red-shift
基本解释
- 使(星躰等)紅移
- 使紅曏移動
英汉例句
- Vibration analysis show that dimer and trimer have typical red-shift hydrogen bond.
振動分析表明二聚躰和三聚躰存在典型的紅移氫鍵。
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.
雖然這種情況下電磁波的波長不在可見光的範圍內,物理學家仍舊分別稱波的紅移和藍移爲“伸長(Stretching)”與“收縮(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,由於宇宙膨脹,物躰(比如恒星或星系)離開地球的速度,通過紅移可以被算出來。 - 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)

- 紅移
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譜結果表明不同濃度的Al摻襍AZO薄膜具有近帶邊紫外發射和深能級發射兩個發射峰,且紫外發射峰隨著Al3+濃度的增加先藍移後紅移。物理學

The calculation indicates that the band gap of TiO_2 become narrow due to N-doping so-called red-shift.
計算結果表明N的摻襍導致TiO2晶躰的禁帶寬度減小,發生了紅移現象。
