Pore diameters and radii are adjusted for the change in thickness of the adsorbed wall
layer during this interval. If new pores were opened during this interval, the average
diameter is adjusted by the change in layer thickness during the second portion of the
desorption interval as:
The layer thickness change during the whole interval is added to diameters of previ-
ously opened pores as:
(not including)
D
avg,k
)
The layer thickness change desorbed during this interval also is added to the radii cor-
responding to the ends of the pressure intervals as:
for all except
Rc
k+1
.
Steps a to c are repeated for each pressure interval.
After the above calculations have been performed, the diameters corresponding to the
ends of the intervals are calculated as:
for all

k+1
.
The remaining calculations are based on

only done for
