摘　　要：膨化硝铵炸药中加入柴油,在降低返粉率的同时,也降低了炸药性能。在炸药爆炸基本理论和科学试验的基础上,分别研究了柴油配比与炸药性能及返粉率的关系,绘制了关系曲线,最后通过分析三者的综合关系,得到了确定最优柴油配比的方法。研究结果表明:炸药的氧平衡、爆热和爆速均随柴油配比的增加而降低;返粉率曲线可分为AB(返粉率明显下降)、BC(不明显下降)和CD(维持定值)三个阶段;柴油配比不应超过10%;当qmax处于CD之间时,柴油配比应取C值,处于BC之间时,柴油配比取值应尽量接近B值,处于AB之间时,柴油配比应取qmax。Adding diesel into expanded ammonium nitrate explosive could decrease the return fine rate,but which also decreased the explosive performance. Based on the basic theory and scientific tests of explosive explosion, the relationship between the diesel ratio and the explosive performance,as well as the return fine rate was studied. At the same time,the relationship curves were drawn. Finally,by discussing the comprehensive relationship,the method to determine the optimal diesel ratio was obtained. The results showed that,with the increase of diesel ratio,the oxy-gen balance,heat of explosive and detonation velocity were decreased;the return fine rate curve was divided into three phases as AB（ decline obviously）,BC（ not remarkably）and CD（ maintain）;the diesel ratio should be less than 10%;when qmax was in CD,the diesel fuel ratio should be taken as the value of C;when it was in BC,which should be taken as close to the value of B;and the value of qmax should be taken when it was in AB.
