上层大气

These dazzling patterns in nature, called aurora australis in the Southern Hemisphere, are created when charged particles outside the Earth's atmosphere collide with atoms in the upper atmosphere, producing a glowing display of curtains, arcs, and bands stretching across the sky.

这些眼花缭乱的模式在自然界，在南半球叫南极光，其创造是带点粒子在地球大气的外面和原子相碰撞在上层大气，产生一个通红的门帘的显示，弧形，和线索延伸横过天空。

Moreover, the nuclear radiation was not confined to the upper atmosphere: caribou and people who survived were dangerously contaminated with caesium 137, and cancer, lung disease and infant mortality soared.

而且，核辐射并不局限于上层大气，生存下来的北美驯鹿和人类危险地受到了铯137的污染，以及癌症、肺病和新生儿死亡率激增的危害。

But the healing process is slow: Since the early 1980s changes in the upper atmosphere caused by ozone depletion have intensified circumpolar winds that whistle around Antarctica.

但是臭氧层的恢复过程很缓慢：在20世纪80年代初，由上层大气臭氧层削减造成的上层大气的变化加剧了南极洲的极地风。

At last, we have found that the neutral line is more complicatedly and widely spread on the lower slab than that on the upper one.

最后，我们发现上下两层大气的矢量磁场的中性线分布是不一样的，在下层磁场中性线要比上层大气复杂的多。

The first successful radio range-finding experiment occurred in 1924, when the British physicist Sir Edward Victor Appleton used radio echoes to determine the height of the ionosphere, an ionized layer of the upper atmosphere that reflects longer radio waves.

首次成功的无线电范围内调查试验发生在1924年，当英国物理学家尤德爵士维克多阿普尔顿使用的无线电回波，以确定高度，电离层，电离层的上层大气，反映了较长的无线电波。

The atmosphere in the high layer are ionized by the solar UV and X-ray.

由于太阳紫外线，X射线辐射致使高空上层大气电离。

This indicates that the magnetic loops connecting the two umbrae are more spread upwards.

这表明此δ型黑子的磁环从下层大气到上层大气继续延伸。

On the other hand, comparing the zeniths of vectors in.the two umbrae, these in the upper layers are more vertical than those in lower layers on average.

另一方面，对比了黑子两个本影在上下两层大气的磁倾角分布显示，在上层大气本影磁力线更竖直一些。

"Its mean density is only about 0.2 grams per cubic centimeter, or about the density of balsa wood," said study leader Georgi Mandushev of the Lowell Observatory in Arizona.

&其平均密度只有约每平方厘米0.2克，或者说相当于轻质木材的密度，&研究小组组长、亚利桑那州洛厄尔天文台的乔吉·曼德舍夫说，&由于该行星对上层大气的引力相对较小，很可能其中部分大气呈慧尾状而逃逸掉。&

The interference image spectroscopy coupled with the Doppler effect of electrical and magnetic waves are employed to measure the natural airglow and auroral visible emission lines in the upper atmosphere.

以上层大气中的气辉为被探测源，利用干涉成像光谱技术和电磁波的多普勒效应对上层大气风场进行测量，分析和计算了大气风场的速度和温度，并就被探测源和探测器之间的相对速度与其连线成任意角时的情形进行了讨论。

On the other hand, the more important thing is because the urban housing is a kind of heterogeneity products.

另一方面，更重要的是由于城市住房是一种异质性产品。

Climate histogram is the fall that collects place measure calm value, cent serves as cross axle for a few equal interval, the area that the frequency that the value appears according to place is accumulated and becomes will be determined inside each interval, discharge the graph that rise with post, also be called histogram.

气候直方图是将所收集的降水量测定值，分为几个相等的区间作为横轴，并将各区间内所测定值依所出现的次数累积而成的面积，用柱子排起来的图形，也叫做柱状图。
