摘　　要：By solving two body Dirac equations with potentials at finite temperature,we calculate the dissociation temperature T_(d) of B_(c) mesons in quark-gluon plasma.It is found that T_(d) becomes higher with the relativistic correction than the T_(d) from the Schrodinger equation.Both the short range interaction and the constant term of the potential at the long-range scale have a contribution to the shift of T_(d),while the spin interaction is negligible.
