red shift

基本解释

If they go away from you, you see red shift.
如果它远离，你看到红光偏移。
If cosine theta is negative, then the object is receding from you, then lambda prime is larger than lambda, and we call that red shift.
如果cosθ为负数，物体离开你们，λ撇，大于λ,我们叫它红色偏移光。
They like to measure the coming and the going of the speed of objects so they will have red shift or blue shift to know if objects are advancing or retreating from the observer.
他们喜欢测量目标进入和离开的速度，那么他们能得到红移或蓝移量，然后得知目标对于观察者而言是正在前进还是后退。

Even if Amazon and Red Shift become the industry platform, a number of things can still go wrong.
FORBES: And the Winner is, Who?!
The farther away a galaxy is, the faster it is receding and the bigger this red shift will be.
ECONOMIST: Cosmology: I spy with my little gravitational lens The

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)

红移
Study of the spectral characteristics shown that extending the conjugated chain caused a red shift in the UV / vis and FL spectra.
