高人们 帮我翻译下这句话吧? A couple of colonies were suspended in phosphate buffered saline (PBS) and optical density (OD) of the solution at 492 nm was adjusted spectrophotometrically (Multiscan RC, Labsystems, Helsinki, Finland) to 0.1.This OD was found to correspond 1 × 10 8 colony forming units per millilitre (CFU/ml) by quantitative bacterial culture. optical density (OD):光密度 spectrophotometrically :分光光度法?(什么意思啊) phosphate buffered saline (PBS) ( 磷酸盐缓冲液 ) 实在是翻译不来,怎么说也不像句人话!查看更多6个回答 . 1人已关注
