用对偶矢量计算开环机构末杆自由度的应用及算例

Application of Dual Vector to Calculation of Pole End in Open Loop Mechanism

论述了用对偶矢量计算开环机构末杆自由度在机构自由度计算中的应用，并给出以这种方法计算各种不同类型闭环机构自由度的算例．

This treatise attempts to explain the application of dual vector calculating the pole at the end in open loop mechanism to the calculation of poles in mechanism, and examples are given to illustrate the caluclation of the close loop mechanism of various types.
