甲烷等分子气体的化学反应非常复杂，以至于等离子体中分子的分解和/或合成物种图表类似于一个网状网络，我们在其中记录物种和它们之间的反应。在这里，我们考虑甲烷等离子体中化学反应的网络结构的特性。在网络中，假设原子/分子/自由基物质形成节点，化学反应对应于图论术语中的有向边。对中心性指数的研究揭示了 CH3 在整体化学反应中的重要性，并且有电子和无电子情况下每个自由基物种的指数差异表明电子处于收紧网络结构的影响力位置。
Chemical reactions of molecular gases like methane are so complicated that a chart of decomposed and/or synthesized species originating from molecules in plasma resembles a weblike network in which we write down species and reactions among them. Here we consider properties of the network structures of chemical reactions in methane plasmas. In the network, atoms/molecules/radical species are assumed to form nodes and chemical reactions correspond to directed edges in the terminology of graph theory. Investigation of the centrality index reveals importance of CH3 in the global chemical reaction, and difference of an index for each radical species between cases with and without electrons clarifies that the electrons are at an influential position to tighten the network structure.
