The liver perfusion parameters including hepatic blood flow(BF), blood volume(BV), mean transit time(MTT), permeability surface area product(PS) and hepatic arterial fraction (HAF)was calculated.
通过扫描软件得出肝血流量（BF）、血容量（BV）、对比剂平均通过时间（MTT）、渗透表面积乘积（PS）、肝动脉灌注指数（HAF）。
This fractures the rock, creating "enhanced natural permeability" and exposing a large surface area of hot rock.
这将使岩石碎裂，创造一种“强化的自然渗透率”并进一步使大面积的热岩区域暴露出来。
The distribution of pore surface area is mainly in micro and transitional pore; the pore connectivity is poor and the permeability of coal seam is extre…
孔隙率较高，孔比表面积主要分布于孔径较小的微孔和过渡孔段，孔隙的连通性较差，煤层渗透率极低；
Generally speaking, the smaller Porosity, the more dense rock, the greater surface area, the lower permeability, the more serious the adsorption phenomenon is.
总体而言，孔隙度越小，岩石越致密，比表面越大，渗透率越低，吸附现象越严重。
Filtration media is required to have suitable pore size, pore size distribution, pore volume, pore surface area and permeability for performing satisfactorily in applications.
为使过滤材料在使用中达到令人满意的性能，要求过滤介质具有适宜的孔径尺寸、孔径分布、孔体积、孔表面积及渗透性。
