The influence of Ce, Nd and Sr on the as-cast microstructure of AZ91 alloy was investigated by optical microscope、scanning electron microscope、electron probe microscope analyzer、differential thermal analyzer and X-ray diffract analyzer, et al.

本文以目前使用最广泛的AZ91镁合金为研究对象，分别添加不同含量的稀土元素Ce、Nd和碱土元素Sr，研究了三种元素对AZ91镁合金微观组织和腐蚀性能的影响。

The ε sr of eclogite in the Dabie UHPM zone varies from 18 to 42,and ε Nd from -6.1 to -17,showing remarkable isotopic disequilibrium.

大别山榴辉岩的εNd为-6.2～-17，εSr为18～42，且显示明显的Nd同位素的不平衡现象。

In order to study the source of ore-forming materials and genesis of fluorite deposit, Sr isotopic composition was studied.

为了研究成矿物质来源及矿床成因，对该矿床进行了Sr同位素研究。

The distributive characteristics of Sr, Sc, K and REE such as Ce, Y are consist with Ca to some degree. Which means those elements host in Ca〓 sites of francolite. Certainly, other sites of these elements are still exist. It is sug gested that the change of mieroenvironment is the cause of the variation of Mn.

Sr、Sc、K及稀土元素Ce、Y在结核内的分布形式在一定程度上与Ca的位置，当然，它们还有其它赋存形式，Mn的变化可说明了磷结核形成作用过程中微环境发生了一定的变化。

From PG8 MCA Report, they select Standard Gauge block P/N SR－90, S/N 0005. So for your PWP and FWP. And if we have another standard gauge block for test not use 1.1mm thickness coupon as standard?Thx!

从INTEL 马来PG8工厂MCA文件，他们选用标准量块P/N SR－90， S/N 0005，所以对你的INTEL技术官方文件PWP和FWP，是否我们需要其他标准量块而不是用1.1MM的作为标准？

Whole-rock Rb-Sr isochron age of 114Ma in Yanbei granite porphyry and single grained zircon U-Pb age of 138Ma in Tashan granite porphyry indicate that these two tin-bearing porphyry both are the products of Late Yenshan magmatic activity.

岩背花岗斑岩的全岩 Rb-Sr 等时线年龄（114Ma）和塌山花岗斑岩颗粒锆岩 U-Pb 年龄（138Ma）表明，这两个含锡花岗斑岩都是燕山晚期岩浆活动的产物。

However, there are considerable differences in their initial Sr and oxygen isotope compositions, indicating that the monzogranite was not derived from the granodiorite.

然而二者的初始Sr同位素组成存在一定的差异，表明二长花岗岩并非是花岗闪长岩分异作用的产物。

It yields an Rb-Sr isochron age of 174.4Ma Ma (2σ), which is in accordance with their host granodiorite dated as 173.3±2.9 Ma by single-grained zircon U-Pb method.

黄铁矿Rb-Sr等时线年龄与花岗闪长岩体的单颗粒锆石U-Pb年龄十分一致，表明矿床的形成与岩体有密切的联系，花岗闪长岩体提供了矿床形成所需要的能量和部分流体，而地层也提供了部分成矿物质。

Dietary guaiacol significantly (P＜0.05) decreased contents of Ca and Sr, but significantly increased Mg content in shell.

愈创木酚显著降低贝壳中Ca和Sr的含量，然而显著升高贝壳中Mg的含量（P＜0.05）。贝壳中P和Zn的含量不受愈创木酚的显著影响。
