Then, the bulk density, porosity, the type of pore, particle constitute and organic carbon in the soil affected the soil moisture diffusivity.

土壤颗粒组成、容重、有机质、孔隙率影响土壤持水性能。

The particle diameter selection then depends on the porosity, pressure drops, and plate strength.

合适颗粒直径的选择与孔隙率、压降和强度的要求有关。

The results show that small particle size, good connectivity among particles and high porosity of the cathode enhance the rate of electro-deoxidation.

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。
