摘要: 从热力学关系，计算来自相对论性核-核碰撞的富重子夸克-胶子等离子体的初值.接着基于(3+1)维相对论性流体力学模型研究了系统的双轻子产生.发现随着碰撞核入射能量的增加，一个标志夸克-胶子等离子体形成的特征平台出现在双轻子的总产额中.这样的特征可在CERN和Brookhaven未来的实验中得到检验.

Abstract: From thermodynamic relations, the initial values of the quark-gloun plasma from relativistic nucleus-nucleus collisions are obtained. From these initial values we have studied the dilepton production on the basis of the (3+1) dimensional relativistic hydrodynamic model established by the present authors, and found that with increasing incident energy a characteristic plateau indicating the formation of quark-gluon plasma appears in the total yield, which may be tested in future experiments in CERN and Brookhaven.
