A design for screening military electronic machines using dual-layer composite of attenuating materials and metals instead of single metallic layer is proposed in this paper.
提出用吸波材料与金属材料双层复合代替单层金属材料对军用电子仪器进行屏蔽的设计。
With an increase of reduction time, the reduced metallic layer became thicker, which showed that the plasma hydrogen enhanced the reduction ability of hydrogen for metal oxide.
随着还原时间的增长，等离子态氢还原氧化物得到的金属层厚度增加。这表明等离子态氢能强化氢还原金属氧化物的能力。
Its optical density, with help from a metallic layer, has been achieved at 5.5. Since this organic material is a negative photoresist, the fabrication process is rather simple.
借助金属层，其光学密度已达到5.5。由于这种有机材料是负性光敏抗蚀剂，所以加工过程相当简单。
