中能重离子反应后期高激发态核的多重碎裂可用量子统计模型来处理．不稳定的中等质量碎片将再次衰变成新的碎片多重性分布．由反应所发射的各种带电粒子数目间的比率所标志的碎裂度可确定系统的熵，而由粒子不稳定碎片衰变的产额，可确定核系统的温度。 Multifragmentation in the late stages of intermediate-energy heavy ion collisionscan be described with the quantum statistical model. Instable medium fragments undergodecay subsequently, and which would redistribute multi fragment yields. The degree of dissociation, which can be measured by ratios of various charged particles emitted, is proposedas a measure of the entropy of the system. From the yields of the decay of particalinstablefragments to extract the temperature of the system is discussed.
