摘　　要：采用固相微萃取(SPM E)、GC、GC/M S技术,对JOB-9003炸药及Φ10 mm×8 mm小药柱加速老化贮存初期释出气体进行了研究。检测到的气体物质主要包括JOB-9003的各组分生产过程中使用的溶剂和原料、JOB-9003造粒过程中使用的溶剂、JOB-9003的组分、JOB-9003释出物质互相反应的产物。研究表明,JOB-9003加速老化贮存初期释出气体以生产过程中被封闭在材料中或溶入材料中的气体为主。随着贮存温度的升高和贮存时间的延长,JOB-9003造型粉及小药柱释出的各种气体组分的浓度大都呈升高的趋势。Gases released by accelerated aging JOB-9003 molding powder and pellets at different temperatures for 2～4 months and the effect of storage conditions on the amount of gases are studied by means of SPME, GC and GC-MS techniques. The results showed that variety of gases such as toluene, ethyl acetate, 2,4,6-trinitrotoluene （TNT）, 2-chloropropanonitrile and so on could be examined, which derived from raw materials and solvents used in making ingredients between gases released by JOB-9003. The amount of gases increased with the increase of accelerated aging temperature and time.
