摘　　要：依据多年生产实践，提出“环生假想”。在此假想的引导下，以重量含量为３％的扩孔剂水溶液常温处理０．５ｈ，可将拟薄水铝石的孔容从０．３６ｍＬ／ｇ提高至０．５２ｍＬ／ｇ。According to production practice for long years,the ring-forming hypothesis was originated.Under the guidance of this hypothesis,the psedoboehmites are processed by aqueous solution containg 3 wt.% reaming agent at atmos-pheric temperature for 0.5h, thus increasing their porosity volume from 0.36 to 0.52mL/g.
