本文论证了对赝标介子与核子耦合的理论,齐次Callan-Symanzik方程可用来得到电磁形状因子的渐近行为。由此得到这个理论中核子电磁形状因子的微扰论领头项,并讨论了较一般的情形。It is shown that for the model in which nucleons couple with pseudo-scalar mesons, the homogeneous Callan-Symanzik equation can be used to investigate the asym-pototic behavior of electromagnetic form-factors of the nucleons. In this way, the leading-logarithm terms in the perturbation theory of electromagnetic form-factors of the nucleon in this model are calculated, and some more general cases are discussed.
