废气

This artificially induced plasma depletion can then be used to investigate other space phenomena, such as the growth of the plasma instabilities or the modification of radio propagation paths. The 47 second OMS burn of July 29, 1985, produced the largest and most long-lived ionospheric hole to date, dumping some 830 kg of exhaust into the ionosphere at sunset. A 6 second, 68 km OMS release above Connecticut in August 1985, produced an airglow which covered over 400,000 square km.

这一人工诱导离子损耗之后能够被用于研究其他的太空现象，比如离子不稳定性的增长或者无线电传播通道的改变。1985年7月29日47秒的轨道操纵系统的燃烧产生了迄今为止最大和最长期的电离层空洞，将大约830公斤的废气在日落时倾倒入电离层。1985年8月康涅迪格上空6秒种、68公里的轨道操纵系统的排放产生了覆盖40万平方公里的气辉。

两年前，泰姬陵就进行了一次表面大清洗，清除了许多陈年污渍和尘垢。困扰泰姬陵的污浊空气来源于分布在其周围的数千家钢铁厂、砖瓦厂和玻璃厂的废气。

We have no common name for a mime of Sophron or Xenarchus and a Socratic Conversation; and we should still be without one even if the imitation in the two instances were in trimeters or elegiacs or some other kind of verse--though it is the way with people to tack on 'poet' to the name of a metre, and talk of elegiac-poets and epic-poets, thinking that they call them poets not by reason of the imitative nature of their work, but indiscriminately by reason of the metre they write in.

索夫农 、森那库斯和苏格拉底式的对话采用的模仿没有一个公共的名称；三音步诗、挽歌体或其他类型的诗的模仿也没有——人们把&诗人&这一名词和格律名称结合到一起，称之为挽歌体诗人或者史诗诗人，他们被称为诗人，似乎只是因为遵守格律写作，而非他们作品的模仿本质。
