摘要

本文采用新的时间像差定义

考察了"Tau变分法"研究电子光学成像系统的时间像差理论.本文表明

"Tau变分法"所给出的以微分方程形式表示的几何时间像差系数

亦可获得积分形式的表示式

证明了"直接积分法"与"Tau变分法"这两条途径殊途同归.

Abstract

By the use of a novel definition of temporal aberrations

the temporal aberration theory of electron optical imaging system was again investigated by the "Tau-Variation Method".Results show that the expressions in integral form can also be obtained by the "Tau-Variation Method" which usually needs to solve the differential equations for the three of geometrical temporal aberration coefficients of second order.It also proves that the "Direct Integral Method" and "Tau-Variation Method" reach the same goal by different ways.
