Hursts exponent of radial distribution functions(RDFs)within the short-range scope of In,Sn and In-40 wt％Sn melts are determined by the rescaled range analysis method.Hursts exponents H are between 0.94 and 0.97,which display long-range dependence.Within short-range scope,the number of particles from a reference particle belongs to fractional Brownian motion.After RDF serials are randomly scrambled,Hursts exponents all dramatically dropped,which proves long-range dependence.H irregularly varies as the temperature rises,but the change tendency is not consistent with the correlation radius rc.
