Abstract：
In the paper we discuss the role of the axial U(1)_A symmetry in the chiral phase transition using the U(N_f)_R×U(N_f)_L linear sigma model with two massless quark flavors. It is expected that above a certain temperature the axial U(1)_A symmetry will be restored. A string-like static solution, the η string can be formed and detected in the ultrarelativistic heavy-ion collision process.
