ResumoWe study the collective flow and multiplicities of small fragments and produced pions at different impact parameters in the 40Ca−40Ca collisions at Elab/A = 1.05 GeV. By comparing the results of a fully Lorentz covariant (RQMD) and non-covariant quantum molecular dynamics (QMD), we examine the dynamical relativistic effects. Near central collisions the difference between RQMD and QMD is not significant, while the difference between nuclear equations of state can be observed. With the increase of the impact parameter, the difference between RQMD and QMD becomes comparable with that between different nuclear equations of state.
