中文摘要：
为了揭示正方位投影、伪方位投影、正圆锥投影、伪圆锥投影、正圆柱投影、伪圆柱投影和多圆锥投影等常规地图投影的构图规律,采用比较分析的方法,发现这7类投影的图形具有镜射变换关系。不同类型的投影满足不同的变换条件。根据镜射变换满足的不同条件,可对上述7种地图投影进行定义,从而建立基于镜射变换的常规地图投影定义体系。
英文摘要：
In order to reveal the composition regularity of regular map projection such as azimuth projection,pseudo azimuth projection, positive conic projection, pseudo-conic projection, normal cylindrical projection,pseudo-cylindrical projection and multi-conic projection,the paper uses a method of comparative analysis and concludes that these seven types of projections have the relationship of reflex transformation.The transformation conditions that different projections satisfy are different.According to the different conditions that reflex transformation can meet,this paper defines the above seven map projections,thus establishing a new definition system of general map projections based on reflex transformation.
