论文摘要
我们证明了在质量独立的翻新方案中。与表征重新归一化方案和质量量表的非物理参数相关的重新归一化组方程会导致求和，从而导致对这些参数的隐式和显式依赖性之间的取消。因此，所得的扰动扩展与这些任意参数无关。我们通过考虑r（e+e--> hadrons的横截面）来说明这一点。
We demonstrate that in the mass independent renormalization scheme. the renormalization group equations associated with the unphysical parameters that characterize the renormalization scheme and the mass scale leads to summation that results in a cancellation between the implicit and explicit dependence on these parameters. The resulting perturbative expansion is consequently independent of these arbitrary parameters. We illustrate this by considering R, the cross section for e+e- -> hadrons.
