不需引入任何其它假定，就自然解释了Υ→3g三胶子碎裂末态重子多重数增高的重要特征。

计算了e+e-湮没与pp（p）反应过程的直生介子与重子多重数，与经验公式中的参数完全一致。

In this paper the multiplicities of directly producted mesons and baryons in e + e - annihilation and pp ( p ) reaction are calculated and are in complete agreement with the parameter in the experienced formula .

并且理论上对Φ（pt）的起因并不明确，如起伏究竟是由单事件平均横动量和多重数关联n～n引起或由两粒子关联特别是玻色-爱因斯坦关联（BEC）效应引起。

And many disagreements exist in the origin of the fluctuations even in the theoretical aspects , for example whether it comes from ( pt ) n ~ n or from Bose-Einstein Correlation ( BEG ) .

在很普遍的条件下证明了，当碰撞核不很轻，快度窗口不很窄时，多重数n的归一化矩近似等于参与碰撞核子数N的归一化矩。

It is proved under very general conditions that , when the target mass is not extremely light and the rapidity window not very narrow , the normalized moments of the multiplicity are approximately equal to that of the number of participating nucleons .

但3种轻味夸克事例的平均带电粒子多重数近似相等，这与QCD强相互作用与味道无关的预言一致。

But the final average multiplicities of charged particles seem to be equal in three kinds of light q 0 jet events , which shows that our results are consistent to the predictions of QCD , i.e. the strong interaction is irrelevant to the quark flavor .

利用400GeV／cpp碰撞多粒子产生的实验数据计算了QCD分支过程的熵指数，得到了非零值，熵指数随末态粒子平均多重数的减小而增大。
