Research Abstract

Side-branches of dendrites competitively grow with other branches. We have clarified some statistical characters of the side-branches of NH4Cl dendrite growing from the supersaturated solution for the first time as following. The length distributions of side-branches show static and dynamical scaling laws and the multi-fractal spectra considering some measures on both the side-branches and a stem as supports.
