spectro analysis of isotopes
4.THG APPLICATION OF STABLE ISOTOPES TO THE PROSPECTING EVALUATION OF GOLD ORE DEPOSITS
5.APPLICATIONS OF NATURAL ISOTOPES OF ~7Be AND ~(210) Pb IN ATMOSPHERIC SCIENCE
6.STUDIES ON SEPARATION OF LITHIUM ISOTOPES BY SOLVENT EXTRACTION——Ⅰ.THE SEPARATION EFFECTS OF LITHIUM ISOTOPES BY SUDAN I-NEUTRAL LIGAND SYNERGETIC EXTRACTION SYSTEMS
8.Using new developed radiochemical analysis methodsand instruments, and collecting the surface soil samples from variousareas of Japan, sectiments on the bottom of lake and sea,sea waterand those samples related to the Bikini event happened in. 1954.The content of plutonium isotopes,~(241)Am and ~(237)Np in environmentalsample,their depth profile variation with time and the-relationshipbetween them with organic materials were studied.
9.ENRICHMENT OF LITHIUM ISOTOPES BY HIGH PRESSURE ION EXCHANGE DISPLACEMENT CHROMATOGRAPHY (Ⅲ)--SEMICONTINUOUS ENRICHMENT
10.The enrichment and analysis method of trace organic matter in formation water are briefly introduced in this article. Making use of the geochemical data of saturated and aromatic hydrocarbons from 9 water samples (including 8 drilling well formation water and 1 fountain water ), combined with the general analysis on formation water (abiochemistry and isotopes of δDδ~(18)O), we discuss the different conservation condition in the two areas.
