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.
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.
