The quantum tunneling in one - dimensional time - dependent periodic potential is investigated

theoretically. Two models of the one - dimensional periodic potentials are established and discussed in different

conditions，in which the quantum tunneling problem in one-dimensional time-dependent periodic potential can be

treated as one model.

Key words： quantum physics; quantum tunneling; one - dimensional time - dependent periodic potential; transmission coefficient; reflection coefficient; wave function
