So it should be considered that characteristic of spectral information of dust storm in some wavelength region.

组成沙尘暴的沙尘粒子半径分布较广，必须考虑多个光谱波段的遥感特性。

In this paper, effects of atmospheric factors to Ka-Band earth-space links are analyzed, and the total fade distribution function is derived. With the scintillation prediction model, monthly averaged standard deviations and monthly percentage time averaged fade of scintillations for some of referential earth stations of our country are computed.

For predicating the Pb concentration in soil, a partial least square regression modelwas established with 6 optimal factors and two closely relevant electron volt ranges: 10.40-10.70 keV and 12.41-12.80 keV.

模型所用的光谱范围为与土壤中Pb元素密切相关的两个波段： 10.40～10.70 keV和12.41～12.80 keV；最佳主成分数为6。

It indicates that the extinction capability and concentration of bubble solvent can seriously influence the light absorption in some wavebands, bubbles can change the direction of light propagation and reduce the energy density, the transmission intensity and light energy decrease rapidly with the increase of times that the light passes through the bubbles, and bubbles′ floating nature can cause the uncertainty in the emergent ray direction and energy distribution.

结果显示：泡沫溶液的溶质/溶剂的消光能力、浓度等对特定波段光波的吸收产生关键影响；泡沫通过改变光线的传播方向，大大分散出射光线的能量密度；随着光线穿过泡沫液膜界面的次数增多，透射光强迅速衰减，透射能量迅速下降；其漂浮运动还将导致出射光线方向和能量密度分布的不确定性。

At visible wavelengths, the strongest emission line in this pattern is in the red part of the spectrum and is known as "Hydrogen-alpha" or just H-alpha.

在可见光波段，特征谱线中最强的发射线是光谱中红端的部分，就是人们熟知的"氢—α"或"H—α"。
