In existing technology, the nonnal way is adopting the four-bar linkage mechanism to imitate the arc or the linear movement. On the theoretical analysis, its movement precision can meet the requirement, while in the operation, because of the abrasion of bearings in gemel, which do much greater effect on movement than the former, its movement precision goes much beyond the theoretical value.

现有技术中一般是采用四连杆机构来仿弧线或直线运动，从理论上讲其运动精度是能够满足要求的，但在实际使用中，由于铰链点轴承的磨损（另外，装配时也预留了一定的轴承间隙），对运动轨迹产生的影响很大，其运动精度就大大超出理论值。

Compared with numerical method, analytic approach not only has clear geometric meaning, but improves the solving efficiency considerably.
