| Abstract: | Based on the theory of homthetic transformation, the concept of homothetic curvedsurface is proposed, from which deduced two special features of the surface. In the lightof these features, a method to solve the problem. concerning the intersection line ofconicoid intersection is developed. Both the charting principle and application of such amethod are also studied. |
