新疆昭苏水磨沟铜金矿特征

新疆西天山下石炭统大哈拉军山组地层中产有众多的金矿体。通过对昭苏水磨沟铜金矿床矿化特征的研究 ,总结出这类矿床的成矿规律是 :下石炭统大哈拉军山组中酸性火山岩是矿源层 ;区域性大断裂是矿质运移通道 ,其中的低级别、低序次构造为容矿空间 ;华力西期钾长花岗岩是形成铜金矿的能量来源 ;绿片岩相以下的动力变质作用是矿化富集的条件。矿床成因应属构造破碎蚀变岩型铜金矿床     

大漠深处的"桃花源"

塔克拉玛干是我国最大也是世界著名的大沙漠，几个世纪以来，一直被人们视为死寂恐怖的不毛之地。当地人称它“进去出不来”，西方探险家干脆叫它为 “死亡之海”。然而，“刀朗人” 却奇迹般地生存在大漠深处，他们有自己独特的方言和生活习惯，过着近乎“与世阳绝”的“桃花源”式的生活。 沙漠深处的生命奇远 第一天，由乌鲁木齐乘飞机到达南疆古城喀什后，我们便转乘越野车直奔小城麦盖堤，然后从这里骑骆驼进入塔克拉玛干沙漠。 这里简直是沙的世界！一道道沙梁，一座座沙山，看到的除了黄沙还是黄沙。面积３３万平方公里的塔克拉玛干…     

新疆伊犁地区棉铃虫发生与环境因子的关系及其防治技术的研究

1997－1999年连续3年新疆伊犁地区棉铃虫大发生，对上述棉铃虫大发生年份的环境因子进行了相关分析，并对棉铃虫的防治进行了初步试验研究，结果表明，环境因素对棉铃虫的发生有直接的影响作用。     

新疆农村改水综合效益研究

新疆改水工程大大改善了农村饮水条件，使介水传染病发病率减小，环境及生活习惯都发生了可喜变化，为此，对包括减轻取水负担、节省医药费负担、发展庭院经济和水厂效益在内的直接经济效益进行了动态量化分析研究，提出了估算公式，同时根据翔实可靠的数据进行了保守计算，综合效益研究表明，新疆农村改水效益十分显著，至2000年底新疆农村改水的累计总经济效益达到55．07亿元以上，远远超过累计21．63亿元的总投资。     

新疆蜗牛酶的研制

以野生蜗牛嗉囊为原料提取蜗牛酶产品,检测所含纤维素酶、淀粉酶的活性,对其蜗牛酶产品进一步测试,结果表明新疆蜗牛酶中的纤维素酶活力为450U/g淀粉酶为405U/g。验证了新疆蜗牛酶中纤维素酶的活力很高。     

认知语言学视角下的新疆少数民族学生汉语介词习得

在新疆诸多少数民族语言中，没有介词这一词类，介词向来是新疆少数民族学生汉语学习中的难点。我们在调查的基础上，从认知语言学的角度探究新疆少数民族学生汉语介词习得问题，以有标记与无标记、总括扫描与次第扫描等概念为切入点，以认知为最终的解释，以期对学生的一些偏误现象做出合理的概括和解释。     

新疆玛纳斯县第一中学

Petrology, geochemistry and geodynamics of basic granulite from the Altay area, North Xinjiang, China

The basic granulite of the Altay orogenic belt occurs as tectonic lens in the Devonian medium- to lower-grade metamorphic beds through fault contact. The Altay granulite (AG) is an amphibole plagioclase two-pyroxene granulite and is mainly composed of two pyroxenes, plagioclase, amphibole and biotite. Its melano-minerals are rich in Mg/(Mg Fe^2 ),and its amphibole and biotite are rich in TiO2. The AG is rich in Mg/(Mg Fe^2 ), Al2O3 and depletion of U, Th and Rbcontents. The AG has moderate ∑REE and LREE-enriched with weak positive Eu anomaly. The AG shows island-arc pattern with negative Nb, P and Ti anomalies, reflecting that formation of the AG may be associated with subduction. Geochemical and mineral composition data reflect that the protolith of the AG is calc-alkaline basalt and formed by granulite facies metamorphism having peak P-T conditions of 750℃-780℃ and 0.6-0.7 Gpa. The AG formation underwent two stages was suggested. In the early stage of oceanic crustal subduction, calc-alkaline basalt with island-arc environment underwent granulite facies metamorphism to form the AG in deep crust, and in the late stage, the AG was thrust into the upper crust.     

新疆若羌县赤石山变质核杂岩研究

新疆北山裂谷带西缘若羌县赤石山地区存在大型变质核杂岩构造。其下拆离盘为古元古界结晶基底杂岩 ,上拆离盘为中元古界白湖群变质岩系 ,滑脱拆离带为已变形的大型韧性正断层。核杂岩南、北侧发育上叠盆地 ,北侧形成“年轻”正断层及同构造期岩浆岩。变质核杂岩的形成与晚古生代北山陆内裂谷区域伸展有直接联系。该区变质核杂岩的首次厘定 ,对深化北山裂谷的研究具有重要意义     

Degradation of pyrene and characterization of<Emphasis Type="Italic">Saccharothrix</Emphasis> sp. PYX-6 from the oligotrophic Tianchi Lake in Xinjiang Uygur Autonomous Region,China

Bacterial strain PYX-6 that utilizes anthracene,phenanthrene, or pyrene for carbon and energy sources for growth was isolated from a non-polluted lake (Tianchi Lake) in Xinjiang Uygur Autonomous Region of China. Its morphology, physiological and biochemical properties, cell wall pattern and G C mol% content of DNA molecules were characterized. The 16S rRNA gene of strain PYX-6 was sequenced and analyzed for similarities to related bacterial species. Results indicated that strain PYX-6 is a member of the Genus Saccharothrix, and the strain was named Saccha-rothrix sp. PYX-6. When pyrene was the sole carbon source in cultural medium, the strain PYX-6 assimilated pyrene for growth and 0.005% of yeast extract stimulated pyrene degradation and assimilation. The optimal pH of cultural medium and the optimal shaking frequency during cultivation were 6-8 and 200 r/m, respectively. It was found that the disappearance of pyrene in medium occurred before significant growth of strain PYX-6 took place. Phthalic acid, benzylacetic acid, and benzylpropenoic acid were detected as catabolic intermediates during pyrene degradation with mass spectroscopy and this result indicated that Saccharothrix sp.PYX-6 adopted a pathway that is different from the pathway of the previously reported pyrene-degrading Mycobacterium sp. PYR-1.
