摘　　要：通过采用一个新的非微扰参数化对核子散射重整化进行了初步分析,指出传统重整化方法中的困难与问题,并通过唯象的方式显示了非微扰框架下的重整化方案对理论预言的影响,突出了适当的边界条件对重整化方案的重要性.The renormalization of nucleon scattering is studied in nonperturbative regime. The failure of the conventional subtractive program in nonperturbative context is analyzed. The nontrivial relevance of renormalization prescriptions in calculating phase shift and the importance of physical boundary conditions in determining the choice of the prescriptions are discussed in the nonperturbative parametrization and illustrated with an example in the partial wave channel .
