Study on Enviromental Fluoride & Contamination by Nuclear Reaction Analysis(NRA) 环境中氟污染的核反应分析(NRA)研究
The results show that for the research of environmental fluoried & contamina-tion the nuclear reaction analysis is very useful. 研究分析的结果表明,核反应分析(NRA)法对环境中氟污染的研究是很有意义的。
Charged particle induced prompt nuclear reaction analysis ( PNR ) can not only analyze the content and concentration of elements in sample sensitively and accurately, but also can measure the distributions of elements with depth in surface and near surface layer. 带电粒子引起的瞬发核反应分析(NRA)(PNR)不仅能灵敏和准确地分析微量元素在样品中的含量和浓度,而且能测量在样品表面层和近表面层中元素随深度的分布。
The distribution and content of hydrogen in DLC films prepared by plasma based pulsed bias deposition were characterized systematically by nuclear reaction analysis ( NRA ). 用核反应分析(NRA)方法,对等离子体基脉冲偏压沉积DLC膜的氢分布和氢含量进行了较系统的研究。
Determination of POTASSIUM-39 in rock samples by using nuclear reaction analysis 用核反应分析(NRA)法测定岩石样品中~(39)K的含量
