scanning frequency measurement

基本解釋

By counting the number of such X-rays while scanning the frequency of the laser pulse, the team could make a very precise measurement of the photon energy required to drive the 2S-2P transition.
通過(guò)統(tǒng)計(jì)所發(fā)出X光的數(shù)量，然後對(duì)照激光脈沖的頻率，測(cè)量小組能得出一個(gè)非常精確的測(cè)量值，從2S能級(jí)到2P能級(jí)躍遷所需的量子能量。
