Compared the compound porous metal with copper powder sintered porous metal, the results show that the former has smaller shrinkage rate and higher porosity.

结果显示，相比于铜粉烧结多孔材料，泡沫金属与铜粉烧结复合多孔材料具有更小的收缩率及更大的孔隙率。

Geometrical models are built for connected pores of the sintered porous metal. The mechanical compaction force is controlled to obtain the porous metal with the certain porosity.

建立了烧结金属多孔材料连通孔隙形成的模型，通过控制机械压制压力获得了一定孔隙率的金属多孔材料。
