1) same-point ratio
同点比值
1.
Using same-point ratio method in magneto-electric prospecting, a better prospecting effect can be gain.
自然条件下的异常地质体常具有近于圆柱状体的形状 ,而且其走向长度通常为有限值 ,因此 ,当采用磁电勘探中的同点比值法进行勘查时可以收到较好的勘探效果。
2) Isotope ratios
同位素比值
1.
In recent years,with the improvement of sensitivity and resolution,its application was increasing to determine radionuclides content and isotope ratios.
近年来,随着检测灵敏度和分辨率的提高,该技术在放射性核素含量和同位素比值测定中的应用日益突出。
4) isotopic ratio
同位素比值
1.
The results show the isotopic ratio for 143Nd/ 144Nd is 0.
采用 VG Axiom型多接收双聚焦等离子质谱仪 ( MC-ICPMS)测定 Nd、Pb、U同位素比值 ,应用指数公式对测定的结果进行质量歧视校正。
5) percents of the average flow in the same periods
同期均值比
1.
On the basis of two different understandings to the Tennant method,there are two approaches to setting ecological flow:one using the percent of the average annual flow and the other using the percents of the average flow in the same periods(the whole year being divided into several periods).
但是,对于保护河流生命健康与维持生物多样性来说,Tennant法存在着某些不合理之处;在具体应用中又有年均值比和同期均值比之别。
6) lead isotope ratios
铅同位素比值
1.
Lead isotope ratios of tea soil from different regions in Fujian Province were determined by inductively coupled plasma mass spectrometry, the differences of lead isotope ratios (206Pb/207Pb-206Pb/208Pb).
本研究利用电感耦合等离子体质谱测定了福建不同茶园土壤的铅同位素比值,比较了土壤全消解和残渣态两种赋存形态的铅同位素比值的差异,发现残渣态的铅的地域性特征较强,可用来作为地区土壤的判别依据。
2.
Based on the analytical method, lead isotope ratios of Danshen could be accurately measured.
建立了用微柱流动注射与电感耦合等离子体质谱联用的铅同位素比值测量方法。
