主　　题：point critical entropy 

摘      要：Isospin effects of the critical phenomena were studied via Xe isotopes in the frame of the lattice gas *** the critical temperatures for four Xe isotopes are close to 5.5 MeV at the same freeze-out density of about 0.39ρ*** critical values of power law parameter of mass distribution,mean multiplicity of intermediate mass fragments,information entropy and Campi s second moment show minor dependence on the isospin at the critical point.
