摘要：

The reparameterization invariance in Heavy Quark Effective Theory is reconsidered. Starting from an effective Lagrangian derived from QCD full theory, a consistent transformation law for the heavy quark effective field under the variation of the parameter v is obtained and the reparameterization invariance in the effective Lagrangian is shown.
