the simplest form of the parton and hadron cascade model, paciae1.0, is employed to investigate the charge fluctuation of quark matter and the pauli blocking at the partonic stage of ultra-relativistic nucleus-nucleus collisions and its effect on the hadronic final state 完整部分子和強(qiáng)于級聯(lián)模型,paciae還在進(jìn)一步的完善之中,我們對其物理思想作了較為詳細(xì)的介紹,簡單的部分子模型paciaei刀己用來研究電荷漲落和pauli阻塞等問題。當(dāng)sjeon、v
