"The potassic and sodic mantle alkali-rich magma systems" are the integral of all ig-neous rocks that are formed in a short geological period, and include the ultrabasic, basic, inter-mediate and acidic alkali-rich rocks along deep faults.

钾质富碱岩浆岩组成的岩带研究表明，这类岩石普遍富碱和CaO，高钾，富Rb，Sr，Ba和放射性元素Th，U等，Rb/Sr相对较低；稀土元素总量较高，强烈富轻稀土，δEu较小；I_多数介于0。

In this study, EPMA and LA-ICP-MS were used to determine the major and trace element concentrations, respectively, of apatites from Transhimalayan granitoids. The results indicate that F, Mn, Sr and REEs in apatites generally show good correlations with compositions of their host magmas and thus have high potential to be utilized as petrogenetic tracers. More specifically, F and Mn contents in apatites are covariant with the aluminosity of the host rocks so that can be used as an indicator for magma differentiation. Combining with Sr and REE data, which show significant variations in apatites from different rock types, these elements may be furthermore used to construct "discrimination diagrams" for more detailed investigations of complex petrogenetic processes such as magma mixing and compositional heterogeneity.

本研究中，电子微探以及雷射烧蚀感应耦合电浆质谱术分别被用以量测藏南火成岩中磷灰石的主量与微量元素含量，微区分析的结果显示，磷灰石的氟、锰、锶以及稀土元素均与岩浆源成分展现良好的对比关系，揭示了它们应用在岩石成因示踪上的优秀潜力：其中，磷灰石氟、锰含量的变化与原岩的铝饱和情形息息相关，因此可以作为岩浆分异程度的指标；而锶以及稀土元素则在不同岩石类型来源的磷灰石中展现了明显的丰度变化，因此综合这些元素将有机会进一步建立岩浆来源的「鉴别图」，甚而以此讨论岩石成因，例如：岩浆混合与源区组成的不均一性。

In the present study, we examine a cell line in which we overexpress the SR-BI protein to determine if morphological, biochemical and functional events associated with SR-BI in a controlled cell system are similar to those observed in the intact mammalian adrenal which is responsive to systemic factors.

在当前学习、我们在研究一种细胞过度表达我们的简碧蛋白质确定形态、生化及功能活动与简碧在控制细胞类似于观测系统的完整哺乳动物肾上腺是顺应全身因素。

Some spore-pollen assemblages of late Trias and the youngest zircon of 225Ma were also obtained in this type.Deriveration of the ore is from the upper crust according to the features of trace elements,zircorn U-Pb age and initial value of ~(87)Sr/~(86)Sr.It has not any charateristics of the mantle.

底辟-侵位角砾岩是本次工作新发现的，它在空间上与构造-膏溶角砾岩密切伴生，剖面上呈脉状或火焰状分布，局部呈脉状穿刺于围岩中，其胶结物中含有晚三叠世的孢粉组合，最年青锆石的年龄为225Ma，角砾岩本身是铅和锌的富矿体。

The high BVP percentage reported in the AF group is even more astonishing considering the low use of chronotropic-negative drugs and the lack of use of a ventricular rate regularisation feature, extremely important to ensure biventricular capture in cases of fast irregular rhythm.

在Khadjooi的研究中，在包括阵发性房颤患者的AF的群体中引入了2个重要的偏倚：阵发性房颤患者两心室同步率要高于永久性房颤患者。（AF患者的BVP比例为87%）；阵发性房颤患者的&临床&行为如SR患者。在AF患者群中，接受CRT的正性效果与SR人群相比要差。
