摘要：

A method is presented for obtaining the various terms in the Rayleigh-Schrödinger perturbation theory to arbitrary order by means of diagrams. The prescription for obtaining the Nth-order correction to a particular zero-order eigenvector is to construct all diagrams of a certain type and associate an operator with each diagram. The method provides for the easy construction and display of Rayleigh-Schrödinger perturbation-theory corrections. The relationship of the present method to other work is discussed.
