We determine the backbone mass distributions for bond percolation between two lines of arbitrary orientations in three … dimensions. All simulations were performed at the percolation threshold pc. The slope of the power law regime of the backbone … mass distribution is dependent upon the angle between the lines, θ, but the characteristic backbone mass is only weakly …

, for site and for bond percolation. We measured their backbone sizes and electrical conductivities. For all sets of … terms for the corrections to scaling of the backbone masses, we would obtain fractal dimensions which are different for site …
