摘要

By virtue of the technique of integration within Weyl ordered of operators we derive the formula of Weylordering expansion of power product of coordinate and momentum operators (21/2Q)m (21/2iP)r =∷Hm:r(21/2Q,21/2iP)∷,the introduction of two-variable Hermite polynomial Hm,r brings much convenience to the study of Weyl correspondence.
