摘　　要：研究了以五氧化二磷为干燥剂测定空气含水量的方法,详细论述了该方法的仪器设计、组装、干燥剂的充装、干燥剂的使用周期及现场环境等因素。对硫酸吸收法和本法进行了对比,认为五氧化二磷测定法精密度和准确度均较高,适用于常规中控分析。The present article has investigated the method of measuring air moisture by using phosphorus pentoxide as dryer. In the present article, the effect factors, including apparatus design, apparatus assembly, filling of dryer, use cycle of dryer, and environmental conditions etc., have been described in detail. It has also made a comparison between the method of present article and the method of absorbing by using sulfuric acid. Finally ,a conclusion has been gotten： the method of measuring by using phosphorus pentoxide has a superior precision and accuracy, and it applies to the routine semi-control analysis.
