摘要
The transport process of charge density wave (CDW) in a quasi-one dementional conductor can be explained by the Zener tunneling of coherent exciton gas. It is inferred from the model that CDW state is more orderly than normal electron state. The phase transition changing into normal electron state from CDW state is of second order without impurities and of first one with impurities.
