利用通常的瞬子方法，我们得到了三阱势垒中量子隧穿引起的能量分裂。结果表明，传播子中与能量分裂中点有关的项与双势阱情况下的能量分裂中点有关，它与左、中威尔斯频率的代数平均成正比。能量分裂的结果与已知的变分计算结果一致。
By using the usual instanton method, we obtain the energy splitting due to quantum tunneling through the triple-well barrier. It is shown that the term related to the midpoint of the energy splitting in propagator is quite different from that of double-well case, in that it is proportional to the algebraic average of the frequencies of the left and central wells. The result of the energy splitting is consistent with the known variational calculation.
