托福词汇之“EVA太空行走”

2015-06-08来源:互联网

  Before the spacewalk, the astronaut shouldering the historic task will needthe help of another to put on a 120kg, non-powered spacesuit for the extravehicular activity (EVA).

  在太空行走之前,承担此项历史重任的航天员要先在另一名航天员的帮助下穿上重达120公斤的无动力舱外活动航天服。

  上述报道中,extra vehicular activity 就是“舱外活动”的英文表达,简称EVA,是我们通常所说spacewalk(太空行走)的专业说法。

  WIK I百科介绍说 Extra-vehicular activity (EVA) is work done by an astronaut awayfrom the Earth and outside of a spacecraft. The term most commonly applies to anEVA made outside a craft orbiting Earth (a spacewalk) but also applies to an EVAmade on the surface of the Moon (amoonwalk),由此可见,“舱外活动”(EVA)还具体分为 spacewalk (太空行走) 和 moonwalk(月球行走)。
