| 摘 要： | 文章讨论了在宏观、低速条件下,带电粒子在正交恒定电磁场中的3种运动轨迹问题。当带电粒子沿垂直于电磁场方向或者沿电场方向进入电磁场时,粒子作圆心随时间变化的类似旋轮线运动;当带电粒子沿磁场方向进入电磁场时,粒子的运动轨迹是一条空间立体曲线。并用MATLAB软件模拟了以上三种轨迹曲线。

| Abstract: | This paper discusses the orbit of a charged particle in the electromagnetic field under the macro view,low speed conditions.We discussed three orbits of a charged particle in special conditions.If the charged particle enters the electromagnetic field in the direction which is perpendicular to electromagnetic field direction or parallel with electric field direction,its orbit will be a orbicular curve and its centre vary with time.If the charged particle enters the electromagnetic field in the direction which parallel with magnetic field direction,its orbit will be a complicated three-dimensional curve.We also simulated the three kinds of orbits by use of MATLAB software. |
