查询词典 Antarctica

The supposition planetoid's diameter probably is 1000 meters, but also the supposition it happen to bumps into the South Pole and the antarctica mainland.

假设小行星的直径大约为1000米，还假设它正好在南极与南极洲大陆相撞。

At the location of the south polar vortex for the normal year, the mixing ratios of O3 and CH4 increased, HCl and NO decreased, but NO2 and H2O did not accord with a given rule at all altitudes over Antarctica in 2002, which was related to the change of the vortex and the dynamical transportation after the SSW, and affected by the reduced polar stratospheric clouds and weakened processes of heterogeneous chemistry.

通过比较还发现，在通常年份极涡所处的位置上，2002年O3和CH4的混合比有所增加，HCl和NO的混合比有所减少，而NO2和H2O在不同高度上的变化特点不同。这与爆发性增温之后极涡和动力输送的变化有关，同时由于增温导致极地平流层云中相关冰相反应的减弱也是一个重要的原因。

Poe's longest work, the 1838 novel Arthur Gordon Pym, described in diary form a series of episodes on a journey to Antarctica.

爱伦坡最长的工作， 1838年阿瑟高登皮姆小说中描述的日记体形式的一系列事件的旅程南极洲。

In geographical distribution, the retrievabilities are low in the low latitude marine regions and in some regions in Antarctica, and relatively high in mid-high latitude regions and continental regions. This partly represents the relationship between retrievability and the variability of temperature.

从地理分布讲，低纬海洋地区和南极洲的部分地区可反演度最小，中高纬和大陆地区较大，反映出和温度变率的关系。

Based on the cognition, a method is developed to assess the retrievability of temperature and the distribution of the global retrievability with HIRS/3 and AIRS data in Jan and Jul are firstly given by using the NCEP reanalysis data. The results show that the retrievability of temperature is low in the upper and lower atmosphere, and high between 400 hPa and 850 hPa. In geographical distribution, the retrievabilities are low in the low latitude marine regions and in some regions in Antarctica, and relatively high in mid-high latitude regions and continental regions.

基于这样的认识，本文首先利用奇异值分解方法结合经验正交分解技术，导出一种计算大气温度可反演度的方法，并利用NCEP再分析资料首次给出了全球1月和7月分别由HIRS/3和AIRS资料反演大气温度廓线时的可反演度分布，结果表明温度的可反演度在高层和低层较小，400hpa—850hpa之间较大。

Study of sapphirine and related mineral association in the high-grade region of the Larsemann Hills, East Antarctica, shows that sapphirine of the area is characterized by its magesio, iron-and aluminum-rich, but silico-poor feature, and the substantial intra-and intergrain changes in compositions. The change is mainly manifested by the Tschermark substitution + Si = 2Al.

通过对南极拉斯曼丘陵含假蓝宝石矿物及有关组合的研究，得知假蓝宝石的成分以富镁、铁、铝但贫硅为特征，其粒间及粒内成分的变化均较为明显，这种变化主要表现为以钙契尔马克代换+ Si = 2Al为主的类质同象置换。

In 2002, a iceberg about 200 km long broke off from Antarctica's Ross Ice Shelf.

2002年，冰山约200公里长的挣脱了南极洲的罗斯冰架了。

An ice shelf of 5,000 square miles in western Antarctica has started to collapse, scientists said.

科学家说，西南极洲5000平方米的冰架开始坍塌。

Several rivers of the West Antarctica ice sheet flow into the ice shelf.

南极洲西部几条河流中的冰块漂流到冰架

That formed here, on this ice shelf in Antarctica.

同南极的冰架情形一样

According to the clear water experiment, aeration performance of the new equipment is good with high total oxygen transfer coefficient and oxygen utilization ratio.

曝气设备的动力效率在叶轮转速为120rpm～150rpm时取得最大值，此时氧利用率和充氧能力也具有较高值。

The environmental stability of that world - including its crushing pressures and icy darkness - means that some of its most famous inhabitants have survived for eons as evolutionary throwbacks, their bodies undergoing little change.

稳定的海底环境─包括能把人压扁的压力和冰冷的黑暗─意谓海底某些最知名的栖居生物已以演化返祖的样态活了万世，形体几无变化。
