南极

Poor southerners , there is no bright star near the south celestial pole .

可惜的是，天球南极附近没有光星，所以没有南极星为南半球居民引路。

Classification of ordinary chondrite s based on mean Fa and Fs value of olivine and Low-Ca pyroxene respectively is effective.

格罗夫山普通球粒陨石在类型分布上，其比例和南极以及非南极普通球粒陨石有显著不同，说明可能存在相当数量的成对陨石。

An ordinary chondrite(Sample No.GRV052483) was recovered on blue ice during the 22nd Chinese Antarctic Research Exploration in Grove Mountains,Antarctica.

The interaction between Antarctic Circumpolar Current and Antarctic coastal current in the Indian section of the Southern Ocean is investigated in this paper by using numerical and theoretical methods. Especially, The non-zonation of ACC in the region of Kerguelen Plateau and its annual variation are analyzed.

本文利用数值方法对南大洋印度洋扇形区南极绕极流和南极沿岸流的相互作用进行了研究，重点研究了凯尔盖朗海台区ACC的非纬向性特征及其季节变化，对其非纬向性的形成机制进行了理论探讨。

The following key future research fields are needed to understand and predict Antarctic Ice Sheet mass balance: Observation and modeling of the surface elevation changes, determination of surface mass balance and its distribution over drainage basins as well as fluxes at the grounding lines and the bottom melting underneath ice shelves, understanding of the deglaciation history, development, comparison and improvement of all kinds of models related to modeling and prediction of ice sheet mass balance.

南极冰盖物质平衡未来的重点研究领域是开展冰盖表面高程变化的监测与模拟，确定表面物质平衡及其在各冰流盆地的分布，着地线的冰流通量，冰架底部的融化，了解冰后期冰盖退缩的动力过程，以及开发、对比和改进与冰盖物质平衡模拟和预测相关的各种模型。关键词：南极冰盖；物质平衡；进展与展望

Neighbor-Joining analyses of teleost hepcidins showed that the eelpout 4cys variant arose independently from the notothenioid version, which lends support to adaptive evolution of reduced cysteine hepcidin variants on cold selection. The NJ tree also showed taxonomic-specific expansions of hepcidin variants, indicating that duplication and diversification of hepcidin genes play important roles in evolutionary response to diverse ecological conditions.

另外我们在另一种生活于南极水域的eelpout中也发现了一种含有4个半胱氨酸残基的hepcidin，而eelpout和南极鱼notothenioid在分类学上分属于不同亚目，是一类相差较远的物种，利用Neighbor-Joining方法建树分析发现eelpout的hepcidin虽然同样仅含有4个半胱氨酸残基，但和notothenioid的4cys_hepcidin有着不同的起源，这也进一步说明了hepcidin中半胱氨酸残基数目的减少确实是对寒冷环境的一种适应性进化。

The geographic South Pole is at the center of the Antarctic continent, but the magnetic pole is hundreds of miles away, near the coast.

地理南极在南极大陆的中央，但是磁极却离此数百英里，在海岸带附近。
