| 摘 要： | 基于Druce等人的方法,提出了一种新的g玻色子效应重整化微扰论方法.对使用此两种方法的前提条件一弱耦合条件,作了考察,并给出了满足前提条件下,两种方法的g玻色子效应的重整化计算结果.对比分析表明,提出的方法克服了Druce等人方法的局限性,对g玻色子效应的考虑更充分.

| Abstract: | An approach based on purturbation theory is proposed to renormalize g-boson effects for sdglBM system, which modifies that presented earlier by Druce et al. The weak coupling condition as the usage premise of the two approaches is proved to be satisfied. Two renomalization spectra are calculated for comparison and analyses. Results show that the g-boson effects are renormalized more completely by the approah proposed in this paper. |
