General Solution of Kinetic Problems

As stated above, the analytical solution of the hydrogen combustion problem, even at constant temperature, is only possible for a simplified reaction mechanism. The effects of certain simplifying assumptions on the results of the solution of the problem have been discussed in [15]. 

For the general case studied, only numerical computations are possible. 

Inside the ignition peninsula, of great importance is also the process O -f OH - Og + H, not included into the simplifed mechanism. 

Leaving aside individual reactions, mention will be made here only of one of the methods commonly used at present. This method involves elimination of time from the kinetic equations and attempts at finding stable solutions in terms of the Lyapunov stability theory. In the simple case of two variables X and Y (e.g. of two active centers, or of one active center and temperature), from the kinetic equations dx/dt = y) dy/dt = y(x, y) (x and y are either
