摘　　要：研究了离子在Penning阱内的运动规律。根据在实验中所采用的Penning离子阱结构及电磁场分布特点，列出并求解了阱内离子运动方程，对其中各种运动及稳定性进行了分析，得到如下结论：阱中离子的运动为简谐振动、回旋运动和漂移运动的叠加，且这3种运动是稳定的。The ion＇ s movement law in Penning ion trap has been studied in this paper. Based on the structure of Penning ion trap adopted in experiment and the distributing character of electromagnetic field, this paper educes ion movement equation and resolves the equation, analyzes in detail ion three kinds of motions and stability, finally summarizes the study on ion motion： Ion movement in Penning ion trap is summation of axial oscillation, circular cyclotron motion and circular magnetron drift motion. , these movements are stable.

关 键 词：离子阱 简谐振动 回旋运动 漂移运动
