  1. The main work and conclusion for this paper is as following : according to the flashover test results of several kinds of iced insulators under positive voltage and negative voltage, this paper obtained : for the single porcelain insulator, the single glass insulator and the composite insulator bridged completely by icicle, the metal cathode ' s strong ability of emission electron is the primary reason that results in the lower negative flashover voltage ; the position difference of the high resistance district in method anode side results in that porcelain insulator cluster and glass insulator cluster have an evident effect of polarity ; when less ice and no icicle at the brim of the sheds, due to numerous non - polar arcs on the composite surface, the effects of polarity of composite insulator was lost using the test method of the average flashover voltage in the freezing period, dc flashover performances were investigated of several insulators with some typical structures and different material

    本文的主要工作和結論如下:在人工氣候室內,根據不同冰絕緣子正、負性下的閃絡試驗結果,得出負弧金屬陰的強子發射能力造成了單片瓷、玻璃絕緣子及冰凌橋接的合成絕緣子有較低負性冰閃壓;正弧金屬陽側產生高阻區所處位置的差異使得瓷和玻璃絕緣子串具有明顯的性效應;冰較少時,合成絕緣子表面出現數量較多的非弧使合成絕緣子無性效應。利用冰期內平均閃絡壓的試驗方法,對不同材質和結構的絕緣子在冰、低氣壓和污穢共存環境中的直流閃絡特性進行了研究。試驗結果表明,直流平均閃絡壓隨著海拔的升高、冰量的增加以及污穢度的增加而降低,且其特徵指數與絕緣子結構、冰量、冰狀態、污穢度等有關。
  2. This technique is mainly involved two steps : 1 ) vegetation effects correction : we used ndvi ( normalized difference vegetation index ) derived from tm and avhrr measurements for spatial and temporal variations of vegetation covers at different scales

    但由於磁波與地表相互作用的復雜性,雷達後向散射系數除受地表介常數(土壤水分)影響外,還受到地表粗糙度、土壤類型、植蓋以及雷達入射角、頻率、化等多種因素的影響。
