【Abstract】 In this paper the concrete analytical expressions of third order aberration coefficients of an in- homogeneous magnetic sector field are automatically derived by computer using software package programmed by artificial intelligence language Arity Prolog. The results can be used to engineer- ing design and calculation for high performance inhomogenous magnetic sector field analysis device and deflection device directly.更多还原
