Abstract：
The variation of equipotential lines of interaction potential with the intuitively gives the information about the fluctuation of the potential in intermediate energy heavy ion collisions.At the early stage of collisions the potential value in the central region of the system could be positive.The followed irregular deformation of equipotential lines in the region,especially the appearance of the negative curvatUre of the equipotential lines causes the chaotic nucleonic motion.The phase difference of the neighbouring nucleons increases with time exponentially,and the phase space of nucleons thus separates and caussd the multifragmentation.
