摘　　要：本文给出了用两相微正则系综蒙特卡罗模拟研究高温低密有限核系统破碎过程,得到有关相变行为的结果.上述系统所特有的这些相变行为,是库仑相互作用和有限大小效应竞争的结果.The behaviors of phase transition shown in disassymbly processes of very hot and dilute finite nuclear system have been exposed by using canonical (microcanonical) ensemble Monte Carlo simulation. It is explained that they result from the competition between Coulomb interaction and the effect of finiteness.

关 键 词：有限核系统 破碎过程 相变行为
