【摘要】 本文研究了气流分级过程中的“鱼钩效应”；指出颗粒间团聚是产生“鱼钩效应”的一个重要的原因，并对原有的分级模型进行了修正，给出“鱼钩效应”的理论计算式。最后还根据实验结果分析了影响“鱼钩效应”的各种因素．更多还原

【Abstract】 The Fish-hook effect in air classifiers is stucdied in theis paper. It is found that agglomeration is the main origin of the fish-hook effect. Based on the former model of airclassifying process, a revised model is given to simviate the fish-hook effect, and atheovretical formula is developed. Finally,it also analyses the factors which can affect theshape of the fish-hook.更多还原
