摘　　要：通过求解带电粒子在均匀电场中与坐标系选取无关的三维矢量相对论运动方程,进而利用洛伦兹变换方法,求得了带电粒子在E2>H2的均匀正交电磁场中相对论运动轨迹的一般三维矢量式.并使用Mathematica软件在直角坐标系中描绘了相应的粒子相对论运动轨迹图.The motion of a charged relativistic particle in the （E2 〉H2） uniform orthogonal electromagnetic field is studied by solving the equation of motion in a special frame in which the field becomes purely electric, and then transforming the solution under a Lorentz boost. The three-dimensional vector expression of the particle＇ s relativistic motion is obtained and the corresponding trajectories in Cartesian coordinate are graphed by using software Mathematlea
