同位素值 meaning in English
isotope value
Examples
- Thus , comparing two aspects n - alkane of longer and shorter train mentioned above , it could be better to estimate the change of the altitude and the environment during the past time
另一方面，检验了过去人们对于长链烷烃的认识，随着海拔的升高，长链烷烃单体烃碳同位素值变小。这两方面的对比可以更好地预测海拔变化和环境变化。 - Author pay more attention to the carbon isotope values of gas in fluid inclusions . the methods of pyrolysis and vaccum ball grinding have been used to obtain carbon dioxide , methane and other gases . then , the carbon isotope values of these gases have been identified by gc - c - ir - ms
加强了对包裹体中气体碳同位素测定方法研究，真空球磨法提取气体进行碳同位素分析的方法无裂解和氧化反应，代表真实流体，测定的碳同位素值可靠。 - This paper researches on the water and suspension in zhujiang ( pearl ) river and her three branches , sampling in makou hydrological gorge station of xijiang river , hekou hydrological gorge station of beijiang river and boluo hydrological gorge station of dongjiang river . the author calculated the riverine carbon flux and measured the content of different carbon forms and carbon isotope composition . furthermore , the author also studied drainage basin erosion and the influence of vegetation distribution on erosion
本文以珠江水体、悬浮物为研究对象，通过对西江马口、北江河口、东江博罗断面水体取样，分析水体中不同形态碳含量，测定碳同位素值，并计算了河流碳通量值；还对珠江流域的侵蚀状况及植被分布对流域侵蚀的影响进行了探讨。 - Although samples were in a hot reflux for a long time at 85 in the experiment , and 5 ? molecular sieve of the adsorbed sample was acidized by hydrofluoric acid , the analytical method was tested to have little influence on carbon isotopic composition of the saturated hydrocarbons before and after complexation
尽管实验过程中样品经过85长时间加热回流及吸附样品的5 ?分子筛用氢氟酸酸化处理，但实验结果经仪器检测，证明该方法对正构烷烃碳同位素值影响因素不大。
