red-shift

基本解釋

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。

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(nèi)，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.
ECONOMIST: An illuminating burst

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

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