常見(jiàn)例句
- Not until the development of radio astronomy in the fifties was there incontrovertible experimental verification, but essentially these years of practical striving were irrelevant.
直到五十年代，由于射電天體測(cè)量學(xué)的發(fā)展，實(shí)驗(yàn)證明才提供了無(wú)可爭(zhēng)議的證據(jù)，而事實(shí)上，這么多年的實(shí)踐努力并無(wú)多大意義。
