结果表明：微孔阴极中的颗粒连通性好、颗粒尺寸小以及孔隙率高都有利于电脱氧的进行。
The results show that small particle size, good connectivity among particles and high porosity of the cathode enhance the rate of electro-deoxidation.
孔隙类型以粒间孔为主，喉道类型以点状、片状和弯片状喉道为主，连通性一般。
Pore types are mainly intergranular pore, throat types are mainly point, plates and curved sheet throat, general pore connectivity.
实验结果表明：直接电脱氧法制备金属镝工艺是可行的，微孔阴极中的颗粒连通性好、颗粒尺寸小、孔隙率高均有利于电脱氧进行。
The results showed that small particle size, good connectivity among particles and high porosity of the cathode could enhance the rate of electro-deoxidation.
