多元可逆反应网络系统颇常见于石油化学及生物化学,通常表现具有三边形或四边形结构(图1),或由这些结构组合而成;二氯丁烯的三种异构体:3,4二氯丁烯-1,顺式1,4二氯丁烯-2,反式1,4二氯丁烯-2在催化剂作用下的互变异构即为一个三边形结构。该类网络最一般的情形为图2所示的多边形结构,其可能发生反应数的极限为N(N-1)。 Multivariate reversible reaction network systems are quite common in petrochemistry and biochemistry, and usually exhibit a triangular or quaternary structure (Figure 1) or a combination of these structures; three isomers of dichlorobutene: 3,4 The tautomerism of dichlorobutene-1, cis-1,4-dichlorobutene-2 ​​and trans-1,4-dichlorobutene-2 ​​under the action of a catalyst is a triangular structure. The most common case for this type of network is the polygon structure shown in Figure 2, where the limit of the number of reactions that can occur is N (N-1).
