The following results are made from this research: Assessing data quality and band combination of different bands in line with geo-target features in desertification areas, and determining basic bands for desertification monitoring. And understanding and studying the spectral features and variation rules of geo-targets in the experimental area, raising that it is the basis of geo-targets information collection with imaging spectrometer data to understand spectral features and variation rules of geo-targets, realizing that in a great extent spectral-integrated-form-based classification method can remove the phenomenon of "different spectrum with same objects" resulted from reflection ratio curve translation because of the angle change among sensor, targets and observation direction, and the average and variance images can be introduced to solve the problem of two kinds of geo-target with similar spectral forms and much different values of whole reflectionratio. It is suggested that "red edge" range bands of vegetation, which has close relationship with vegetation cover and biomass, is the main characteristic bands and important basis for careful vegetation classification and quantitative retrieval, and pixel-based derivative spectral analysis is very useful for removing the effects of soil background values and quantitatively retrieving vegetation biomass and cover. The remote sense quantitative retrieval model is developed for main appraisable factors of desertification monitoring assessment with imaging spectrometer data and then the applicability of model is analyzed.

研究结果如下：首先针对荒漠化地区的地物特征，对高光谱数据不同波段的数据质量、波段组合进行了评价，提出了适用于荒漠化监测的基本波段选择集；初步了解和掌握了研究地区的地物光谱特性及变异规律，进一步明确了掌握地物光谱特征和变异规律是用成像光谱仪数据提取地物信息的基础；发现了基于光谱整体形状的分类方法在很大程度上能够消除由于传感器、地物目标观测方向之间的角度变化引起的反射率曲线整体平移的&同物异谱&现象，对于谱形相似而整体反射率的值相差较大的两类地物，通过引入均值和方差图像参与分类得到解决；研究还表明在植被&红边&范围内的波段是进行荒漠化监测的主要特征波段，这些波段与植被生物量和盖度都有密切的关系，是开展精细植被分类研究和植被定量反演的重要基础；像元的导数光谱分析可以消除土壤背景的影响，是进行植被生物量和盖度定量反演的有力工具；建立了荒漠化监测主要评价因子的定量反演模型，并分析了模型的适用性。

The technologies such as the clustering diamond cutting tool in the fine machine and the reasonable cutting tool angle parameters, designing appropriable clamp that increases the oriented accuracy and reduces the strain of the work piece, the natural aging that releases the stress of the coarse machine and increases the accuracy of the part shape tolerance,...

And in the light of Euramerican wait for a developed country, virtual Earth technology has comparatived careful, not only can consult simply street information, still can with 3D form bird's eye week meets with real environment, wait like building, arboreous, road.

而针对欧美等发达国家，Virtual Earth技术已经相当精细了，不但可以简单查阅街道信息，还能以3D形式鸟瞰周遭真实的环境，如房屋、树木、道路等。

It possesses the same flanging tinny hi-hats and gothic echoes, but brings much of the bounce and swing absent on "Hot Knives" in its wonky arpeggiated melody.

虽然与曲目&Hot Knives&一样，在这首作品中，Slam乐队也采用了精细的高保真音乐效果以及哥特式的鬼魅旋律，不过，音乐演绎中的起起伏伏倒是让人眼前一亮，也避免了曲目&Hot Knives&中旋律空洞的缺陷。

Recent years, with the development of modem grown technology insuperthin layer material (e.g. MBE and MOVCD) and various super-elaborate artifactitious technology, the study in small scale semiconductor microcavity arouses people\s interests.

近年来，随着现代超薄层材料生长技术(以分子束外延MBE和金属有机化合物汽相淀积MOCVD等技术为典型代表)和各种超精细加工技术的发展，小尺度半导体微腔的研究引起人们的兴趣。

According to the results on cathode luminescence and scan microscope, the secondary enlargement of quartzs was to be the third degree and autogenetic kaolinite was well developed.

另外，应用精细的单井盆地模拟，在埋藏史的基础上模拟孔、渗的垂向变化，可以直观而较为准确的分析垂向上多个储盖组合的相互差异与特征。

Brown's balance between club-ready dance tunes and smooth love balladry is finely honed here, and while the longevity of the singer's career is still uncertain (Brown was shy of 20 years old when the record was released), EXCLUSIVE proves his debut was no fluke.

Brown在专为club预备的舞曲和柔滑的情歌之间的平衡感在这张专辑中得到精细地磨练，但同时他的歌手生涯是否能够长期延续下去仍不确定（当唱片发行时Brown还差一点才满20岁）， EXCLUSIVE证实了他首张专辑的成功并非偶然。
