报告简介： The nuclear equation of state, particularly the isovector sector usually termed as symmetry energy is a key input to understand the evolution properties of dense stellar object and the merging of two neutron stars. On the other hand, the nuclear symmetry energy varying with density has also effects on the dynamics of heavy ion collisions. In return HIC provides a useful terrestrial tool to constrain the nuclear symmetry energy. In this talk I will briefly review the status of the study on symmetry energy, and mainly present our recent studies on isospin dynamics in HIC which allows us to constrain stringently the nuclear symmetry energy be low saturation density. Besides, the future plan with two spectrometers under construction, CEE and CSHINE, and the related programs are introduced.
