By using the 8 km NASA/GIMMS half-monthly composite NDVI data and climate data in 1982-2003, this paper studied the dynamic changes of the annual mean value and accumulation anomaly of NDVI on the north foot of Yinshan Mountain, as well as the time series relationships of annual mean NDVI with annual mean temperature and annual precipitation.

利用1982-2003年8kmNASA／GIMMS半月合成的植被指数数据和同期气候数据，分析了阴山北麓地区农牧交错带的NDVI年平均值、年累积值距平的动态变化以及NDVI年平均值与年平均温度和年降水的时间序列相关关系。

NASA has estimated that halophytes planted over an area the size of the Sahara Desert could supply more than 90% of the world's energy needs.

61Ppm, REE distribution patterns of apatite standarded by NASA are classified into two types: The one is concave,"hat-shaped" REE pattern which is slightly enriched in intermediate REE and has a weak or even wanting Ce anomaly. To which, the sandy phosphorite of Jile is representative; the rest REE pattern is shown by more or less complete curve, although distinct Ce negative anomaly or weak Ce positive anomaly is shown up well. The stromatolitic apatite is the representative of this type.

其稀土元素北美页岩标准化配分型式主要分为两类：一类为中稀土略显富集的帽状形态的稀土元素配分型式，微弱的铈负异常或无铈异常，以极乐矿段砂屑磷块岩样品最为典型；另一类为轻稀土、中稀土和重稀土自然分异的三段弧形折线衔接而成的稀土元素配分型式，铈负异常较明显或微弱的铈正异常，以叠层石柱体磷灰石最典型。

The Southern Patagonian Icefield of Chile and Argentina hosts several spectacular glaciers, including this, the Grey Glacier located in the Torres del Paine National Park in Chile. It begins in the Patagonian Andes Mountains to the west and terminates in three distinct lobes into Grey Lake. NASA/JSC

南巴塔哥尼亚冰原位于智利和阿根廷境内，有数个壮观的大冰川，其中之一就是图中的灰冰川，位于智利的Torres del Paine国家公园，起于巴塔哥尼亚安第斯山脉，一直绵延向西分成三支至灰湖。
