对中能重离子碰撞的两体关联输运理论、它的Ｈｉｅｒａｒｃｈｙ截断和守恒定律进行了研究．该理论包括了时间相关的平均场、两体关联和Ｐａｕｌｉ原理，并且时间相关的平均场和两体关联动力学之间在自洽耦合和非耦合两种情况下进行了数值计算和讨论．初步计算结果表明，两体关联输运理论能对重离子碰撞动力学过程进行合理的描述，总粒子数、总动量和总能量基本上守恒，从而表明该理论是一个很有发展前景的输运理论．
The theory of two-body transport associated with heavy ion collisions, its Hierarchy truncation and conservation laws were studied. The theory includes the time-dependent mean field, the two-body correlation and Pauli’s principle, and the time-dependent mean field and the two-body correlation dynamics are calculated and discussed in both self-consistent and uncoupled cases. The preliminary calculation results show that the two-body transport theory can reasonably describe the kinetic process of heavy ion collisions, and the total particle number, total momentum and total energy are basically conserved, indicating that the theory is a promising transport theory.
