Seeking the Intersection Points of a Straight Line and a Rotating Curved Surface with Topologic Transformation

运用拓扑变换求解回转曲面与直线的贯穿点 .这种方法把求解曲面与直线的交点问题转化成为利用积聚性投影特征解题 ,从而使解题过程易于理解 ,便于操作 .实践结果表明 。

Topologic transformation is applied in this paper to the seeking of the intersection points of a straight line and a rotating curved surface. This method transforms the problem of seeking intersecton points of a straight line with a rotating curved surface into a solution based on gathering projection characteristics, and makes this solution easy to understand and convenient to operate. The result from the practice shows that much time and labor can be saved in solving the problem.
