gas isotope ratio mass spectrometer meaning in English

气体同位素比质谱计

To let more domestic relevant researchers understand the applicable techniques of stable isotopes , this article not only introduces the principles of isotopes measurements by gas isotope ratio mass spectrometer , but also integrates the experiences of hydrogen , oxygen , carbon , nitrogen , and sulfur isotopes in agriculture and environmental applications that were described in papers
为让国内更多相关研究人员了解稳定同位素技术的可利用性，本文描述气相同位素比值质谱仪之分析原理，及整理氢、氧、碳、氮和硫等同位素在农业及相关生态环境研究上应用的文献。
The understanding of biogeochemical cycle of hydrogen , oxygen , carbon , nitrogen , and sulfur elements in nature ecosystem have increased substantially in the past two decades owing to the improvement of gas isotope ratio mass spectrometer and the wide application of isotopic studies with these elements
摘要近20年由于气相同位素比值质谱仪的改良和氢、氧、碳、氮和硫等稳定同位素的广泛研究，稳定同位素的研究技术已实质增加我们对于这些元素在自然生态系中生地化循环的了解。
