摘　　要：研究不作速度分析 ,仅用三心定理无法求解的速度瞬心问题。用射影几何理论阐明有关定式求解的正确性及方法 ,讨论定式的有效性及组合应用的可能性 ;This paper studies the method of finding the instant center.The problem of finding the instant center can not be solved only by the Aronhold kennedy theorem without velocity analysis.The correctness of relative configurations and the method for finding instant centers are expounded by projective geometry. The validity of the configurations and the feasibility to combine them for application are reviewed. The procedures for finding and distinguishing valid configurations based on adjacency matrix for a computer are presented.
