摘要
氮、氧稳定同位素指标在N2 O源汇识别、全球源汇质量估算中具有独特的定量作用。本文主要讨论N2 O的氮、氧稳定同位素真空制样系统的基本原理、总体设计和技术难点 ,为建立N2 O氮、氧稳定同位素真空制样系统提供理论基础。
Nitrogen and oxygen isotope ratios have given a valuable insight into the mechanisms of N\-2O produciotn, transport and emission, hence providing budgetary information on this important trace gas. This paper discusses mainly the fundamentals, overall procedure and technical difficulties of developing an integrate set of vacuum apparatuses for the analysis of δ\{\}\+\{15\}N, δ\{\}\+\{18\}O and δ\{\}\+\{17\}O of N\-2O.
