1.【气】热(成)层
1.the region of the atmosphere above the mesosphere in which temperature steadily increases with height, beginning at about 85 km (53 mi) above the Earth's surface
1.The thermosphere, which blocks harmful ultraviolet rays, expands and contracts regularly due to the sun's activities.
热层可以阻止有害的紫外线，根据太阳的活动定期扩大和收缩。
2.The thermosphere interacts strongly with the sun and hence is greatly influenced by the sun's solar activity, which occurs in cycles.
强烈的热层与太阳交互作用，因此受较大的周期发生的太阳活动影响。
3.Still, the collapse of the thermosphere was bigger than the sun's activity alone can explain.
尽管如此，该热层塌陷是比太阳的活动可以解释的理由还要剧烈。
4.The temperature rises rapidly to between 500k and 2000k in the region known as the thermosphere.
在称之为“热层”地区域内，温度很快上升到500K与2000K之间。
5.This is the biggest contraction of the thermosphere in at least 43 years.
这是至少在43年中最大的热层收缩。
