摘　　要：本文叙述了用两个硅半导体探测器测量~3H(d,n)~4He 反应中子平均能量的方法,并将所得结果与用^(58)Ni(n,p)^(58m+g)Co 和^(58)Ni(n,2n)^(57)Ni 反应截面比测定的平均中子能量做了比较.The method of determination for average neutron energy from ~3H(d,n)~4He reaction by using two silicon semiconductor detectors is described.The result obtained is compared with the result determined by the crosssection ratios of ^(53)Ni(n,p)^(53m+g)Co and ^(53)Ni(n,2n)^(57)Ni reaction.
