摘　　要：针对复杂物理系统难以直接构造QSIM定性模型的问题,给出一个基于组件连接的QSIM建模方案─QSIM-CC系统。该系统通过对具体物理系统进行结构分析,建立组件连接模型,进而转化为用于QSIM仿真的定性微分方程(QDE)。组件连接模型的引入,在物理实体和定性微分方程之间建立起一个桥梁,通过形式化的描述,使得QSIM模型的建立更加直观和形象。最后通过一个液压系统的例子,用QSIM-CC构建单体水槽定性仿真模型,并给出其仿真结果。The component-connection method was introduced to solve the problem of constructing QSIM models from a complex physical system directly. A QSIM modeling system named as QSIM-CC system based on component-connection was proposed accordingly. By analyzing the structure of specific physical system, the component-connection model was built, and it could be translated into the qualitative differential equation （QDE） for QSIM algorithm. The component-connection model could establish an efficient relationship between QDEs and the physical system, which made it easier to build the QSIM model from a complex system. An example of hydraulic pressure system was given in the end to build a qualitative model of a single tank system based on QSIM component-connection mechanism, and the simulation results were given finally.
