摘　　要：对灰色、砖红色、深浅迷彩色四种屏蔽布的屏蔽性进行了太赫兹光谱实验研究,得到了这几种屏蔽布的屏蔽效能曲线。实验表明,这几种屏蔽布对太赫兹辐射有很好的屏蔽效能,尤其是灰色屏蔽布的屏蔽效能较好,可用于航空航天及军用仪器设备的屏蔽。若将此类屏蔽布应用在太赫兹波段会有较好的屏蔽效果,会给相应的太赫兹辐射侦查探测带来很大的困难。The terahertz spectra of four stealthy cloths including gray shielding cloth, brick-red shielding cloth, light and dark calibration shielding cloth were studied experimentally, the shielding effect is discussed. Results show that these four shielding cloths have a good shielding effect to terahertz radiation;especially the gray shielding cloths has a better effect,it will bring difficulty for terahertz detection,if they are applied on aerospace or military equipments.
