查询词典 SR

The volcanic rocks consist of trachytic basalt, basaltic latite, latite and trachyte. The characteristics of this volcanic sequence are: low TiO2 and silica saturation, high alkalis, high K2O/Na2O value and Fe2O3/FeO value, high and variable Al2O3, enrichment in Rb, Sr, Ba, Zr, U, Th and LREE.

岩石硅近饱和，全碱含量（尤其是K2O）高，K2O／Na2O、Fe2O3／FeO比值大，Al2O3含量高且变化大，TiO2含量低，富集Rb、Sr、Ba、Zr、Th、U和LREE等元素，稀土配分为轻稀土富集型，锶、铅、氧等同位素显示了岩浆的幔源特征。

Recent studies suggest that the Mesozoic granitoids and the contemporary mafic and ultra-mafic rocks from the North China block and Dabie-Sulu orogenic belt have the similar Sr, Nd isotopic characteristics, and many of the granitoids and volcanic rocks exhibit some features of adakites.

近年来的研究证实，华北地台和大别—苏鲁造山带的中生代花岗岩与同时代的镁铁质超镁铁质岩有类似的Sr、Nd同位素特点，许多花岗岩和火山岩还具有类似埃达克岩的地球化学性质。

According the Sr - Nd isotopic and trace element characteristics and field observation, the mafic dikes are not affected by crustal material during emplacement.

The mineralogy, petrology, rare earth and trace element geochemistry, Re-Os and Sr-Nd isotopic geochemistry of the black shales and cherts of Yuretusi Formation at the bottom of the Cambrian in Xiaoerbulake and Shugeitebulake sections from northern Tarim Basin have been systematically studied. It was discovered that the high enrichment of some deep source metal elements in the black shales deals with the activity of hydrothermal fluid from the lower crust or upper mantal.

本项目对塔里木盆地北部肖尔布拉克和苏盖特布拉克两剖面下寒武统底部玉尔吐斯组富有机质黑色页岩和硅质岩的矿物学、岩石学、微量元素、稀土元素、Re-Os和Sr-Nd同位素地球化学进行了系统研究，发现该黑色页岩中部分深源金属元素的高度富集与来自盆地下部上地幔或下地壳的深部物源的热水流体作用有关。

Relationship between Mesozoic granites and mesothermal gold mineralization in Xiaoqinling area has been studied by the typomorphic peculiarities of fluid inclusions and Sr, O and H isotopes of the main types of rocks.

对小秦岭地区与金矿化有关的主要地质体中流体包裹体叠加组合标型特征和有关地质体Sr、H、O同位素组成的标型性研究证明，小秦岭地区中生代中温热液金矿化流体与中生代花岗岩浆分界出的热液之间没有直接联系，成矿流体更可能是一种演化的大气降水。

Using the diffuaion data of La, Sr, the in-fluence of the diffusion of modificator on the incubation period of modificationeffect and critical cooling rate has been discussed.

通过La，Sr扩散数据的比较，分析了变质元素的扩散对变质过程中出现的潜伏期，临界冷却速度等问题的影响。

On the basis of isotope Sr variation, integrated with lithologic association, authigenic mineral assemblage, sedimentary structure and paleontologic evidence, the Shenglihe oil shale is classified into two major sedimentary environments such as tidal flat one and lagoon one.

依据Sr同位素的变化特征，并结合例面的岩性组合特征、自生矿物组合、沉积构造以及古生物标志，将胜利河油页岩划分为潮坪和澙湖两种沉积环境。

FIZZ1 had no effect on the expression of scavenger receptor CD36 in cultured macrophages. FIZZ1 can promote the development of AS by the up-regulation of the expression of SR-A and the phagocytose of fatty substance in VSMCs.

FIZZ1不影响体外培养的巨噬细胞清道夫受体CD36的表达，FIZZ1能促进ox-LDL诱导的体外培养的平滑肌细胞SR-A表达，从而可能加速平滑肌细胞吞噬脂质，促进动脉粥样硬化进展。

Because whole rock samples always contain some retrograde minerals,the tie line of garnet + whole-rock in Sm-Nd isochron diagram or the tie line of phengite + whole- rock in Rb-Sr isochron diagram can give a geologically meaningless age.

由于全岩样品总是含有数量不等的退变质矿物，因此石榴石+全岩 Sm-Nd 法或多硅白云母+全岩 Rh-Sr 法将有可能给出无地质意义的年龄。

Compared to average compositions of shales, minor elements of phos phate concretions show that they contain more Ba, Sr, V, Cu, Zn, Co and REE and less Zr, Se, Ga, B.

磷结核的主要元素组成表明：与页岩的平均值比较，磷结核中富集了Ba、Sr、V。
