摘要：

We study the quantum effect of a mesoscopic dissipative-coupled RLC circuit of the capacitances. We find that if the quantum dissipative system is in the vacuum state at the initial time, it will evolve to a squeezed coherent state under the effect of an external pulse source because of the presence of the coupling and damping.
