Abstract: 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.
