摘要
为增加基于核四极共振(NQR)技术探测爆炸物的种类,对黑火药的NQR特性进行了研究。介绍了探测方案的设计与实现,掌握了黑火药NQR共振频率等参数及试验方法。实际测试表明,探测结果准确,从而也为今后NQR技术的扩展应用打下了基础。
In order to increase types of explosives detection based on nuclear quadrupole resonance(NQR),the detection method on black powder is researched in this paper.The results include NQR frequencies and some important detection parameters.Practical test shows this method is precise,so it is very useful to expand the application about NQR technology in the near future.
