Steady-state regime

In the steady-state regime, the crack growth rate is described by... 

Biernath et al. concluded that phenolic novolac and epoxidized cresol novolac cure reactions using triphenylphosphine as the catalyst had a short initiation period wherein the concentration of phenolate ion increased, followed by a (steady-state) propagation regime where the number of reactive phenolate species was constant.85 The epoxy ring opening was reportedly first order in the steady-state regime. 

The batch reactor is generally used in the production of fine chemicals. At the start of the process the reactor is filled with reactants, which gradually convert into products. As a consequence, the rate of reaction and the concentrations of all participants in the reaction vary with time. We will first discuss the kinetics of coupled reactions in the steady state regime. 

The existence of pulsating motion of the liquid phase within the catalyst pellet indicates that under certain conditions a steady-state regime of reaction progress can become unstable due to the exothermicity of the reaction under study. Further... 

The results presented by Bagley et al. [45] imply that the oxide diffusion coefficient is much smaller in the steady-state regime than in the diffusion-controlled regime where physical bombardment is absent. It may be possible to account for this effect in terms of the diffusive transport model presented earlier by using a smaller oxide diffusion coefficient in the steady-state regime. To explore this possibility, one may set dX/dt= 0 in Eq. 7 to obtain... 

This form of selectivity applies to sensors that operate in the steady-state regime. The prime examples are thermal and amperometric sensors. It is somewhat limited for potentiometric sensors and it is least suitable for mass sensors. The minimum necessary kinetic background information can be found in Appendix B. 

At low frequencies, it approaches the macroelectrode behaviour. Indeed the steady-state solution shows that the microelectrode can be considered as a simple extension of the macroelectrode. In this quasi steady-state regime, the frequency is small enough to allow the concentration wave to propagate over the whole diffusion layer thickness. 

Existence of a steady-state regime in which the global oxidation rate does not depend on the initiation rate constant. 

Note that the asymptotes of eqn. (18) include characteristics of those unstable regimes near which the motion is delayed. On the other hand, in terms of the "linear approach to relaxation studies one must examine the characteristics of that steady-state regime towards which the motion converges. These two cases differ significantly. 

This PFIEBR operates in a steady-state regime and a volumetric flow rate [49]...
