Outline of Final Research Achievements

We proposed a method for understanding and visualization of various reactions in weakly-ionized plasmas: reaction networks composed of active species generated directly and indirectly in electron-impact collisions. Visualization was performed by a graph whose nodes are tens or hundreds of species and edges bridge chemical agents and products in reactions. With network analysis based of derivation of centrality indices, we identified roles of species microscopically and macroscopically.
