Based on the petrological and geochronological study of metamorphic complexes from the Grove Mountains, the following conclusions are reached.(1)Exsolution texture is widely found in clinopyroxene in mafic granulites. A peak metamorphic temperature of 850 C was obtained from the reintegrated compositions of exsolved clinopyroxene. The preservation of augite megacrysts suggests a single episode of high-grade metamorphism for the Grove Mountains.(2)The compositional comparison of garnet from pegmatites with that from country rocks demonstrates that garnet in pegmatites is of xenocryst origin, and late amphibolite facies metamorphism does not occur in this area.(3)The Pan-African charnockite and post-tectonic sheet-like granite were first recognized in East Antarctica. Their occurrences suggest a collisional orogeny during the Pan-African time.(4)The SHRIMP U-Pb zircon dating on various rock types indicates that the major metamorphism in the Grove Mountains occurs at c. 550 Ma, and the tectonothermal evolution terminated at c. 500 Ma. The Grenvillian granulite facies metamorphism did not develop in the studied area.(5)The Prydz belt, the second Pan-African suture within the Gondwana suppercontinent, was further comfirmed based on this study. The Gondwana suppercontinent was not formed by the simply juxtaposition of East and West Gondwana, but by the collision of several blocks during the Pan-African time.
本项目通过格罗夫山地区高级变质杂岩的变质岩石学和同位素年代学研究,获得如下重要认识:(1)发现辉石出溶结构,由此获得峰期变质温度为850 C,并根据火成普通辉石的识别确定该区只存在单相麻粒岩相变质;(2)通过伟晶岩中石榴石斑晶与围岩中石榴石的对比研究提出了石榴石的捕虏晶成因,进而确定该区不存在晚期角闪岩相变质作用;(3)在东南极首次识别出泛非期紫苏花岗岩和后构造层状花岗岩,为泛非构造热事件的碰撞造山成因提供了重要佐证;(4)对不同岩石类型的锆石SHRIMP定年精确地限定了格罗夫山地区主期变质作用发生于泛非期,~550 Ma,热事件结束于~500 Ma,年代学数据没有揭示在该区存在格林威尔期麻粒岩相变质作用的迹象;(5)进一步确认了东南极内部普里兹带的存在,它属于冈瓦纳超大陆内部的第二条泛非期缝合带,据此认为冈瓦纳超大陆并不是由东、西冈瓦纳陆块的简单拼合而成,而是多个不同块体拼合的结果。

Her griddlecakes done to a goldenbrown hue and queen Ann's pudding of delightful creaminess had won golden opinions from all because she had a lucky hand also for lighting a fire, dredge in the fine selfraising flour and always stir in the same direction, then cream the milk and sugar and whisk well the white of eggs though she didn't like the eating part when there were any people that made her shy and often she wondered why you couldn't eat something poetical like violets or roses and they would have a beautifully appointed drawingroom with pictures and engravings and the photograph of grandpapa Giltrap's lovely dog Garryowen that almost talked it was so human and chintz covers for the chairs and that silver toastrack in Clery's summer jumble sales like they have in rich houses.
她那烤成金褐色的薄饼和放有大量美味奶油的安妮女王布丁曾赢得过众人的好评。因为她有一双灵巧的手,不论点火,还是撒上一层加了发酵粉的精白面,不断地朝一个方向搅和,然后搀上牛奶白糖,调成奶油,或是将蛋清搅匀,她样样擅长。不过,她可不喜欢当着人面吃什么,怪害臊的。她常常纳闷为什么不能吃一些像紫罗兰或玫瑰花那样富于诗情的东西!他们还会有一间布置优雅的客厅,装饰着绘画、雕刻以及外祖父吉尔特拉普那只可爱的狗加里欧文的照片。它是那样通人性,几乎能说话了。椅子套着光滑的印花棉布罩子,还有来自克莱利的夏季旧杂货义卖展上的银质烤面包架,就像阔人家拥有的那样。

Huangqiao carbon dioxide gas field in North Jiangsu Basin have the following characteristics: deep gas fields are associated with shallow ones, marine gas fields are coupled with continental ones, and several gas reservoirs are combined. Carbon dioxide in Huangqiao area mainly comes from deep mantle, mixed with a little thermal metamorphism and a little organic carbon dioxide in shallow formation, and helium and nitrogen gas mainly come from mantle. There is a good time\|space matching relationship between carbon dioxide gas reservoirs and great rifts, magma and volcano activity, which forms the special carbon dioxide gas reservoir mode for Huangqiao. This mode has good sealing, trapping and preserving conditions, but its gas source differs from traditional hydrocarbon gas reservoirs.

The humidity resistance and the sensitivity to chemical warfare agents simulants of the tuned films were also investigated.Self-assembled LBL polyaniline films were prepared from aniline monomers by in situ polymerization and the mechanism of film formation was discussed. It was proposed that the self-assembly of polyaniline occurred through the quick absorption of aniline monomer cations or aniline monomer cation radicals on the glass surfaces by electrostatic attractions to form homogeneous polymerization centers, then increased gradually by the way of upright to the glass supports for extensity, leading to the polyaniline chain growth. The polyaniline was doped under acidic condition to absorb anionic polyelectrolyte, such as sodium polystyrene sulfonate based on the electrostatic force, or to adsorb polymer based on hydrogen-bonding interactions, for example Polyvinyl Alcohol, and then recycled to fabricate_n or_n self-assembled multilayer films.

Therefore, the EL spectra of (Znq_2)_4 is wider than that of Znq_2. 4._2 was synthesized. The analysis of molecular spatial structure and the characterization of material performance of_2 and Liq showed that two Liq molecules and two Naq molecules were connected by Na-O-Na bond bridges to form_2. Compared with Liq,_2 exhibits stronger rigidity in planar molecular structure, larger steric hindrance and intermolecular distance, and much smaller molecular polarity, thus resulting in much longer fluorescence lifetime, much higher fluorescence quantum efficiency, wider energy bandgap and better film formability. When used as light-emitting layer in OLED,_2 shows lower formation probability of excited dimmer and exciplex formation than Liq, thus emits bluer light with higher current efficiency than Liq. When_2 ultrathin film is used as electron injection layer in OLED, it exhibits higher current density, higher luminance, lower turn-on voltage and higher current efficiency than Liq ultrathin film for the existence of sodium ions in_2 ultrathin film. 5. The summarization the relationship between molecular spatial structure and material performance of Alq_3,(Znq_2) and Liq, lead the conclusion that the molecular spatial structure of Mq_n affects its material performance in such aspects as the rigidity of planar molecular structure, intermolecular interaction, molecule stacking mode and intermolecular distance.
