The feasible number of the first classification and the appropriate pattern of recoding can be used in the process of grassland desertification remotesensing monitoring in Inner Mongolia.·-Renverse principal component analysis is a kind of technique to decrease correlation and stand out the useful information.

主成分变换一逆变换处理是是一种数据压缩和去相关技术，主要目的就是把原来多波段图像中的有用信息集中到数目尽可能少的新的主成分图像中，并使这些主成分互不相关，从而突出有效信息。

测量结果表明该仪器光谱响应稳定性好于1％/年，太阳/大气紫外波段光谱辐照度测量值不确定度好于3～5％。

A method of designing antireflection coatings by the way of Rugate coatings was presented. The reason of difference of transmittance was analysed under the circumstanes of polarization and board angle incidence. Antireflection coatings of 1500-1600nm and incidence angle from 0° to 80° were designed. A new way of design was founded.

阐述了利用Rugate膜系理论设计宽角度减反射薄膜的方法，从理论上分析了在宽角度的情况下，偏振产生透过率不同的原因，模拟设计了光谱区在1500-1600nm波段，入射角从0度到80度宽角度减反射薄膜，探索出了一条新型膜系设计的途径，其优化结果是较为理想的。

The water body was extracted by combining density slicing of TM 5 or TM 7 with the terrain mask produced by DEM. NDVI was used to extract vegetation information, and desertification land and salification land information was extracted by the SAM classification method. Confusion matrix shows that the classification precision is 86.2%.

对TM5/TM7波段进行密度分割，结合DEM数据生成的模板提取水体及盐漠信息；利用NDVI提取植被信息；通过光谱角分类法提取沙化土地和盐渍化土地信息。

The very raw sound fits perfectly within the rather limited musical spectrum of the band just as the screamy vocals of new kid on the block Kenny Winter.

非常原始的声音完全符合在相当有限的音乐谱波段正如screamy歌唱新孩子的块肯尼冬季。

From the reason of speckling, this paper analyses the degree of speckles in UHF/VHF band SAR images.

This paper introduces a facility for automated spectroradiometric calibrations with wide wavelength range, developed by NIM.

本文介绍由中国计量科学研究院研制的宽波段光谱辐射自动测量装置。

Spectroscopically active in the THz region. In te rm of expected detectivity, THz-TDS shou ld not be

另外，由于许多气体反应中间体如 OH、CH、CO 等粒子在THz 波段有较强的吸收特性，因此THz

The results of spectrum analysis show that, the absorption of sulfite cooking liquor during 460nm-580nm visible wavelength mainly comes from sulphonated lignin while saccharide and water in cooking liquor has little.

通过对亚硫酸盐和硫酸盐纸浆卡伯值光谱法在线测量机理的研究发现，亚硫酸盐法蒸煮液在460nm-580nm的可见光波段内的吸收主要是来自其中的磺化木素。
