In the study of chemical graph theory, an enormous number of research analyses have confirmed that the characteristics of chemicals have a nearby connection with their atomic structure. Topological indices were the critical tools for the analysis of these chemical substances to consider the essential topology of chemical structures. Topological descriptors are the significant numerical quantities or invariant in the fields of chemical graph theory. In this study, we have studied the crystal structure of copper oxide (Cu2O{{\rm{Cu}}}_{2}{\rm{O}}) chemical graph, and further, we have calculated the ev-degree- and ve-degree-based topological indices of copper oxide chemical graph. This kind of study may be useful for understanding the atomic mechanisms of corrosion and stress–corrosion cracking of copper.

基于ve度和ev度的铜矿Cu 2 O晶体结构的拓扑性质

在化学图论的研究中，大量的研究分析已经证实，化学物的特性与其原子结构有着密切的联系。拓扑指数是分析这些化学物质以考虑化学结构的基本拓扑的关键工具。拓扑描述符是化学图论领域中的重要数字量或不变量。在这项研究中，我们研究了氧化铜（Cu2O {{\ rm {Cu}}} _ {2} {\ rm {O}}）的晶体结构，此外，我们还计算了ev-和基于度的氧化铜化学图拓扑指数。这种研究对于理解铜的腐蚀和应力腐蚀开裂的原子机理可能是有用的。
