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。

I flipped open my blanket, and there lies the source of the 'problem'... a broken bowl with instant noodles and a mess on the bed sheet and blanket!Boy, was I mad! I was so furious that I took a clothes hanger, charged straight at my child who was happily playing with his toy, and give him a good spanking!

Article 8 : At the start, each rider will receive a brevet card and a cue sheet indicating the route and the location of the checkpoints. Riders must stay on the route. If a rider leaves the route, they must return to the route at the same point prior to continuing, ie. no shortcuts or detours from the route, unless specified by the organizer. Riders must stop at each checkpoint to have their card stamped.

The Orion was a ship that had been ailing for a long time; in the course of its previous cruises thick layers of barnacles had collected on its keel to such a degree as to deprive it of half its speed; it had gone into the dry dock the year before this, in order to have the barnacles scraped off, then it had put to sea again; but this cleaning had affected the bolts of the keel: in the neighborhood of the Balearic Isles the sides had been strained and had opened; and, as the plating in those days was not of sheet iron, the vessel had sprung a leak.
俄里翁号是一条早已有了毛病的船。在它已往的历次航行中,船底上已结聚了层层的介壳,以致它航行的速度降低了一半,去年又曾把它拖出水面,剔除介壳,随后又下海了。但是那次的剔除工作损伤了船底的螺栓。它走到巴利阿里群岛时,船身不得劲,开了裂,由于当时的舱座还没有用铁皮铺底,那条船便进了些水。

By the combination of experimental results with theory of crystal growth, some growth models and growth mechanisms were proposed. Research results confirmed that pillar-shaped TaC whisker with spherical droplet at the end grew via a vapor-liquid-solid mechanism, pillar-shaped whisker with pyramid-like end was formed via a vapor-solid mechanism, awl-shaped TaC whisker with zigzag end formed via a liquid-solid mechanism, awl-shaped TaC whisker with growth step at the end has a growth mechanism of screw dislocation mechanism. The growth mechanism of dumbbell-shaped MgO nanowhisker and NaCl particle-decorated MgO nanowhisker is VS; C and MgO powder-yielded MgO nanowhisker was formed via a VLS mechanism, Mg powder-yielded MgO microwhisker and MgO microsized or nanosized crystal sheet grew via a VS mechanism. In the Si and SiO〓 nanostructures, Si nanowires formed in higher-temperature zone grew via oxide-assistant mechanism, while Si nanowires or nanorods formed in lower-temperature zone have a growth mechanism of VLS, and the growth mechanism of SiO〓 nanowires is VS.

But our patron, warned by this disaster, resolved to take more careof himself for the future; and having lying by him the longboat ofour English ship that he had taken, he resolved he would not go a-fishing any more without a compass and some provision; so heordered the carpenter of his ship, who also was an English slave,to build a little state-room, or cabin, in the middle of the long-boat, like that of a barge, with a place to stand behind it tosteer, and haul home the main-sheet; the room before for a hand ortwo to stand and work the sails.
但是,我已被摩尔人吓破了胆,生怕再落到他们的手里;同时风势又顺,于是也不靠岸,也不下锚,一口气竟走了五天。这时风势渐渐转为南风,我估计即使他们派船来追我。这时也该罢休了。于是我就大胆驶向海岸,在一条小河的河口下了锚。我不知道这儿是什么地方,在什么纬度,什么国家,什么民族,什么河流。四周看不到一个人,我也不希望看到任何人。我现在所需要的只是淡水。我们在傍晚驶进了小河口,决定一等天黑就游到岸上去,摸一下岸上的情况。但一到天黑,我们就听到各种野兽狂吠咆哮,怒吼呼啸,不知道那是些什么野兽,真是可怕极了!这可把那可怜的孩子吓得魂飞魄散,哀求我等天亮后再上岸。我说,&好吧,佐立,我不去就是了。不过,说不定白天会碰见人。他们对我们也许像狮子一样凶呢!&佐立笑着说,&那我们就开枪把他们打跑!&佐立在我们奴隶中能用英语交谈,虽然发音不太地道。
