摘　　要：提出了一个用来检测多个平面运动链之间的同构对象的新的恒量序列，该恒量序列把杆的级别和运动副的类型、自由度都考虑在内，被称为改进了的各杆总距离等级序列。并提出了一个用以得到这个恒量序列的算法。同时。A new method of invariant sequence has been proposed for detecting isomorphism among planar kinematic chanis with simple joints.This method takes into account the degrees of links,degrees of freedom and types of joints in the kinematic chain.This new method may be called the arranged sequence of modified total distance ranks of all the links(ASTDRL). An algorithm has been developed to obtain the above mentioned process.A computer aided method has also been presented for identifying distinct mechanisms of a planar kinematic chain with simple joints.
