BUU方程的矩展开与核流体动力学方程
徐忠锋 宿金勇
摘 要 通过对Wigner表示下的BUU方程作矩展开,研究了BUU方程零至二阶矩和流体动力学方程及其相应的守恒定律之间的关系.并获知,在两体碰撞占优势的情况下,考虑了局域平衡假设,BUU模型将以核流体动力学模型所替代.
Abstract By the moment expansion of BUU equation in Wigner representation the relations between BUU equation′s moments and nuclear fluid dynamic equations and their conservation laws are investigated.From this it is known that BUU Model will be replaced by nuclear fluid dynamic model under conditions of dominating in two-body collisions and the (((local equilibrium approximation)))!
