  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。
  2. Experimental process shows that variance of underwater distributary channel and declining rate of lake plane are closely related to moving intension of motive soleplate

    實驗過程顯示，水下分流河道的變遷與湖平面的下降速率及活動底板的運動強度密切相關。
  3. Secondly, a ship undocking process environmental forces testing plan is made by using the orthogonal design theory. measuring the environmental forces with different wind, wave and current combination from 0 ? to 90 ? and analyzing and processing the data are finished by using the analysis of variance method. comparing the experimental results with the results calculated using the ocimf method, the reliability of using the ocimf method is testified

    二、利用正交設計方法，制定了船舶出塢過程環境載荷測量方案，完成了船舶在出塢過程中從90到0過程中在不同風、浪、流組合下的環境外力測試和分析處理，利用級差分析方法，重點分析了風、浪、流以及方向對船舶出塢的影響程度大小，並把試驗結果和ocimf方法計算結果作了比較分析，驗證了ocimf方法計算結果的可靠性。
  4. Part five concerns itself with data analysis and discussion, which falls into three steps : in the outset, the descriptive analysis is made to compare the scores of experimental group and control group. furthermore, one - way analysis of variance ( anova ) is made to identify whether the cognitive strategies exert a certain influence upon the achievements of post test, and then the results of employment of cognitive strategies in experimental group and control group are compared and analyzed to draw a conclusion ; finally, comparisons are conducted to analyze the differences of cognitive strategies between effective students and ineffective students
