摘　　要：混杂系统是对一些复杂系统的抽象模型。可观性是系统的重要属性。混杂系统的可观性分为:离散状态的可观性和连续状态的可观性。一般最终状态可观性是混杂系统离散状态可观性的一个合适的定义。给出了一个算法,计算确定混杂系统离散状态所需最小输入串长度。Hybrid system is an abstract model of complex systems. Observability is a important attribute to systems. Observability of hybrid systems can be devided in to observability of continuous state and of discrete state. In general, the final state observability is a suitable definition of obervability of discrete state. The parer gives out an arithmetic calcultion for input event serial length. The method determines the least serial length, needed for determination of descrete state in hybrid system.
