摘　　要：在自行设计的水泥屏蔽体中，用铀裂变室研究了反射中子测量技术。在不同实验系统上，测量了铁球壳表面不同位置上中子引起的绝对裂变反应率分布。实验总误差为３．９％。In a cement shielding designed by ourselves, technique for measuring reflection neutrons was studied by using the depleted and enriched uranium fission chambers. In different experiment systems, absolute fission reaction rates, derived from reflection neutrons, at different positions of the surface of an iron spherical shell were measured. The experimental error was about 3.5%-4.1%.
