建立轴射圆柱面投影方法,研究轴射圆柱面投影下球面向圆柱面投影的理论,解决正投影无法解决的复杂的旋转体投影问题.用轴射圆柱面投影法的投影理论,建立球面和圆柱面的一一对应关系,找出二者之间的某些几何规律,该投影下任意形状的球面投影到圆柱面上是相等的,建立球面的轴射圆柱面投影定理,解决球面不规则计算问题.
The author of this article establishes the projection system of axis radiate to cylindrical surface（ that is the phenomenon of all axis perpendicular light lines to the projection of cylindrical surface）, researches into the theory of projection of spherical surface toward cylindrical surface under the axis of projection of cylindrical surface, and solves the complicated problem of body of rotation projection which can＇ t be solved by orthography. The author using projection theories of the methods of axis of projection of cylindrical surface establishes the correspondence relations of shpherical surface and cylindrical surface, and finds out some geometric laws between them-under this projection the distance are equal from any form of spherical surface projections to cylindrical surface, The author establishes the theorem of axis of projection of cylindrical surface of spherical surface and solves the problems of irregular calculation of spherical surface.
