用法和例句

The characteristics of radiogenic Sr, Pb and unradiogenic Nd show that the Cenozoic high-K calc-alkaline series volcanic rocks from Zuerkengwula mountain area in Northern Tibetan Plateau have a relatively high value of ~(87)Sr/~(86)Sr, a relatively low value of ~(143)Nd/~(144)Nd and a relatively high Pb isotopic composition.

　通过对藏北祖尔肯乌拉山地区新生代高钾钙碱岩系火山岩Sr,Nd,Pb同位素成分的系统测试分析表明,火山岩具有相对高的87Sr/86Sr和低的143Nd/144Nd值及高的Pb同位素组成特点,且Sr,Nd,Pb同位素比值变化范围很窄,反映了其具有同源岩浆的特点,并且经历了类似的地球化学动力学过程。
