What is the difference between fractal dimension determined by surface profilometry and Hg porosimetry?(adsbygoogle = window.adsbygoogle || []).push({});

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
