A gas - jet - type vuv source that can give a spectrum in the wavelength range of 5 ~ 200nm was used in this paper to research of vuv radiation effects on upilex films which used as canopy of the space inflatable antennas and al / kapton films 利用射流式真空紫外地面模拟设备研究了5 200nm波长范围内的真空紫外辐照对al / kapton薄膜与空间充气展开天线透射面材料upilex薄膜的性能影响。
