three plane projections 三面投影图
A sphere cannot be represented on a flat plane without distortion, which means all map projections distort in one way or another.
球体在平面上不进行扭曲就无法表现出来，这意味着所有制图方式都会以某种方式出现扭曲。
The theorem of Projections of accelerations of plane motion of rigid body is derived in this paper. Some applications of this theorem are given as examples.
