What is the difference between fractal dimension determined by surface profilometry and Hg porosimetry?
For example, for a given dataset, say samples 1-5, the backbone fractal dimension determined by Hg porosimetry increases from 2.5 to 3 (the percolation fractality is 3 for all samples).
For Surface profilometry determined on a 2D surface (not a line!) with z as the third dimension, the data is exactly inversed, it decreases from 3 to 2.5
(see example data below)
Why?
What is the difference between the two methods?
thanks.
Data# Hg Profilom.
1 2.5 3
2 2.6 2.9
3 2.7 2.8
4 2.8 2.7
5 2.9 2.5
