Crystalline β-BBO thin films were successfully prepared on (001)-oriented Sr 2+-doped α-BBO substrates by using liquid phase epitaxy, pulsed laser deposition and vapor transport equilibration techniques. The films were characterized by X-ray diffraction and X-ray rocking curve. The present results manifest that the β-BBO thin films grown on Sr 2+-doped α-BBO substrates have larger degree of orientation f value and smaller X-ray rocking curve FWHM than the ones grown on other reported substrates.

采用液相外延法、脉冲激光沉积法以及气相传输平衡法在Sr 2+：α-BBO(001)衬底上生长了质量优异的β-BBO 薄膜，对薄膜进行了X射线衍射测试以及双晶摇摆曲线分析，结果表明，采用Sr 2+：α-BBO单晶作为衬底制备的β-BBO薄膜具有高的择优取向度和低的半峰宽值。

However, the difference between Hongge and Xinjie is also apparent, perhaps reflecting the source difference in the mantle. Relative to the Hongge intrusion the Xinjie intrusion is more depleted in Nd isotope ratio and enriched in REE and LILE. The Xinjie intrusion plots in the first quadrant in Sr-Nd diagram, which shows the Sr isotope-enriched and Nd isotope-depleted slightly feature. This indicates that the source of the Xinjie intrusion may had the mantle wedge signature.

但红格、新街岩体的源区又有所不同，新街岩体较红格岩体Nd同位素更亏损，稀土和大离子亲石元素更富集；新街岩体在Sr-Nd相关图上，位于第一象限，显示Sr同位素富集，Nd同位素略亏损特征，指示了新街岩体的源区可能有残留地幔楔的成分。

An apparent negative excursion at bed 22 is correlated with the globaltemperature decline. The ~(87)Sr/~(86)Sr ratio of 0.707605 can be related to the tectonic processand sea level rising resulting from the rapid Indian Ocean ridge expansion in Campanian.Decrease of detrital weathering materials is resulted from ingression.

在第22层位上，锶同位素曲线出现一处明显的负偏波谷，~(87)Sr/~(86)Sr比值达到了0.707605，此时全球温度也出现下降，对应坎潘期印度洋脊南北向迅速扩张，全球海平面上升，大规模海泛导致盆地中陆地剥蚀物减少。

The same set of ductile-rheologic shear deformational augen granite samples in the Yunkai uplifted area are measured by whole-rock Sm-Nd, Rb-Sr isotopic dating system method, obtaining respectively 1414±68Ma for Sm-Nd isochron age and 490±36Ma for Rb-Sr isochron age. These ages are respectively interpreted as the time of the granitic rock formation and the time of the tectono-thermal event of ductile-rheologic shear partial melting in Caledonian, indicating that the orogeny not only took place in Caledonian, but also the more important tectono-magmatic orogeny in the late Mesoproterozic Era and can be compared with the time of global Grenville orogeny.

对云开核部韧性-流变剪切变形眼球状花岗岩石样品进行了全岩Sm-Nd、Rb-Sr同位素年龄测定，获得1414±68Ma的Sm-Nd等时线和490±36Ma的Rb-Sr等时线年龄，它们分别代表这套花岗岩的形成时代和加里东期韧性-流变剪切部分熔融构造热事件发生时间，表明云开地区不仅在加里东期发生造山运动，而且在中元古晚期发生了更为重要的构造—岩浆造山运动，其时代与全球性的格林威尔造山运动时间可以对比。

Low magnetic susceptibility, low CaCO3, low organic carbon concentration, low C/A (Chenopodiaceae/Artemisia) ratio, low Sr concentration and, hence, high Rb/Sr ratio in the lake sediments indicate a cold but moist climate during the global Little Ice Age in the Daihai area.

在明确湖泊沉积物Rb/Sr比值古气候指示意义的基础上，通过AMS-14C和210Pb精确定年及12.08米岱海沉积岩心的Rb/Sr比值、碳酸盐含量和有机碳含量的变化，恢复了包括中世纪暖期、小冰期及全新世适宜期等典型气候事件在内的全新世环境演化过程，基本认识是：全新世早—中期9-3.5kaB.P。

This heat treatment can prevent the formation of large Sr-Ca-Cu-O particles which can form in tape during isothermic heat treatment of high temperature and can release 30〓 phase in the tape.

发现在银套Bi-Pb-Sr-Ca-Cu-O预烧粉末轧制带热处理中37〓相晶粒以（001）晶面平行带面生成；等温高温处理产生含粗大Sr-Ca-Cu-O相颗粒的组织；升温处理可以避免形成Sr-Ca-Cu-O粗粒并消除30〓相。

The monthly variations in Sr/Ca ratio of the Porites coral from Eastern Hainan Island have been studied using the ICP-AES technique.On the basis of the correlation analysis between Sr/Ca values and SST values measured from the Meteorological Station,a thermometer has been set up as a formula of SST=170-16,n=133,r=0.80,p=0.01,which is similar to the formula of SST=169-16.7 for Xisha waters.

文章采用全谱直读等离子体原子发射光谱的方法测定了1986~1996年海南岛东部海域滨珊瑚的Sr/Ca比值，建立了该海域月分辨率的Sr/Ca海水表面温度计方程：SST=170-16，n=133，r=0.80，p=0.01，此与韦刚健等在西沙海域建立的温度计方程：SST=169-16.7一致，这表明南海中、北部海域也出现有相似的微量元素温度计。

In addition,the bitumen layer, such as Dingying and Mingxinsi formation should be given priority as potential source rocks. The organic type is Sapropel type. According to the trace element and the analysis in Sr/Ba, V/Ni, Sr/Ca, Ca/Mg, Th/U, it's proved that the sedimentary environment is marine.

通过对微量元素的分析，对Sr/Ba、V/Ni、Sr/Ca、Ca/Mg、Th/U进行了对比，证实了研究区当时的沉积环境主要为海相沉积环境，同时该区海水盐度逐渐降低，属海退系列沉积。

In reconstructed LV during SR/RVP,multiple scars with one or more isthmuses were presented on the reconstruction of the LV.RF current was delivered during hemodynamically unstable VT in 4 pts and abolished all VTs,in other 8 pts RF current was delivered only SR/RVP pacing due to very unstable hemodynamic status or mechanic in jury.
