摘要：

We have studied the behaviour of the mean misfit and the specific heat of the one-dimensional quantum sine-Gordon system (g2 = 4pi) with a misfit parameter for two models of impurities. We have used a Fermi-Bose relation and a self-consistent t-matrix approximation for impurities. We have made numerical and analytical calculations for the mean misfit and the specific heat for various cases.
