Removal-dominated fragment size distribution
= Removal-dominated fragment size distribution
{title2=$n(D)=S_N(D)t_y(D)$}
If fragments are injected with number spectrum $S_N(D)\propto D^{-\alpha_r}$ and escape faster than they collide, steady balance gives $n(D)=S_N(D)t_y(D)$. Thus $t_y\propto D^\gamma$ changes the differential number index to $\alpha_r-\gamma$. A removed population with size-independent subsequent lifetime retains the source index $\alpha_r$.
