Concentrations of free copper and mucus and other parameters including pH and alkalinity of the gill microenvironment of Cyprinus carpio exposed to copper of various levels were determined using Playle's apparatus. 利用Playle设计的装置测定了不同铜暴露水平下鲤鱼鳃部进出水中的游离铜离子浓度、粘液含量及有关参数。
Discussion of the Determination of Free Alkalinity in FCC Gasoline Caustic Sludge 催化汽油碱渣游离减度的定量问题探讨
Free alkalinity is mainly related to the CaO quality and quantity in process of adding processing. 4. 游离碱度主要和加工过程中添加的石灰质量和用量有关。
