Example text

It corresponds to the hatched area in Figure 5. However, the pore volume distribution in Figure 5 (approximately negative exponential decay in shape) refers to a parallel bundle interpretation. It is necessary to deduce the network pore size distribution that gives rise to the same mercury penetration curve. The deduced distribution of pore volume according to a 23 x 23 x 23 network (containing 3 8,000 pores) is presented in Figure I I . Also shown in Figure I I is the parallel bundle result. The shielding of large pores behind small one gives rise to a significant distortion in the parallel bundle result.
