摘　　要：本文系统地讨论了球心投影的线性变换——改良球心投影的性质和应用，揭示出它保持两点角度不变形的特性，具有理论和应用价值，开拓了球心投影新的应用前景。: In this paper the characteristics and application of the linear transformation of gno-monic projection, a kind of modified gnomonic projection are systematically discussed. The mature of preserving true angle between points are revealed. It has theoretical and applied value and shows a new practical prospect of gnomonic projection.
