英语词汇“recession velocity”的英英意思、用法、释义、翻译、读音、例句、短语、词组-英语词典

h. Astronomy. The motion of a celestial object away from the earth, esp. that of an object outside our galaxy attributed to the expansion of the universe. Also attributive, esp. in recession velocity.Quot. 1841 refers to motion across the field of view (proper motion, rather than radial motion).
