本文系统介绍矢量图的映象图法。这种方法能消除用传统的蒙日投影法画空间矢量图时出现的图面不清晰等缺点。文中着重说明映象图与投影图对应关系的基本原理,介绍了配极对应在解决垂直问题时的应用。在说明映象图的实际应用中结合了农业机械常用的空间机构的运动学问题,以供从事实际工作的同志参考。 This article systematically introduces vector map method. This method can eliminate the shortcoming of the unclear picture when drawing the space vector image with the traditional Mengri projection method. This paper focuses on the basic principle of the corresponding relationship between the map and the projection map, and introduces the application of the counterpoise to solve the vertical problem. In describing the practical application of the map, the kinematics of the space agencies commonly used in agricultural machinery are incorporated into it for reference by comrades engaged in practical work.
