Abstract：
A mechanism of high-energy unequi-nuclei collisions is proposed in this paper.The spacetime evolution of high-energy unequi-nuclei collision is discussed with the help of the hydrodynamical model.It explained successfully the characteristic features of the rapidety distribution of the final state particles for the several typical cosmic ray events and the first preliminary results from an experiment of a beam of 200A GeV ¹⁶O collision on emulsion at the CERN SPS.
