Many studies had attempted to characterize chemical weathering process by focusing on geochemisty of river particulate and sediment. the sediment geochemistry may reflect and compare with the carbonates and silicates weathering degree by introducing the chemical index of alteration ( cia ) and new sediment index of variation ( siv ) and elemental molar abundance ratio of the sediment. the one main objective of this study would provide and compare the relative weathering intensities of silicates and carbonates with the different basins
2沉積物地球化學與化學風化進程和機械剝蝕率化學風化指數與化學風化率屬于表徵化學風化作用意義不同的函數,前者為相對概念反映流域巖石在原巖基礎上己發生淋溶作用的深度,主要受到了氣候因子的深刻影響(中國流域沉積物化學風化指數由北到南呈有規則的遞增序列,氣候因子對風化進程的影響掩蓋了巖性的巨大差異) ,而化學風化率含義是指單位流域面積巖石風化淋溶產生的離子絕對總量。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,根據不同覆冰絕緣子正、負極性下的閃絡試驗結果,得出負極性電弧金屬陰極的強電子發射能力造成了單片瓷、玻璃絕緣子及被冰凌橋接的合成絕緣子有較低負極性冰閃電壓;正極性電弧金屬陽極側產生高電阻區所處位置的差異使得瓷和玻璃絕緣子串具有明顯的極性效應;覆冰較少時,合成絕緣子表面出現數量較多的非極性電弧使合成絕緣子無極性效應。利用覆冰期內平均閃絡電壓的試驗方法,對不同材質和結構的絕緣子在覆冰、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,直流平均閃絡電壓隨著海拔的升高、覆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、覆冰量、覆冰狀態、污穢度等有關。And the influence of water condition to growth and yield of crops were discussed briefly. then based on the meteorological data, yield data, drought and flood data of jiangsu province from 1961 to 2000, the water profit and loss of every ten days in the growing period of crops was calculated on the foundation of the water balance formula in every agriculture climate district. the disaster index of drought and flood was confirmed and calculated
根據江蘇省近40餘年的氣象資料、產量資料和旱澇災害資料,分農業氣候區利用農田水分平衡方程計算了不同作物逐旬水分盈虧量,確定了旱澇災害指數,並用多元積分回歸方法分析了降水對棉花和小麥產量的定量影響,得出作物生長期內逐旬水分敏感指數。It has the basic features of strong market competition, obvious economic benefits, large production scale and high industrial specialization. the development of characteristic resource in a region is based on the advantages of local resources - both naturally and anthropogenicaly. therefore, its target is to explore the advantageous local resources to produce high quality agricultural goods to meet the demands of markets and society for the return of high profits
