摘要：
In this paper, the composite Hermite rule for the computation of the hypersingular integrals on interval is studied and the error expansion is presented. The superconvergence result of the Hermite rule is derived, which is one order higher than general. At last, several numerical examples are provided to validate the theoretical analysis.
