摘　　要：提供了气相色谱法测定火药中硝化甘油含量的方法,火药样品经丙酮和苯二甲酸二乙酯标准液萃取。经离心沉淀后,采用SE-30填充柱分离,用TCD检测器测定,方法回收率在95.0%~99.2%之间,测定结果的相对标准偏差（n=6）在1.8%~2.3%之间。The content of nitroglycerine in the propellant was determined by GC with TCD.The sample was extracted with acetone and diethyl phthalate.After precipitation by centrifugation,it was separated on SE30 micro-packed column.Test for recovery was carried out by standard addition method,the recovery was in the range of 95.0%~99.2%.The RSD（n=6） was in the range of 1.8%~2.3%.
