摘要
本文提出以粉末样品直接压饼法测定岩石化探样品中的微量U,Th,其方法简便、快速,适用于各类地质样品,尤其是岩石化探样品测量。
In this paper, powder pellets of petrochemical exploration samples are used to determine the trace uranium and thorium. The analytical method is easy and high-speed, which is saitable for determination of all kinds of geological samples, specially, petrochemical exploration samples.
