这里为大家介绍下red shift 是什么意思，希望能帮助到各位朋友。

中英文翻译

【天文学】红移，红向移动。

red:n. 镇静剂。 shift:vt. 1.变动；改变；搬移；移动；转移；变换；替换；更 ...(astronomy) a shift in the spectra of very distant galaxies toward longer wavelengths (toward the red end of the spectrum); generally interpreted as evidence that the universe is expanding

同义词：redshift,

例句与用法
