Therefore, it is intensity required that unite the pulse design with antenna, so that the spectrumofradiation pulse which radiation by antenna will meet the requirement of FCC mask.
因此必须联合天线与脉冲信号设计，才能使辐射脉冲信号满足FCC频谱规划要求。

The researchers tested their new black material with near-infrared radiation, just beyond the red end of the visible spectrum.
研究人员们使用仅仅超出可见光谱红端的近红外辐射测试他们的新“黑材料”。

Because these different forms of electromagnetic radiation - on this "simplistic" level - are fundamentally so similar, they are today commonly viewed as composing a single spectrum.
