Stability analysis using describing function conditional

To evaluate the hydrolytic stability of the resin samples, thin layers of the liquid resins were aged at 60°C and 96% relative humidity. The resins were sampled periodically and HPLC was used to monitor the formation of hydrolysis products as a function of aging time. The HPLC operating parameters were similar to those described previously for reverse phase analysis except for the mobile phase conditions which are shown below ... 

The present monograph is intended as a contribution to the theory of the differential equations describing chemically reacting systems. The main topics treated are the a priori bounds and the existence of solutions, the conditions for uniqueness and stability of solutions and the asymptotic behavior of solutions. Most of these problems have been treated by using methods from nonlinear functional analysis and especially fixed point methods. The closely related theory of bifurcation points seems to hold promise for further progress.
