摘要: 激光共振电离谱学和飞行时间质谱学相结合形成的RIS-TOFMS技术是当今超痕量探测技术中最新的、最灵敏的,也是通用性最好的一种.首先简短地介绍一下有关RIS-TOFMS方法的基本原理和它在一些高科技领域中应用的现状.然后,着重论述RIS-TOFMS方法应用于地质科学中勘查地下隐伏贵金属(黄金、铂、…)矿床的设想,并介绍了该实验室有关这方面研究工作的进展情况.从几年来此项工作进展和取得的成果来看,这项研究成果成熟化之后,应用开发的前景是明朗的.亦即,它将是:
(1)发展为陆地深部稀贵金属、稀土金属矿产资源勘探的新型的仪器设备;
(2)发展成为船载的新型的海洋矿产资源勘查的有效的仪器设备;
(3)发展成为材料科学(包括超导体科学)、薄膜科学、环境科学、生物、医学等方面的高科技研究的手段.

Abstract: A combination of Resonance lonization Spectroscopy and Time-of-Flight Mass Spectroscopy (RIS-TOFMS) is the newest and most sensitive method in modern ultra-trace detection. This paper first presents a short account ef the basic principles of RIS-TOFMS and its current applications. Then the application of RIS-TOFMS to geological prospecting of underground concealed ores of precious metals is discussed in detail, followed by a description of the progress of our laboratory work.
From the achievement and development of our work in recent years, we believe its prospect of practical development is bright. It will
(1) Develop new instrument and equipment f or prospecting and surveying underground concealed ores of rare and noble metals and rare-earth metals;
(2) Develop effective ship-born instrument and equipment for prospecting undersea mineral deposits;
(3) Develop into a high-tech research method in materials science (including super-conduction), thin film science, environmental science, biology, medicine, etc.
