The sum of the photopeak and the first escape peak was selected as a characteristic energy window using BGO detector in the spectrum processing, while the sum of the photopeak, the first and the second escape peaks was selected using NaI ( Tl) detector. 在谱处理过程中BGO探测器选择光电峰和第一逃逸峰的和作为特征能窗,而NaI(Tl)探测器以光电峰和第一、第二逃逸峰的和作为特征能窗。
Based on the typical X-ray fluorescence spectrum of the CDBS or CSA containing ANE, XRF tracing detection of the explosive was performed by detecting the escape peak of the characteristic K_(α 1) peak of rare earth element. 根据含CDBS和CSA的AN炸药的典型X射线荧光能谱,提出了用稀土(XT)的Kα1峰的逃逸峰作为检测AN炸药的特征峰,其值为6.11keV。
The reason to fall in local peak was analyzed, and the method to escape from local peak was advanced. 分析了蚁群算法陷入局部最优的主要原因,根据算法陷入最优的原因提出一种判断局部最优的方法;
