摘　　要：在ADS次临界中子学研究中,将次临界外堆法和超临界周期法相结合,实验测量了模拟ADS次临界装置中心布置不同缓冲区材料时的有效增殖因子keff和缓冲材料所相当的反应性。实验结果与其它实验方法的结果进行了比较,相互符合较好。The sub-criticalties of ADS model facility with water, Pb and stainless as buffer region were measured by the use of extrapolation period method. The reactivity of buffer region were also given. The results between this method and other experiments are well agreed.
