Abstract: According to the physical mechanism of teh generation of the resistance or the collisions of electrons with the phonons, the capacitive couple4d electric circuit is quantized when there exists resistance in the coupling part. Effects of the resistance in the coupling part on the quantum fluctuations are given. At the same time, the thermo effect is considered. Results show that the coupling capacitance can reduce the quantum fluctuations of the electric charge in the component circuits and the coupling part.

Key words: capacitive coupled electric circuit, damping, quantum fluctuations
