  1. 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 reflection ratio. 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

    研究結果如下:首先針對荒漠化地區的地物特徵,對高光譜數據不同波段的數據質量、波段組合進行了評價,提出了適用於荒漠化監測的基本波段選擇集;初步了解和掌握了研究地區的地物光譜特性及變異規律,進一步明確了掌握地物光譜特徵和變異規律是用成像光譜儀數據提取地物信息的基礎;發現了基於光譜整體形狀的分類方法在很大程度上能夠消除由於傳感器、地物目標觀測方向之間的角度變化引起的反射率曲線整體平移的「同物異譜」現象,對于譜形相似而整體反射率的值相差較大的兩類地物,通過引入均值和方差圖像參與分類得到解決;研究還表明在植被「紅邊」范圍內的波段是進行荒漠化監測的主要特徵波段,這些波段與植被生物量和蓋度都有密切的關系,是開展精細植被分類研究和植被定量反演的重要基礎;像元的導數光譜分析可以消除土壤背景的影響,是進行植被生物量和蓋度定量反演的有力工具;建立了荒漠化監測主要評價因子的定量反演模型,並分析了模型的適用性。

The fifth part is the reflection on the educational ideas of the western nationalism, in doing so, the analysis and reflection are given to the various modes of the educational ideas of the western nationalism, and then the changing rules of the educational ideas of the western nationalism are concluded. the author also exposes the historical significance and limitations of these ideas, and also tries to reflect some problems of educational ideas of the western nationalism under the background of globalization

    第五部分是對西方民族主義教育思想的省察,先對西方民族主義教育思想的各種形態做了評析和審思,然後總結了西方民族主義教育思想的演變規律,並揭示了其歷史意義和局限性,還嘗試著思考了全球化背景下西方民族主義教育思想的若干問題。
  4. As the values of wave factors in period of reoccurrence were deduced for many significant propagating direction in the yangtse river estuary, the wave reflection - refraction modeling is employed in terms of the equations with the slowly varying topography, and the influence on the effects of the channel and shoaling is included in this model. at the same times, the effects of the bottom friction and wave breaking are also considered, but the local wind field and background flow are ignored

  5. Abstract : the reflective characteristics of sea and sky background radiation, which have important effect on the infrared signature from flight vehicle above sea, are studied in the paper. the statistical distribution of wave facet directions is discussed, the effects of randomly riging and falling sea wave on the sea surface radiation and on the sun light reflection are also discussed. calculation methods of irradiance from sea surface radiation and reflected sun light on observation point are derived in the paper. finally a computation example is given, which shows the sea and sky background radiation has important effect on infrared characteristic especially in the front area of a flight vehicle

    文摘:研究了對近海飛行體的紅外特性有重要影響的海空背景輻射的反射特性.討論了波浪面起伏隨機規律,隨機起伏對海面自身輻射及對陽光反射的影響,推演了此種隨機起伏波浪面的自身輻射及反射的陽光在觀測點形成的輻照度的計算方法.給出的算例結果表明,海空背景對飛行體的紅外特性尤其對其前半球的紅外特性有重要的意義
