摘要：

The HQET and NRQCD Lagrangian is computed to order alpha(s)/m(3). The computation is performed using dimensional regularization to regulate the ultraviolet rind infrared divergences. The results are consistent with reparametrization invariance to order 1/m(3). Some subtleties in the matching conditions for NRQCD an discussed.
