摘　　要：通过仿生、分形与材料制备相结合的途径,以天然分形材料海藻作为基底材料,利用化学沉积和电沉积的方法,制备出具有明显分形结构的金属镍,用计盒维数法计算出其分形维数为1.5～1.6.液氮吸附(BET分析)方法的分析结果表明,该材料具有较大的比表面积.A way that manufactured metallic material with fractal structure has been studied through Biomimetics and fractal. Some algae with natural fractal structure were used as the basis foundations. The metal was coated on the foundations by both electroless deposition and electrodeposition. After disposing of foundational algae by erosion, dissolution etc., the pure metallic material with fractal structure was obtained. The fractal dimension of the metallic material was calculated by box-counting dimension. Then specific surface area determination of Ni structure (based on BET analysis) was preformed using nitrogen adsorption.
