The experimental result shows that the resonance line w,the magnetic quadrupole M2 line,the intercombination line y and the forbidden line z of He-like Al are obtained with PET crystal in the direction of horizontal.

实验结果表明，PET晶体分光效果理想，获得了铝的类He共振线、磁四级M2跃迁x线、互组合跃迁y线以及禁戒谱线z线，适合于研究X射线极化光谱学；云母晶体得到铝的类He共振线，其伴线光谱不明显。

The main conclusions are the following:1 It is a effective means that making use of the high resolution remote sensing imagery has quickly and dynamically investigated and monitored the land use type ofRed Water River, and has carried through the four grades of classification, and its result has achieved the precision requirement of the minimum area of obvious land use type (cultivated land, field, economic forest) less than 9 pixel of imagery, area precision 9~27 pixel and 0.33 hectares.2 It is a high-efficient and feasible means that making use of the digital managing technology of wave band merging, precise geometry correction, imagery merging, imagery strengthening, imagery cut out and inlay, and making the orthograph, etc, and observing on the spot to data analysis, it has carried on people-computer interactive screen translating to the remote sensing imagery data of high resolution by using many kinds of geographical information systems soft ware.

主要结论如下： 1 利用高分辨率遥感影像进行快速、动态调查与监测红水河流域土地利用类型，并将土地利用类型进行到四级分类，达到重点地类图上最小面积9个像元，面积精度9～27个像元、1.5亩的精度要求，是一种行之有效的方法。
