【摘要】 根据化学平衡原理和图论中的基本概念 ,提出了一种适用于化学平衡计算的赋权有向图。这种有向图具有三个重要性质 :其一 ,边的方向改变则该边的权随着取逆 (取原权的倒数或负值 ) ;其二 ,顺乘逆除 (或顺加逆减 )一条路上的各权得到自起点至终点的累积权 ;其三 ,回路的权等于 1 (或零 )。本文主要叙述这种图的提出及其在化学平衡中的初步应用更多还原

【Abstract】 According to the theory of chemical equilibrium and the basic concept of graph theory, a weighted digraph method for chemical equilibrium calculation was proposed. The directed graph has three important features: the first, changing the direction of this side will make the weight of it reciprocal(that is, to get the reciprocal or negative of original weight); the second, along the direction of directed graph, its weights are to be multiplied, otherwise, to be divided(or along the direction of directed graph, its weights are to be added ,in reverse, to be subtracted) , i.e., all weights of one road are to be multiplied from starting point to terminal point; the third, the weight of circuit is one(or zero). This article chiefly recited the lodgment of this graph and its preliminary application of chemical equilibrium.更多还原
