The unfolded spectra are roughly alike, but N band lines in the spectra unfolded by TGS are too small in comparison with O band lines.

它们的回推谱形大致符合，只是透射光栅谱仪的复原谱的N带相对于O带太小。

In comparison with that of the bulk Ge crystals, the nanocrystalline Ge show a blue shift of energy and the optical band gap increases with decreasing of the particle size of the nanocrystallites.

研究表明：镶嵌在绝缘介质薄膜中的纳米锗颗粒的能带是量子化的，随着纳米锗粒子平均尺寸的减小，其吸收带隙增加，吸收带边蓝移的程度相应增大。

By comparison of injection wave type, it can be concluded that te type wave is easier to be limited to transmit in the structure of the band gap photonic crystal fiber which designed in this article.

通过对注入波类型的比较，可以得出结论，TE类型的波更易于限制在本文所设计的这种结构的带隙型光子晶体光纤中进行传播。
