In this paper, we have studied two coupled relativistic superfluids with spontaneous U(1) symmetry breaking, using Poisson bracket technique. After constructing the commutators between thermo-quantities and field quantities, the equations of motion are obtained. These equations describe the system in the frame of two-constituent superfluid theory and provide a clear picture relating the symmetry breaking and the physical quantities explicitly. The interference effect is discussed and the Josephson-type equation is also given. Furthermore, the dissipation effect and entropy production mechanism are presented and the dissipative coefficients are given explicitly in the first-order theory framework.
