Abstract
We show that the recently proposed scaling laws [see G. Zhuang, W. Wang, Ph ys. Lett. A 268 (2000) 413] for chain diffusion on missing-row Pt(110) have no real meaning, since they cannot be extended outside the narrow chain-le ngth range which has been considered by Zhuang and Wang. The only asymptoti c scaling law gives a chain mobility which is inversely proportional to the chain length; however this asymptotic scaling behaviour is not physically important due to the occurrence of multiple upward promotions for long chai ns.
