1.高层大气
2.上层大气
1.the part of the Earth's atmosphere above the troposphere, especially at heights unreachable by balloon
1.The planet and its neighbours are bathed in the solar wind, a stream of charged particles ejected from the upper atmosphere of the sun.
地球与其邻近的行星都处于太阳风（从太阳上层大气层发射出的带电粒子流）的势力范围之内。
2.All that's visible during totality is the sun's relatively faint upper atmosphere, called the corona.
日全食期间能看见的只有太阳上部相对模糊的大气，被称为日冕。
3.A less exotic approach, endorsed by Dr Crutzen, would be to spread tiny particles in the upper atmosphere to reflect the sun's rays.
克鲁特森博士提出并认可了一项较为实际的方案，那就是在大气层的上层散布大量的微小粒子来反射太阳光线。
4.Perhaps a chemical or chemicals in the upper atmosphere are transported to the surface through rain or snow.
大气层上方的某些化学物质通过雨雪降至地面，从而导致孤独症。
5.THE comings and goings of noctilucent or "night shining" clouds in the extreme upper atmosphere may be linked to the sun's rotation.
高层大气中时隐时现的发光的云团可能跟太阳的自转有关。
6.Some, however, are the result of collisions between cosmic rays and the gases of the upper atmosphere.
但有一些则是宇宙射线和外层大气碰撞的结果。
7.Often, the blanket of new oil will drop close to the ground before setting afire, as the oxygen is thin in the upper atmosphere.
通常情况下，新形成的油层在燃烧之前会掉到靠近地面的地方，因为上层大气是稀薄的。
8.Reactions between oxygen and ultraviolet radiation from the sun create a layer of ozone throughout Earth's stratosphere (upper atmosphere).
太阳辐射紫外线和氧反应在整个地球平流层（上部大气圈）内产生一个臭氧层。
9.The plasma dissipated throughout the upper atmosphere, filling the near vacuum with a fading purple haze.
离子束一直射到上层大气，用淡紫色填满了真空。
10.The reason so much ozone has been lost over the Arctic and Antarctic is the presence of chlorine in the upper atmosphere.
北极和南极有如此多臭氧丧失的原因是因为大气上层存在的氯。
