城乡建设环境保护部综合勘察院为配合城市水资源、地下热储和环境质量与影响评价、开展了环境同位素水文地球化学研究,并于一九八四年建立了氢氧稳定同位素实验室。到目前为止,已作了三百多次分析。初步完成利用CO_2平衡法分析天然水中氧同位素组成(δ~(18)O)的条件试验,分析精度(σ=±0.07‰),完全达到一般要求,并建立起实验室氧同位素分析工作标准(8401无菌注射用水),同时还分析了北
Urban and Rural Construction Department of Comprehensive Investigation of Environmental Protection Department To carry out environmental isotope hydrogeochemistry research in line with urban water resources, underground thermal storage and environmental quality and impact assessment, and in 1984 established the hydrogen and oxygen stable isotope laboratory. So far, more than 300 analyzes have been made. The conditions for the analysis of oxygen isotope composition (δ ~ (18) O) in natural water by CO_2 equilibrium method are basically completed. The analytical precision (σ = ± 0.07 ‰) meets the general requirements and establishes the working standard of laboratory oxygen isotope analysis 8401 sterile water for injection), while also analyzing the North
