expounded. On the base of this method, the way of inter section was studied, which avoid to do a lot of work on coordinate transform,also decrease error frequency of float operation.Using this way, the arithmetic of intersection was simptified and make it more stability.
