the burn-up progresses (progressive burn-up). Towards the end of the
burn-up the pressure profile levels out rapidly because the burning
surface area of the powder becomes drastically smaller as soon as
approx. 88% of the powder has been burnt.
Figure 4, which shows the calculated profile of the dynamic liveliness
as a function of p/pmax, again reflects essentially the shape of the form
function for p/pmax > 0.2 (see Fig. 5). On the other hand for small
values of p/pmax, the dependence on p a-1 resulting for a = 0.9 is
dominant. The kink in the shapes of the form function and the dynamic
