摘要：We review recent progress in lattice QCD at finite density. The phase diagram of QCD and
the equation of state at finite temperature and density are discussed. In particular, we focus on
the critical point terminating a first order phase transition line in the high density region. The
critical point is one of the most interesting features that may be discovered in heavy-ion collision
experiments. We summarize the current discussion on the existence of a critical point in the QCD
phase diagram and discuss some attempts to find the critical point by numerical simulations.
