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

A novel method of electrostatic suspension was developed. this article briefly discusses the basic concept, schematic setup and optronic feedback system of the electrostatic suspension. when taking an aluminum plate and a compact disc ( cd ) as the suspended objects respectively, it is measured the electrostatic forces acting on the objects under different electrode voltages and different electrode - object gaps. the experimental results show that the electrostatic forces are sufficient to levitate both of the suspended objects, namely the electrostatic suspension method is practically feasible. compared to the conventional magnetic suspension, the significant characteristic of the electrostatic suspension is that it is capable of suspending most of the conductive and / or nonconductive, magnetic and / or nonmagnetic objects. therefore, this method can be widely applied to realize the electrostatic suspension and non - contact manipulation of the precision objects
本文提出光電反饋式靜電懸浮的新方法，簡要討論靜電懸浮的原理、裝置及其光電反饋控制過程.採用鋁片和cd光盤作為懸浮體，測定了不同靜電電壓和不同懸浮間距時的靜電懸浮力，揭示了它們之間的相互關系.結果顯示這兩種懸浮體均可獲得足夠的靜電懸浮力，證明了靜電懸浮的可行性.靜電懸浮方法的顯著特點是既適用於導電體與非導電體的懸浮，又適用於磁性體與非磁性體的懸浮，克服了傳統磁懸浮技術僅適用於磁性體的局限性，可廣泛應用於精
