Topological indices Z_2(G)can reflex chemical and physical properties of molecules graphs.
分子图的拓扑指标Z2(G)是反映分子性能的一个重要指标,在文[3]中,我们给出了任一自然数是否可作为某分子图的拓扑指标Z2(G)的一个结论,本文在此基础上讨论了拓扑指标Z2(G)界定的一个递归关系;同时给出了它的一个下界。
Topological indices can reflex chemical and physical properties of molecules statistically.
分子的化学与物理性能一般能用分子图的拓扑指标统计地反映出来。
Inaddition,using the equation of excess Gibbs energy G~E which was correlatedwith the topological index,the binary and ternary solid-liquid equilibria (t-x) for nitrochlorobenzene isomer systems were calculated.
同时,利用表征分子特征的拓扑指标θ关联溶液的过量自由能 G~E。
