After phenomenologically considering the RF heating the RF heating as an additive contestant to the buffer gas damping, we calculated the storage time of trapped ions in terms of the mean first passage time of the Brownian motion of their energy in the pseudopotential well of a Paul trap.
结合缓冲气体Ｈｅ对囚禁离子云Ｎ＋２的冷却实验结果，给出了在综合考虑射频加热和缓冲气体冷却效应情形下，阱中囚禁离子数随时间变化的理论模型，讨论了Ｐａｕｌ阱中的加热系数。
