n.多普勒效應(yīng)

Moreover, since the atoms are in random thermal motion the frequency spectrum will be altered by the Doppler effect. 而且，由于原子是在作無規(guī)則熱運動，多普勒效應(yīng)也會使頻譜發(fā)生改變。

To measurte temperature of gas discharge plasma with Doppler effect by using spectrum diagnosis. 討論了用多普勒效應(yīng)測量氣體放電等離子體溫度的光譜診斷方法。
