1.【气】对流层
1.the lowest and most dense layer of the atmosphere, extending 10 to 20 km (6 to 12 mi), in which temperature decreases with rising altitude and most weather occurs
1.The pressure at the top of the troposphere is only 10% of that at sea level and above this layer the pressure continues to drop.
在对流层的顶部压力，只有10%，在海平面以上这一层的压力继续下降。
2.The troposphere is the human home. We live directly in the bottom of the troposphere, and all weather phenomenon takes place on story here.
对流层是人类的家园。我们直接生活在对流层的底部，一切天气现象均发生在此层。
3.At the beginning of the 20th century, Nikola Tesla proposed using huge coils to transmit electricity through the troposphere to power homes.
早在20世纪初，尼古拉·特斯拉就提出利用巨型线圈，通过大气对流层将电输送到千家万户。
4.The line between the troposphere and the rest of the blue-colored atmosphere is called the tropopause.
对流层与蓝色大气中的其余部分之间的分界线，称为对流层顶（tropopause）。
5.From the outside in the sun for a nuclear reaction zone, the troposphere the sun, the sun's atmosphere.
由里向外分别为太阳核反应区、太阳对流层、太阳大气层。
6.The orange layer is known as the troposphere, where all of the weather and clouds are generated and contained.
橘黄色的那一层被称为“对流层”，那里是所有的气候状况和云层形成和演变的地方。
7.The stratosphere begins about 12 kilometres up, above the troposphere where weather systems like the monsoon develop.
平流层大约从距离地面12公里开始，天气系统例如季风通常在对流层上发生。
8.As a rule, the temperature in the troposphere decreases steadily with increasing altitude until the tropopause is reached.
通常对流层温度直到对流层顶都是随高度增加而不断地减小的。
9.The OH radical initiated degradation of ethane was possibly one of the main sources of H2O2, MHP and EHP in the troposphere.
OH自由基引发的乙烷降解反应可能是对流层大气H2O2，MHP及EHP的重要来源之一。
10.The rest is in the stratosphere, from the top of the troposphere to an altitude of 50 kilometers.
其余的臭氧在离对流层顶部至50公里高度的同温层里。
