文摘Asymptotic expansion of two Sheffer polynomials, namely, Charlier and Laguerre, was obtained by L，C， Hsu6]using a combinatorial method， In this paper, L，C， Hsu's method in [6]has been put into a formal theorem that the author successfully applied to four other Sheffer polynomials: Poisson-Charlier, weighted Touchard, Toscano, and Angelescu polynomials， Within sonic specified domains remainder estimates have been obtained， Moreover, sonic spplicability and llimitation have been mentioned，
