Measurement of the steady and non - steady - state chloride diffusion coefficients in a migration test by means of monitoring the conductivity in the anolyte chamber comparison with natural diffusion tests 很多混凝土科学工作者都在积极努力的发展氯离子传输和检测理论及试验室方法，目前理论及试验室检测标准众多，但尚无明确的现场检测标准。

( i ) in the procession of preparing na2feo4 by electrolyzing and oxidizing anodic iron in the high concentration solution of naoh , the current efficiency is directly proportional to both of the temperature and the alkaline concentration of the anolyte , and the growth rate of the na2feo4 concentration of anolyte is directly proportional to both of the electrolyzing speed and the alkaline concentration of anolyte . , 主要结论如下： ( 1 )在浓naoh溶液中直流电解氧化铁阳极生成na _ 2feo _ 4溶液的过程中，电解液温度、阳极液碱浓度与电流效率成正函数关系；电解速度、阳极液碱浓度与阳极液中na _ 2feo _ 4浓度的增长速度成正函数关系。
