In addition, it required to measure and analyze the beamspectrum while the experiments of accelerator physics and study on the beam instability are made.
另外在加速器物理实验以及在研究各种束流不稳定性的机器研究过程中，都需要频谱测量和频谱分析。

So we've got a spectrum of a beam of sunlight and it looks like the colors bleed into each other.
我们得到了一束太阳光的光谱，它看起来像是颜色在互相渗透。
