渗透率测量 meaning in Chinese

permeability survey

Regarding the lcm filling process as the newton fluid through fibrous reinforcements , the permeability of preform determines the saturating of resin in fiber , and has effects on the curing process and the quality of products . based on the darcy ' s law , the theoretical model of permeability measurement was established . and the influence of different testing methods and major process parameters such as fabric structure , fiber volume fraction , injection pressure , flow rate and resin viscosity on preform permeability were investigated in details
文中首先根据达西定律建立了渗透率测量的理论模型，深入研究了不同的测试方法及主要工艺参数(纤维织物织构、纤维体积含量、充模压力、流动速度、树脂粘度)对渗透特性的影响规律，发现多孔介质增强材料的渗透率主要取决于纤维织物的结构形式，预成型体孔隙分布及其体积分数、压实性对渗透率有较大的影响，提高充模压力和流动速度可以缩短充模时间，在一定程度上可以提高渗透率。
