摘要：

In the simple model of interacting pseudoscalar and fermion fields it is demonstrated that using an appropriately chosen renormalization condition one can have consistent power counting for multi-loop diagrams within the relativistic baryon chiral perturbation theory. Explicit calculations are performed for a two-loop diagram contributing to fermion self-energy.
