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。

The course will start with an overview of the central and peripheral nervous systems, the development of their structure and major divisions. The major functional components of the CNS will then be reviewed individually. Topography, functional distribution of nerve cell bodies, ascending and descending tracts in the spinal cord. Brainstem organization and functional components, including cranial nerve nuclei, ascending / descending pathways, amine-containing cells, structure and information flow in the cerebellar and vestibular systems. Distribution of the cranial nerves, resolution of their skeletal and branchial arch components. Functional divisions of the Diencephalon and Telencephalon. The course will then continue with how these various CNS pieces and parts work together.

Due to the difference of the terrain and rainfull between Taiwan and the other countries, the fishway of the check dam in Taiwan can not be completely imitated from other country. Therefore Slopeland Engineering Lab of Department of Soil and Water Conservation , NCHU makes a series of experiment in fishway of the check dam from 1998-2008. The experiments focus on structure of inclined section、horizontal section and U-turn horizontal section of the fishway.

The technique of CAE about injection molding is based on polymer processing rheology and conductive calorifics. It simulates the actual process of melt filling, packing and cooling by setting up mathematic and physical models about melt flowing and heat transmitting in the mold cavity, and working out the results by the theory of numerical value analysis. It can also list the processing parameters quantificationally such as pressure, time, temperature, speed, etc, and reflect the results visually by computer figures.

And tell you the principle concerning bike,we can learn how and when it was invented and its basic structure as well from the passage.we got the history of bike and when it become popular,these are really interesting.although we usually ride bike around,we're not familiar with the history and the basic structure of it.after learning the unit,it give me a fresh knowledge of bike,and also tell us commonsensibles like how to forbit downdipping while riding in muddinesses and so on.it's a great help for us.because why don't learn more to keep our bikes more safe?
而且从文章告诉我们自行车是怎么样发明的?什么时候发明的?它的构造又是怎么样的?让我们了解了自行车的历史。以及它是什么时候开始流行的。这些都相当有意思。虽然平时我们经常骑脚踏车,可对他的历史来源和它的简单构造也不是很清楚,但学了这单元之后,使我对脚踏车又有了一个新的认识。而且它还告诉我们,当我们骑在泥泞的地面时,怎么样避免下沉?等等一些常识性的问题,可以让我们在现实生活中运用到,这是起着很大作用的,因为多点了解就能让自己的行车得到更好的安全保证。何乐而不为呢?
