Two-dimensional zinc metal leaves and cadmium metal leaves have been grown by electrodeposition.The experiment shows that the metal leaves have a characteristic scaling property of interface dimension C besides their Hausdorff dimension D.Analysing these two leaves,we find that both the number of sites N of the leaves and the number of sites adjacent Na,which is not belonging to the interfaces of the leaves,i.e.,the number of nearest-neighbors follow a power-law with the radius of gyration R_(g) as the variable,i.e.,N=R_(g)^(D) and N_(a)=R_(g)^(C) where D~1.60,C~1.55.
