... the kinetic parameters t hat enable such oscillations. The main result of such an analysis is that oscillations arise if t he parameter k 3 is the l argest and the parameters k 6 and k 7 are the smallest ... that can identify the causes of these oscillations. These causes always derive from the influences that concentrations have on reaction rates. The influences reach ove...
