摘要
本文从分析影响建立网络状态方程的因素入手,根据网络元件的特性,论证了元件在充当树支、连支时的合理排列次序,按照这个次序作出的树,最有利于导出状态方程,是最佳树。本文还列举算例,根据选出的最佳树,写出拓扑方程,并和元件特性方程进行代入综合运算,很容易地消去不需要的变量,获得状态方程的标准型。与其他方法比较,代入综合法的运算过程简捷,工作量大大减少,兼有直接法和拓扑法的优点。
This paper begins with the analysis of factors affecting the esta-blishmet of network state equations. On the basis of characteristics of networkclement, a rational formntation order of elements as twigs and links is proved.According to the order, a best tree can be drawn, which is helpful to for-mulate state equations, Two examples are enumerated On the basis of the besttree, topological equations of network are written. By inserting operationswith both topological equations and characteristic formulas, a standard stateequation is derived as a result of eliminating the undesired variables. Thismethod is simpler and more convenient as compared with the others in theand has advantage of both the topological method and the direct operations,method.
