一、引言中子活化分析方法自从1950年被应用到地质科学上以来,迅速地在这门科学中起到了很大的作用。近年来,这一分析技术在我国铀矿地质研究中已起到了一定的作用,随着地质科研的发展,对岩石、矿石中各元素的分析要求越来越高。中子活化分析具有灵敏高、使用样品少、可同时测定多种元素等优点。因此,为解决单矿物及少量样品的多元素分析和建立岩石和矿石的管 I. INTRODUCTION The method of neutron activation analysis has rapidly played a large role in this science since it was applied to geology in 1950. In recent years, this analytical technique has played a certain role in the study of uranium geology in our country. With the development of geological research, the analytical requirements of various elements in rock and ore are getting higher and higher. Neutron activation analysis with high sensitivity, the use of samples less, the simultaneous determination of a variety of elements and so on. Therefore, in order to solve the multi-element analysis of single minerals and small amount of samples and to build the tubes of rock and ore
