Shengkang Liu, Shuxin Wang, Jirong Jin, et al. Moisture determination for the small sample by thermal neutron[J]. Nuclear techniques, 1982, 05(5): 27-28.
用插入型中子水分计
[1,2]
不能测量小样品和低水分。雷诺兹曾提到用中子透射和散射法可测含氢量
[3]
。塞缪尔用快中子减速透射法测食品水分
[4]
,但要用较强的中子源(10
8
n/s)。考虑到水的热中子截面大,所以我们研究了用热中子测小样品水分的方法。
The methods for measuring moisture of a small sample by thermal neutron transmission and scattering are described
and it is proved to be applicable by the experiment of a small sand-water sample. The devices are also described.
