【摘要】 在一定条件下，处于横向磁场中的阴极斑点会出现停滞或反向运动。从力学角度出发，将单个阴极斑点看成一个达到动态平衡的质点，提出了单个阴极斑点运动模型，分析了阴极斑点发生正反向运动的原因，并试用该模型解释了一些实验所观测到的现象。更多还原

【Abstract】 Under certain circumstances, the cathode spot with transverse magnetic field applied may result in retrograde motion or immobility Considering the single cathode spot as a dynamic equilibrium material point, we describe a model, by which we explain the retrograde motion of cathode spot and analyze some experimental phenomena更多还原
