The calculation results show that the populations between the two states are Rabi oscillation in the absence of the rf field, square-wave oscillations in the presence of the slow rf field, and stair steps oscillations in the presence of the intermediate rf field.

计算结果表明：当调频场的频率比较低时，从一个态到另一个态的跃迁几率随时间演化为方波振荡；当调频场为中频时，跃迁几率为阶梯型振荡；在高频调频场中出现调频场的多光子共振。
