Abstract:

Based on the mean value of a mechanical quantity being a measurable value in experiment and the  definition   of coherent state, we discussed the charge mean value of  the LC circuit and the time evolution formula of the current intensity, the wave function of coherent state and the quasi\|classical wave function satisfying the Schrdinger equation. The results show the quasi-classical solution of mesoscopic circuit of charge quantization.

Key words: mesoscopic circuit, coherent state, quasi-classical description
