无信号损耗,空号损耗
The results show that the loss of surfactant is maximum which is about 80% injection after 1/ 5 well spacing migration, and loss of polymer and alkali are only 12% and 15% respectively.
结果表明,活性剂的损失量最大,在运移1/5井距后即损失约80%;而聚合物和碱的损失分别只有12%和15%。
However, in previously reported work with these holographic devices the diffraction efficiency and wavelength selectivity were not so satisfactory, which affected the insertion loss and channel spacing of the device respectively.
但是目前已报导的工作中还存在着衍射效率不高、选择性差等问题,它们分别影响着器件的插入损耗和通道间隔。
