filtration fraction

Significant renal hemodynamic abnormalities , presented as increased glomerular nitration rate ( GFR ) and filtration fraction ( FF ) were observed in 41 cases of NIDDM without proteinuria .

41例无蛋白尿组中已见明显异常，表现为肾小球滤过率（GFR）及滤过分值（FF）增高。

Capillary flow rate , blood apparent viscosity , filtration rate and filtration fraction with dynamical change of tissue pressure were calculated numerically , and were compared with those in static tissue pressure condition .

数值计算了组织压动态变化时的毛细血管流量、血液表观黏度、渗透率和渗透因子，并和静态组织压的相应变量进行比较。
