solution porosity

Adding nonsolvent in casting solution was a good measure to increase the effective porosity of membrane, but the nonsolvent content added in casting solution should be high enough to counteract the reverse action caused by casting solution temperature.

在铸膜液中加入非溶剂是提高膜性能的一种手段，但非溶剂的加入量需足够大，以抵消铸膜液温度提高引起的相反的效应。

The vugular pore water distributed over Mesozoic 'Red Beds' in Sichuan Basin, is of peculiar significance in terms of water supply, though its water capacity, varies greatly, as being controlled by the unevenly distributed vugular solution porosity.

分布于四川盆地中生代红层中的溶隙溶孔水，表现为富水性差异大、分布不均匀、受溶隙溶孔网络控制等特征，是盆地内具有特殊供水意义的地下水。

The reservoir of middle porosity and low permeability with solution pore and remainder intergranular porosity is distributed of the point-sandbar deposit and the distributor channel deposit are mainly objective formations of exploration in South Yi-Meng;

其中中孔低渗型储层以溶蚀孔和残余粒间扎为主，多发育于南部三角洲平原分流河道砂体及北部的曲流点坝中，为伊盟地区的主要储集层；

With increasing concentration of NaOH in the solution of the anodizing, the time and voltage of spark formation decrease and particle, porosity, thickness of anodic oxide film become smaller.

阳极氧化过程中，随着NaOH浓度的升高，出现电火花的时间缩短，出现电火花的电压值降低，阳极化膜表面的颗粒变小、孔隙率减小，膜层厚度减小；

Numerical solution of bottom water coning problems in a double porosity medium

双重孔隙介质中底水锥进问题的数值解

For this reason, the simultaneous equations for jointly interpreting the three kinds of porosity logging data are developed by using acoustic logging, density logging and neutron logging data, and they are solved to obtain some formulae of final solution by using Cramer law.

为此，本文利用声波测井、密度测井和中子测井的读数建立了三种孔隙率测井资料解释的联立方程，并用克莱姆法则（Cramer定律）给出最终求解的公式。
