| 摘 要： | 正轴方位投影、伪方位投影、圆锥投影、伪圆锥投影、圆柱投影、伪圆柱投影和多圆锥投影,实为不同类型的经纬线族的组合。在对经纬线类型定义的基础上,根据不同投影的经纬网构成规律,分别对方位投影等7种投影给出了新的数学定义。新的地图投影定义,以其简明的数学形式,定量地揭示了不同投影的经纬网特点和本质特征。 |

| Abstract: | The azimuthal projection, pseud-azimuthal projection, conic projection, pseudo-conic projection, cylindrical projection, pseudo-cylindrical projection and polyconic projection are combination of families of meridian-and parallels, On the basis of definition of meridians and parallels and according to the rule of construction of different meridian and parallel nets of projections, authors have made new mathematical definition for seven projections which has quantitatively shown the characteristics of different map projection nets. |
