摘　　要：根据缓发中子的时间特征行为分析了缓发中子的中子输运过程,讨论了缓发中子探测核弹头的技术与方法。研究表明,测量缓发中子可以有效地探测到核弹头。但在不知道核弹头的内部设计信息的情况下,需用其他方法加以配合才能甄别真假核弹头。In this paper, the time character of delayed neutrons is considered. The method of computing transportation of delayed neutrons is studied. Technology and method of detecting nuclear warheads by counting delayed neutrons are discussed. The results show that a nuclear warhead could be detected by counting delayed neutrons. But, this method could not discriminate the real warhead from the fake one that contains only natural uranium if the design information of the warhead is unknown beforehand. So the joint use of this method with others will be necessary.
