Adopting the actual county - grade database of land use firstly founded in china, combining with the comprehensive influential factors of land use change, using the correlative statistic software and the mathematic analytical methods ( principal component analysis, gray relating analysis, multivariate time series markov chain analysis, multivariate regression analysis, gm ( 1, 1 ) gray model, gray series gm ( 1, n ) model methods etc ), this paper analyses the dynamic change of land use and driving force in jiang ' an county qualitatively and quantitatively. the results indicate : 1 the land resource per capita and the area of single - land - use type in jiang ' an county are not prior to other places in yibing city or sichuan province. however, the terrain is dominant in choosing the way of land use

    本文採用全國首批建立的「縣級土地利用現狀數據庫」的基礎數據,結合影響土地利用變化的經濟、社會、環境等綜合因素,採用相關分析軟體( dps 、 spss )和數學分析方法(主成分分析、灰色關聯度分析、多元回歸分析、多元時空序列馬爾柯夫鏈分析、 gm ( 1 , 1 )預測模型分析、灰色序列gm ( 1 , n )模型分析等方法) ,對江安縣土地利用變化及其驅動力進行定性、定量研究,研究結果表明: 1江安縣人均總的土地資源數量和單一土地利用類型的數量在宜賓或四川省區域內均無優勢;地形對土地利用方式的選擇起著主導作用;土地利用變化的總趨勢是:耕地、林地、交通用地和水域面積不斷減少,居民點及工礦用地和未利用地面積不斷增加;景觀多樣性指數呈現「 」趨勢。
  3. It sets up a evaluated system by analyzing groundwater chemical components, through studying pertinence in water chemical component and soil strength, it also puts forward that water chemical change can map soil strength variation under water - soil interaction. from the theory of the water - soil interaction on, the interrelation of city construction, the variation of groundwater condition and the soil structure strength is analyzed and that the measure of soil structure and the significance which is by the water - soil interaction is studied in this paper. at the same time, in the paper : the recourse of the soil structure strength is summarized ; the physical meaning of soil mini - scale structure is defined ; the measure of soil structure is classified ; the four basis forms of the water - soil interaction is induced ; the chemistry mechanism of the water - soil interaction is discussed

  7. The recursive criterion of transient current protection based on mallat wavelet transform is presented in order to meet the real - time demands. the reserch shows deficiency existed in the prevenient principle of transient current protection, so a new improved scheme of transient current protection is proposed. the characteristics of transient protection at different bus distribution capacitance is also analysed in this thesis. the study shows that operate of transient protection is correct when the bus distribution capacitance change. other conclusion include : the trip of transient protection must be locked when the power circuit breaker of transimission line operated, because the trip is incorrect at this time ; the features of transient current and it ' s energy is different between the fault and thunder over - voltage in transimission line, and them can be identified ; the ratio of high frequency component of current in serise capaciters compensation line, svc and hvdc system is far little than fault transient current, so all of them do not affect the working of trasient current protection

    應用功率譜估計方法討論了故障高頻暫態噪聲信號在頻率軸上的分佈情況,利用功率譜分析結果實現的非參數化系統辨識方法研究了母線分佈電容對電流高頻暫態信號的衰減特性。論文的後半部分(第五,六,七章)著重分析了現有基於故障電流的暫態保護原理和判據存在的問題,提出了新的實現方案,並討論了暫態電流保護的運行性能。利用多分辨分析和小波分解快速演算法構成的遞推暫態保護判據,可以準確區分故障線路和非故障線路,實現超高速暫態電流保護,計算更為簡單方便,計算速度更快。
