摘要
通过整合"有界磁场"带电粒子运动轨迹中的弦角关系以及溯源它的动量变化,找出"3个关系"来处理粒子运动的相关问题,可以省去轨迹圆绘图的烦扰.
By integrating the chord angle relationship in the motion trajectory of a charged particle in the"bounded magnetic field"and tracing its momentum change,we could find"three relationships"to deal with particle motion related issues,which would save the trouble of drawing the trajectory circle.
