摘　　要：本文分析了η－η＇混合角和Ｌ＝１介子产生对本态η－η＇多重数比率的影响．计算结果表明，Ｌ＝１介子的产生对比率影响很重要，考虑这一因素后就能得到与实验一致的多重数比率．We analyse the effects induced by η-η'mixing angle and the production of L= 1 mesons on the multiplicity rates of η and η'mesons.The results show that the influence of the production of L=1 mesons on the multiplicity rayes is quite importment.When we take only this factors into account,the calculated multiplicity rates are agreement with experiment.
