摘      要：The directed and elliptic flow in collisions of ^(112)Sn+^(112)Sn at energies from 35 to 90 MeV/nucleon are studied in an isospin-dependent quantum molecule dynamics *** increasing incident energy,the directed flow rises from negative to *** magnitude depends on the nuclear equation of state(EOS).However,the elliptic flow decreases with increasing incident energy and its magnitude is not very sensible to *** studies of the impact parameter dependence and the cluster mass dependence are also *** study of directed flow at intermediate energies thus provides a means of extracting the information on the nuclear equation of state.
