porosity
常考释义
n. 孔隙度;孔隙率【地质】
But note that porosity is not the same as permeability, which measures the ease with which water can flow through a material; this depends on the sizes of the individual cavities and the crevices linking them.
但需要注意的是,孔隙度与渗透率是不同的;渗透率衡量的是水渗透物质的难易程度,它取决于与单个空隙以及连接孔隙间裂缝的大小。
After that, a layer of nickel was electrodeposited on the opal, which was then etched away. The porosity of the nickel layer was then increased using electropolishing.
然后,在猫眼石结构表面用电沉积法镀上一层镍膜,之后把猫眼石蚀刻掉,再经过电解抛光,增加这些镍膜空隙度。
n. 多孔性
