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 combination of corundum-coated cBN abrasive with vitrified bond is better than that of Ti-coated or un-coated cBN. And the buffer layer from cBN abrasive, corundum coating to bond is perfect because part of corundum coating melts into vitrified bond to build dentation combination.

表面涂覆刚玉和镀覆Ti的cBN磨粒与结合剂的结合效果均比未镀覆的好，但涂覆刚玉比镀覆Ti的效果更好，刚玉涂层以牙形溶入结合剂中使得磨粒、镀层和结合剂三者过渡良好。

Feixianguan Formation of lower Triassic is an important reservoir, which mainly consists of the dense oolitic dolomite and limestone altered by the late dolomitization of oolitic bars.

四川盆地东北部的三叠系下统飞仙关组是重要的油气储层，其储集岩体主要为经晚期白云岩化改造的鲕滩坝沉积的致密鲕粒白云岩、鲕粒灰岩。

And with decrease in light intensity,the shape of palisade mesophyllchanged from column into invert pyramid.The higher proportion of granum thylakoid,more granum in one ganum thylakoid and lower ratio of chlorophyll a to chlorophyll bwere also the responses of leaves to shading.

在庇荫环境中，栅栏组织薄壁细胞由全光的柱状变成倒锥形、叶绿素a/b率显著降低、叶绿体中基粒类囊体所占的比例提高、每个基粒类囊体垛的片层数量增加等，也是幼树提高叶片对弱光利用能力的主要标志。

The protective film decreased the surface roughness, and also increaser the friction coefficient in the process BTA absorbed on SiO2 polishing particle surfaces, which decreased the friction coefficient in the polishing process caused by the particles.

另外，BTA对成SiO2抛光磨粒具有一定的吸附作用，进而对抛光效果产生一定的影响，抛光磨粒表面吸附层的存在会减小抛光过程中的摩擦系数。

The introduction of the acrylic or methacrylic acid in middle layer is helpful to obtain a latex with smaller particle size and more narrow particle size distribution.

本文对聚合工艺、乳胶粒中间层分率和软硬单体比例、官能团单体含量等对GAD室温自交联乳液的粒径及分布的影响进行了研究。

In our experiment, the GADes gene from rat brain was cloned and expressed in E.coli, so as to make the recombinant GADes produced by gene technology for clinical application and further study on the relation between GAD and type 1 diabetes mellitus.Firstly, with the pUClS/GADes recombinant plasmid as template, the full-length encoding sequence of GADes was amplified by PCR, and cloned into pGEM-T vector. Secondly, the target gene was cut by EcoRI and inserted into restriction sites of pET42a vector for expression.

本研究首先用PCR方法，以pUC18/GAD_(65)为模板，扩增目的基因，克隆到pGEM-T载体中，构建pGEM-T/GAD_(65)重组质粒，然后用EcoRI酶切，切下的目的基因片段插入pET42a融合型表达载体中，经酶切鉴定和测序，证实插入方向、读码框架正确；重组表达质粒转化大肠杆菌BL21(DE_3)中诱导表达，表达产物经亲和层析纯化后获得了融合蛋白GST-GAD_(65)。
