平面、柱面折射的原理及其应用

The Principle and Application of Plane and Cylinder Refraction

在采用投射法建立两空间的拓扑对应时，以中心投射、平行投射、辐向投射较多，而借助于平面、柱面折射进行拓扑变换的作图极少。本文对这种变换的作图原理、应用条件及作图方法进行论证和完善，并用实例证明其可行性．

When making topological maps with projection between two spaces,the center projection,parallel projection and radius projection are more used,while the drawing of topological transformation by the plane and cylinder is less used.In this paper the drawing principle,method and applied condition of the transformation are proved and perfected,the feasiblity is proved with the examples.
