【Abstract】 The concrete analytical expressions of axial third order aberration coefficients of circularelectric field are automatically derived by computer. A software package used here is programmed with artificial intelligence language Arity Prolog. A brief introduction presented about the course of aberration coefficient by the software package. The results can be used to project design and engineering calculation.更多还原
