摘要
对运动方程法求解像管中的电子轨迹进行了研究,先利用64点拉格朗日插值公式和球面阴极外插求出空间任一点的电位,然后用变步长龙格-库塔法求出电子运动的轨迹.通过计算同心球系统的典型轨迹,与理论值比较,其精度达到10-3.
Abstract
Kinetic equation was used to solve electron trajectoy. By utilizing 64-point-Lagrange-interpolation and spherical cathode extrapolation, potential of random point in space was solved. Then by using changing-step Runge-Kutta method, electron trajectory was solved. Typical electron trajectory of the concentric spherical system was computed. Compared with the ideal datum, its accuracy reaches 10-3.
