We analyse the long term periodic variation and nonperiodic variation in atmospheric temperature, density, O2(1.27μm) airglow, OH(1.6μm)airglow and OH(2.0μm)airlow observed by SABER during 2002-2007 using Lomb-Scargle periodogram method and harmonic fit method.
4.利用SABER在2002-2007年间的测量资料,借助LS谱分析方法和谐波拟合法分析了大气温度、密度、O2(1.27μm)、OH(1.6μm)和OH(2.0μm)气辉辐射中的长周期波动特征和非周期变化特征。

得到气管内的气体在一个呼吸周期非定常条件下的流动变化,模拟结果与实验观察相吻合。
The results of the change of flow during a single respiratory period were matched with the observance of experiment by other authors.
当非均匀应变场作用在光纤布拉格光栅(FBG)上时,由于FBG周期和有效折射率在沿FBG长度方向都为变量,所以会导致光谱形状的变化。
The spectrum of fiber Bragg grating(FBG) in inhomogeneous strain fields is distorted due to its inhomogeneity of both the periods and the effective refractive index.
