Abstract：
In the framework of the relativistic mean field theory nuclear matter including Δ isobars is investigated.The numerical results indicate that no matter what parameter set is chosen,there exist abnormal states.The high temperature is critical factor for abnormal states.The critical temperature that abnormal state begins to appear is T_c=127MeV.When T≥165MeV the normal state will disappear and only abnormal state survives.The influence of abnormal state on the EoS of nuclear matter is also discussed.
