摘要
介绍了一种新的解谱法,它建立在中子谱的先验信息与中子谱的积分数据基础上. 利用先验谱对真实中子谱导数协方差极小,求得结果谱. 结果谱稳定,在探测响应灵敏区内,结果谱对初始谱的依赖性也是很弱的.
A new method based on the prior-knowledge and integral data of neutron spectrum is introduced and it utilizes the minimum of derivative covariance of the prior-spectrum with respect to real spectrum . The result抯 spectrum is stabilized. In the responsive sensitive zone of detectors , result抯 spectrum is poor dependent on the primal spectrum.
