A model with nonuniform flow in the longitudinal direction is proposed for the relativistic heavy ion collisions and compared with the 14.6AGeV/c Si-Al and 10.8AGeV/c Au-Au collision data. The stronger influence of transparency on the distribution of heavier produced particles and the larger stopping in the heavier collision system are accounted for by using a new geometrical parametrization picture. The central dips in the proton and deutero...
