Ericson (1985) first proposed strontium isotope ratio in human tooth enamel and bone to identify migration and the geologic origins of immigrants. Since then, the method has been thought highly by many archaeologists.

自从1985年Ericson首次提出利用人类牙釉质和骨骼中的锶同位素比值来研究人类的迁移情况和外来人口的来源地之后，这个方法就受到了考古学家的重视。

The effect of additives on synthesis of xonotlite fiber with nano diameter is studied using industrial lime and quartz powder,selecting calcium chloride,strontium nitrate,zirconium oxychloride as additives.

采用工业石灰和石英粉，选用氯化钙、硝酸锶、氧氯化锆为添加剂，研究添加剂对合成纳米直径硬硅钙石纤维的影响，结果表明，几种添加剂均对生成硬硅钙石纤维有一定的帮助，加入适量的氧氯化锆添加剂，可以制备出纳米直径的硬硅钙石纤维，氧氯化锆的添加量为Zr4+/(Ca2++Si4+)=0.02时，可获得结晶良好、直径为70～100 nm的硬硅钙石纤维。

The measuring principle, design method and configuration of the system are introduced. Then, the measuring system is calibrated by testing Lead Zirconate Titanate ceramic and Lithium Tantalate crystal with the known pyroelectric coefficients as the references. In addition, the pyroelectric coefficients of several common ferroelectric thin films such as PZT, PVDF (poly-vinylidene fluoride) and BST are tested.

介绍了该系统的测量原理、设计方法及组成，用已知热释电系数值的锆钛酸铅陶瓷及钽酸锂单晶作为参考样品对系统进行了调试，并对PZT、聚二氟乙烯及钛酸锶钡等几种常见的铁电薄膜材料的热释电系数进行了测试。

The sensitivity according to Sandell has been increased 4 times higher than that reported by Takagi, with buffer solution of LiOH-H3BO3 to control PH value of the queous phase instead of triethylamine.

详细研究了有关的条件。在既定条件下，大量的锂，至少5倍的钠、钙和镁以及0.5倍的铷、铯、钡和锶不干扰钾的测定。

Kubusunan granite is chracterized by low87Sr/86Sr initial values and high ε values, indicating its origin partly from mantle rocks. The number of microgranular dioritic enclaves is the direct evidence for crust-mantle magma mixing, thus showing that enclaves are the residual formed from the partly fusing of basic magma.

库布苏南花岗闪长岩体具有低锶初始比值I和正ε值，表明花岗岩的来源有地幔物质参与，而大量发育的暗色微粒闪长质包体是壳幔岩浆混合作用最直接的证据，微粒包体是基性源岩部分熔融作用形成的残余体。

The 170 meters deep underground of this area has mineral water that contains rich strontium and metasilicate. The high density of around fruit trees and second growth forests have formed natural oxygen bar in the area, with the air quality keeping class 1 level whole year. It was the only area of Beijing vicinity that was not infected by SARS- seems specially blessed.

P6四季和谐的更迭，繁衍着生机；天赋异禀的矿水床，使地下170米蕴涵着丰富的锶、偏硅酸型天然矿泉水；周围和社区内高密度的果树和次生林带形成了天然的氧吧，空气质量常年一级；因是北京周边唯一没有被非典侵扰的地方而更显灵佑。

In order to determine the metallogenic epoch of the gold- silver deposit s in Zhejiang province, the fluid inclusions in quartz from the Huangshan gold deposit, Zhilingtou gold- silver deposit aad Haoshi silver deposit were dated by the Rb-Sr isochron method.

浙江三种不同类型的金、银矿床(璜山金矿、治岭头金-银矿和毫石银矿)的铅、锶同位素组成有显著的差别，这反映了三个矿床的不同来源和成因。

The SBT thin films with STO seeded layer on MFIS structure also appear prefer (115),(006) orientation and good crystallinity. The seeded layer of STO effectively resists the diffusion of Bi into Ir bottom electrode on MIM structure. The remanent polarization and leakage current density of Sr0.8Bi2.6Ta2O9+x thin films with STO seeded layers are significantly improved. In MFIS structure, the Sr0.8Bi2.6Ta2O9+x thin films with STO seeded layer are improved memory window and lead to lower leakage current at low voltage.

在具有STO晶种层基材上沉积之钽酸锶铋铁电薄膜於700℃淬火后，无论在MIM和MFIS结构上皆可得完美(115)方向之SBT结晶相，而STO的种晶层在MIM结构中确实可以有效的阻止铋原子扩散进入底电极，而降低漏电流，在MFIS结构中虽然得到一较小极化值，但由於铁电层所分配到的电场值反而因介电常数值降低而增加，因而得到较大的记忆窗。

The Sr isotopic growth periodicity is relates to the annual variation of Sr isotope in the surface layer of sea-water.

锶同位素的周期性主要是由于附近大陆年周期性降雨量的变化所引起的，它不受生物生长作用的影响。

However, as the name（read－only memory）implies, CD disks cannot be written onorchanged in any way.

然而，正如其名字所指出的那样，CD盘不能写，也不能用任何方式改变其内容。
