②随着啁啾系数增大，透射谱带宽增大，透射率降低，滤波性能变坏；
The transmission spectrum bandwidth increases with the chirp parameter, while the transmission decreases, which leads to worse filter feature;
采用级联多个长周期光纤光栅的方法有效拓宽了长周期光纤光栅反射谱带宽。
An improved method of cascaded long-period fiber gratings (LPFGs) is proposed, which can effectively broaden the resonant spectrum bandwidth of LPFGs.
多孔硅的性能不稳定，且反射谱带宽很大，所以利用多孔硅的反射谱漂移探测有机气体，会给实验带来很大的误差。
Due to instability and large line-width, detecting organic gases with reflectance shift of porous silicon directly brings serious error to experiments.
