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。

Adding middle grade sintered magnesia powder can enlarge the line ratio and porosity after high temperature treatment.
中档镁砂粉的添加使浇注料高温处理后的线变化率增大和气孔率增加。
