摘　　要：应用活化法对辐照物引起的CFBR-Ⅱ快中子脉冲堆泄漏中子场的扰动变化进行了实验研究,采用小型活化箔组对典型的辐照样品条件下样品所在位置的中子能谱进行了实验测量,研究比较了没有辐照样品和有辐照样品时中子能谱和关键能段的中子注量率的变化情况。Experiments which activation technique was employed were carried out to study perturbation caused by irradiation samples to the CFBR - II fast burst reactor＇ s neutron field. Neutron spectra were measured by small sets of activation foils on the typical samples in the leakage neutron field of CFBR - II reactor. The neu- tron spectra, thermal and epithermal fluxes with samples were compared with those without samples.
