摘　　要：应用灰色理论中的ＧＭ（１，１）模型，对气相色谱法中容量因子ｋ＇和温度倒数１／Ｔ之间的关系进行了研究，求出了许多火炸药组分的ａ和ｕ值，并随机预测了几种火炸药组分的ｋ＇值。结果指出，灰色理论完全适用于对气相色谱保留值问题的研究，方法也完全能应用于实际工作中。n this paper the relationship between k'and 1/T in gas chromatography has been studied by using Grey Model(1,1).In gas chromatography, the relationship lnk'=△H/RT+△S'/Ris similar to the time responsible function in Grey Model The values of a and u of a series of explosives were obtained.and their k' s were predicted. The chromatographic conditions were as follows:SE-54 stationary phase, 0. 22mm × 25m fused silica capillary column; column temperature 110℃-220℃; inject port temperature 195℃;carrier gas flow rate: 50 mL/min N_2; FID detector. The precision of Grey Model is high. We came to the conclusion that Grey Model could be completely adapted to the study on problems of retention in gas chromatography. Also, the method would meet applications of practical work completely.
