摘要：

We discuss the chemical ordering of the icosahedral phases by considering the atomic local environments in physical space generated by a set of global atomic surfaces. Each kind of local environment corresponds to a 'cell' in the atomic surfaces. From the exploration of the cell decomposition induced by the first neighbours shell in the case of AlCuFe-type icosahedral structures, we conclude that the chemical order in these structures should also depend on the second neighbours shell.
