摘　　要：给出了一组由系统的定性结构描述及初始状态导出定性行为的形式定义,并提出了一种新的定性模拟算法 QSIM(Qualitative Simu-lation).QSIM 能有效地导出系统的定性行为描述,预测出系统原先未知的某些临界值及其对应值.文中举例说明了 QSIM 的应用.In this paper,a formal definition of deriving the qualitative beha- vior description of a system from the qualitative structure and initial state of the system is given,and a new qualitative simulation algorithm QSIM~* is proposed.The QSIM~* not only can predict the unknown landmark values of some parameters in a system,but also can derive their correspondences. Finally,the paper demonstrates the application of QSIM~* to a simple spring system.
