摘　　要：通过精确求解含时的量子体系 ,研究了在周期耦合驱动下电子在两量子阱中的受迫振荡 .电子在双量子阱间的隧穿可由周期性外场控制 .得到了电子被囚禁在单一量子阱中的条件 .The behaviour of an electron between two quantum wells, is studied by exact solution of a time-dependent Schrodinger equation. The time-dependent electron occupation-probability is obtained analytically as a function of the energy difference between the two wells, coupling constant and driving frequency. The condition that electron can be trapped in a single quantum well is obtained.
