摘　　要：本文叙述了通过分析特征γ射线能谱可以确定待测物质的成分和含量,根据爆炸物所含有的各种化学元素(例如:H、C、N、O)在含量和比率上区别于其它的非爆炸物的这一特点,来判定它的存在。In this article, the experimental research on the detection of explosives with pulsed fast/thermal neutron analysis is introduced. The elemental composition and contents of the tested materials can be determined by analyzing the characteristic gamma ray spectra. The explosives differ in the content and ratio of elements, such as H, C, O and N, from other non-explosives, which leads to their identification.
