A maser is a collection of molecules -- in this case, water -- that amplifies light into a powerful beam. 一個脈澤就是一組分子（在這個話題下就是水分子），它會把光線放大為強大的光束。
In this paper a cesium beam maser is proposed in which the optically pumping state selection technique by two laser beams is used together with the atom storage bulb technique. 本文提出一種銫原子束激射器的建議，其中利用了雙束激光抽運選態(tài)技術(shù)和原子貯存泡方法。
Analyzed the different plasma density, position, thickness, and field intensity influence to the beam-wave interactions in plasma Cerenkov maser. Finally, the curves and dispersion relationships a… 重點分析了等離子體密度、厚度，外加磁場對等離子體切倫可夫脈塞注-波互作用的影響，并計算了各參量變化時的波增長率以及色散關(guān)系。
