摘要：
We describe how a, reduction technique can be applied to a chemical model of a typical protoplanetary disk in order to determine the primary chemical processes, relevant to the evolution of the disk ionization degree. It is shown that the number of involved species and reactions significantly varies throughout the disk, serving as a direct indicator for the chemical complexity. Additionally, we discuss where in the disk the chemical equilibrium approach can be used to compute the fractional ionization.
