您要查找的是不是：
- 87Sr／86Sr87Sr/86Sr ratios
- 平面上由西向東北方向87Sr/86Sr比值增大,說(shuō)明石炭紀海侵是由西向東侵入的。While from west to northeast the average values of 87 Sr / 86 Sr are increasing in plane,indi cating that the marine transgression during the Carboniferous period happened in direction from west toward east.
- 塔里木盆地塔中地區上奧陶統部分海相碳酸鹽87Sr/86Sr比值的降低可能與深部流體的影響有關(guān);The lowering of ()~(87)Sr/()~(86)Sr ratio of the Upper Ordovician marine carbonate may have a relation to the influence of the mantle source fluid.
- 說(shuō)明87Sr/86Sr值能反映地下水的形成、徑流和混合作用,是較理想的示蹤劑,在巖溶水研究中具有很廣闊的應用前景。Therefore, the 87Sr/86Sr ratio can reflect the formation, runoff and mixing of underground water and hence is an ideal tracer with a wide application vista in karst water research.
- 氯化鍶[87Sr]strontium[87Sr]chloirde<放射性藥品>
- 該假說(shuō)把新生代以來(lái)發(fā)生的幾個(gè)主要現象 ,即全球氣候總體上趨冷 ,大氣 CO2 濃度下降 ,海洋 87Sr/ 86Sr比值上升 ,以及構造作用引起的大面積隆升等加以有機的聯(lián)系 ,給以了合理的解釋。The main events since the Cenozoic include: (1) cooling of the global climate; (2) decrease of concentration of the atmospheric CO 2; (3) ascent of the marine 87 Sr/ 86 Sr, and (4) lift of a large areas driven by tectonics.
