硝酸盐中氮和氧同位素比值的测定及其地质意义

Progress in Isotopic Measurement of N and O in Nitrates and Their Geological Signficance

本文系统总结了硝酸盐中氮和氧同位素组成的测定方法及其地质意义研究现状。基于此，作者指出硝酸盐中氮和氧同位素在地质上的应有前景依赖于两方面：精确灵敏快捷的同位素测定方法及其地质意义的深入开发研究。

This paper systermatically summarizes the present situation of the reseach on theisotopic comsition determination methods of N and O in nitrates and their geological significance. Based on this,the authors point out that the application prospect of N and O isotopesin nitrate depends on two aspects: convenient determination method with high precision andsensitivity and deepgoing investigation of their geological significance.
