利用同位旋相关的量子分子动力学模型，对~Ｃａ＋~４０Ｃａ和~４０Ａｒ＋４０~Ａｒ系统在不同入射能量时，同位旋效应对多重碎裂的影响进行了讨论．低能区的多重碎裂由于多种同位旋相关的因素相互抵消，因此多重碎裂的同位旋效应不明显．随着能量的增加，同位旋相关的截面造成多重碎裂的明显差别．
The isospin-dependent quantum molecular dynamics model is used to study the effect of isospin effects on multiple fragmentation at different incident energies of ~ Ca + ~ 40Ca and ~ 40Ar + 40 ~ Ar systems. Multifragmentation in low energy regions The isospin effect of multiple fragmentation is insignificant as multiple isospin-related factors cancel each other out. As energy increases, isospin-related cross-sections result in significant differences in multiple fragmentation.
