ON THE RELATIVISTIC FIFTH ORDER GEOMETRICAL ABERRATION EQUATION OF A COMBINED FOCUSING-DEFLECTION SYSTEM
聚焦-偏转复合系统的相对论五级几何象差方程

In this paper, the relativistic fifth order geometrical aberration equation of a combined electric-magnetic focusing-deflection system with superimposed fields is derived by using varia-tional principle and taking symbolic derivative and inner product of complex numbers as mathematical tools.
