大气层

This paper discusses the theory method calculating surface temperature of ballistic target above aerosphere, and analyses the effect of dimensional orientation of target s flight gesture and sun radiation direction on its surface temperature.

论述了大气层外弹道式目标表面温度的计算方法，对某弹道式目标大气层外飞行过程中当太阳辐射方向改变时其表面温度的变化情况进行了数值计算，分析了目标飞行姿态与太阳辐射方向之间空间方位关系的变化对目标表面温度的影响。

Since the attenuation of the free-space channel between ground and satellite is contributed by the aerosphere, its equivalent length is about 5 km and the total attenuation of round-trip is equivalent to 10 km free-space channel in the earth surface aerosphere.

由于地面-卫星之间的自由空间信道的衰减主要集中在地面大气层，其等效厚度约为5km，往返两次的信道衰减等效于地面大气层的10km。

Normally 100 kilometre ～ the aerosphere under 120 kilometre calls dense aerosphere, the; of the 3rd environment that also calls atmosphere environment or mankind and 120 kilometre above calls 100 kilometre ～ the 4th annulus of deep space or mankind

通常把100千米～120千米以下的大气层称为稠密大气层，也称为大气环境或人类的第三环境；而100千米～120千米以上称为外层空间或人类的第四环

The plane lifts quickly, pass through aerosphere, at this moment air man shuts engine, passenger and unit staff have weightlessness feeling, after this kind of case lasts about two minutes, the plane returns aerosphere, the plane is quickened afresh.

飞机迅速升高，穿越大气层，这时飞行员关闭发动机，乘客和机组人员有失重感，这种情形持续大约两分钟后，飞机返回大气层，飞机重新加速。

These dazzling patterns in nature, called aurora australis in the

这种大自然的光秀，在南半球称为aurora australis ，系地球大气层外围的带电粒子与大气层上部的颗粒相撞而成，色彩往往令人叹为

We obtain a parameterized description of weather with the meteorological data. The study is focused in visible spectrum and the optical features of atmosphere, especially the influence of airborne media on imaging.

在大气层的太阳辐射方面，讨论不同季节的大气层外的太阳辐射，以及大气层对太阳辐射的吸收、散射与漫射作用；根据天空参数得到了一个天气参数化的描述。

The reason of this is that near the horizon we look through a very great thickness of the lower atmosphere, which is full of the larger dust particles reflecting white light, and this diluter the pure blue of the higher atmosphere seen beyond, And in the vicinity of the sun a good deal of the blue light is reflected back into space by the finer dust, thus giving a yellowish tinge to that which reaches us reflected chiefly from the coarse dust of the lower atmosphere.

这是因为我们向天边望去时，目光要穿过极厚的低空大气层，其中布满颗粒较大的尘埃，反射出白光，这就冲淡了天际高空大气层的纯蓝色。在太阳附近，大量蓝光则由细微的尘埃反射回太空。这样，主要由低空大气层的粗粒尘埃反射到地面的光线，便带有浅黄色。

These problems involve primarily the oceans and atmosphere—the commons which are shared by all and are the basis of our life-support system.

这些问题主要涉及海洋和大气层，而海洋和大气层是人类所共有的，是维持生命系统的基础。

Venus is a rocky world that is about the same size as Earth. But its climate is anything but Earth-like. It is a cloud-covered world where temperatures reach over four hundred degrees Celsius. The atmosphere of Venus is so thick that the pressure at the surface is about one hundred times that of Earth.

金星是一个岩石世界，它的大小与地球差不多，它是一个被气温高达摄氏400度高温的大气层所覆盖，金星大气层是如此之厚实，这种大气层给金星地面所带来的压力是地球大气层对地面带来的压力的100倍。

In the negative and interrogative forms, of course, this is identical to the non-emphatic forms.

。但是，在否定句或疑问句里，这种带有"do"的方法表达的效果却没有什么强调的意思。

Go down on one's knees;kneel down

屈膝跪下。。。下跪祈祷
