Some factors affecting the accuracy of uranium content determined by delayed neutroncounting and methods to solve the problems are reported.
文章介绍了用缓发中子计数法测铀时遇到的一些影响测量结果准确度的因素和采用的解决办法。

Inside the sphere cavity, the ratio of ultra thermal neutroncounting rate to thermal one is less than 10%, but the counting rates slightly depend on the position of thermal neutron detector.
球腔内超热与热中子计数比小于10%,计数率依赖于热中子探测器所在位置。
