  • 本文将文献[1]的方法和结果加以推广,研究了旋转对称静电透镜和磁偏转器的复合系统。给出了场和轨迹的普遍表达式,讨论了高斯光学性质,得出了这种系统普遍的三级象差和象差系数的公式。这两篇文章有助于较全面地研究各种电子束管和电子光学仪器的偏转象差。
    In this paper, a combined system consists of electrostatic round lens and magnetic deflector with additional superimposed fields is studied. The general power-series expression for magnetic deflection fields, the electron trajectories described in vector form and the Gaussian optical characters of the system are obtained and discussed. Formulae for calculating the third order aberration in such a combined system are given in a compact matrix form, they are appropriate for numerical computational purpose. This paper and the previous work [1] are all concerned with the general theory of a combined electrostatic-magnetic system of electron optics, hence they may be useful for designers of cathode ray tubes and electron optical instruments.
