摘要：
By means of the thermofield dynamical theory, the effective mass of omega meson is calculated by summing the bubble diagrams. It is found that the formula for the effective mass of the rho meson can also be used to describe the omega meson in the low density region, but the parameter n and the critical temperature T-c depend on the density. The temperature and density dependence of one omega exchange potential of nucleon-nucleon interaction are given. The conjecture of Brown and Rho about the effective masses of mesons is discussed.
