摘要通过复合电磁同心球系统的理想模型,对成像电子光学近轴方程的轨迹求解进行探讨。首次推导了该系统的近轴电子轨迹的转角及近轴方程的两个特解的解析表达式,探讨了近轴成像性质,并将结果推广到两电极静电同心球系统、均匀平行复合电磁系统和静电近贴系统中。 The ray solutions of paraxial equation for imaging electron optics have been explored by an ideal model of combined electromagnetic concentric spherical system in the present paper. The exact analytical expressions of rotational angle as well as two special solutions of paraxial equation in this system have been firstly derived, and the paraxial imaging properties have also been investigated. The results have been generalized to the bi-electrode electrostatic concentric spherical system, the homogeneous and parallel combined electromagnetic system, and the electrostatic proximity system.
