Because the techniques of the biochemical waste treatment are very important, the techniques of the cultivation of the microorganism have received more attention in recent years. A study is conducted to analyze the steady states and dynamic bechavior of the reactions of the cell-substrate and the prey-predator interaction in two chemostats in series. For the reaction of cell-substrate in two chemostats in series, if the specific growth rate of the Monod model is used for the cell , there are three types of steady states for this reaction system. These three types of steady states and stability are analyzed in detail. The dynamic behavior of this reaction system is analyzed by the numerical method and computer graphs. The results show that the dynamic behavior of this system consists of stable steady states.

由於生物废弃物的处理技术相当重要，故最近几年来微生物的混合培养技术深受大家的重视，本研究实施菌类－基质(Cell-Substrate)和被捕食者－捕食者(Prey-Predator)相互作用之生化反应在两个生化反应槽串联之稳定状态和动态分析，对於菌类－基质之生化反应，若以Monod模式来表示菌类之比生长速率，则此两个生化反应槽串联之反应系统共有三种型态之稳定状态，本研究对此三种型态之稳定状态和稳定度作深入的分析，对於此反应系统之动态行为，则由电脑运用数值分析的方法及电脑绘图进行分析工作，动态分析的结果显示此生化反应系统之动态行为，以稳定之稳态为主。
