摘      要：The mechanical properties and structures of fish scales have generated considerable research interest,however,comparative studies for different fish scales from difl^rent water regions have not been *** this paper,the surface morphologies,hierarchical structures and mechanical properties of four kinds of fish scales collected from freshwater,shallow sea,and deep sea in New Zealand are *** results indicate that the surface morphologies of those fish scales are similar at ventro-lateral,dorso-lateral and anterior locations,and the hierarchical structures of those fish scales all consist of two layers:a bone layer and a collagen layer composed of collagen ***,the spiral angles of the collagen lamellaes of different scales are *** largest are Mugil cephalus scales,while the smallest are Cyprinus carpio *** the mechanical behaviors of those fish scales,the tensile strength of Carassius auratus scales is the largest,but the ductility is the *** sieboldii scales have the best ***,the relationship between hierarchical structures and mechanical properties of fish scales is *** is found that the spiral angles of the collagen lamellaes and bond/collagen thickness ratio both have a great influence on the mechanical properties of fish scales.
