red-shift
基本解释
- 使(星体等)红移
- 使红向移动
英汉例句
- Vibration analysis show that dimer and trimer have typical red-shift hydrogen bond.
振动分析表明二聚体和三聚体存在典型的红移氢键。
http://www.chazidian.com - Although in this case the waves are not in the visible spectrum, physicists still call the stretching and shrinking of the waves red-shift and blueshift, respectively.
虽然这种情况下电磁波的波长不在可见光的范围内,物理学家仍旧分别称波的红移和蓝移为“伸长(Stretching)”与“收缩(Shrinking)”。 - In addition, the speed at which an object such as a star or galaxy is moving away from Earth, because of the expansion of the universe, can be worked out from its red-shift.
此外,由于宇宙膨胀,物体(比如恒星或星系)离开地球的速度,通过红移可以被算出来。 - By measuring the red-shift of the burst's light (something that depends on how fast it is receding from Earth, and thus—because the universe is expanding at a uniform rate—how far away it is), it is possible to work out how bright it really was.

英英字典
- a shift in the lines of the spectrum of an astronomical object towards a longer wavelength (the red end of an optical spectrum), relative to the wavelength of these lines in the terrestrial spectrum, usually as a result of the Doppler effect caused by the recession of the object (Compare blueshift)

专业释义
- 红移
The PL spectra reveal that the NBE-peaks and DLE-peaks are observed in the AZO films with different Al doping concentration. The NBE-peaks show first blue-moved to a later red-shift as Al doping concentration increasing.
PL谱结果表明不同浓度的Al掺杂AZO薄膜具有近带边紫外发射和深能级发射两个发射峰,且紫外发射峰随着Al3+浓度的增加先蓝移后红移。物理学
- 红移
The calculation indicates that the band gap of TiO_2 become narrow due to N-doping so-called red-shift.
计算结果表明N的掺杂导致TiO2晶体的禁带宽度减小,发生了红移现象。
