摘要
本文通过水泥厂粉尘卫生防护距离的计算实例，比较、分析了国标推荐的两种计算方法的结果．表明ＧＢ／Ｔ１３２０１－９１计算较ＧＢ３８４０－８３结果偏高．进一步分析说明，ＧＢ３８４０－８３方法缺点在于当污染源等效半径超过２００ｍ时，缺少最大防护距离与规化源强间的对应数据．而ＧＢ／Ｔ１３２０１－９１方法的缺点在于未考虑污染源与居住区的空间关系．
In this paper,the results of two methods of national standard by calculating examples of sanitary protective distance of 'cement dust are compared and analyzed. The result expresses that the'calculation result with GB/T13201 is higher than that with GB3840--83. It is apparent that disadvantage of GB3840--83 is short of Lin--or corresponding data when r outstrips200 meters. But disadvantage of GB/T13201 -- gi is short of space relationship of pollution soruce and residential area.
