摘　　要：叙述了采用多种屏蔽过滤方法,通过实验获得多种条件下的中子注量率能谱的调节和测量。Shiel ding-Experimental Reactor of Tsinghua University is a multifunctional reactor. It possesses a huge radiation channel of 1mx 1mx 0. 7m. According to different requirements of users, various shielding filter materials were used to adjust neutron flux spectrum. Active foils, HPGe y spectrometer, general SANDⅡ method were exploited to calculate and measure the neutron flux energy spectrum to satisfiy requirements of users.
