摘要
在证明螺旋的相关性与坐标选样无关的基础上．按不同几何特点讨论了螺旋的相关性．并提出最大线件无关组构成机构的原理．
It is based on that the relativity of the screw system is independent upon the selection of coordinate system discuss on the dependency of screw system on different geometrical conditions. and propose the principie of the maximum limear independent group to construct mechanisms.
