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 inception voltage decrease with reduction of air pressure ( increase of altitude )

為制定中國老年男性紅細胞壓積參考值的統一標準提供科學依據，收集了中國各地用溫氏法測定的健康老年男性紅細胞壓積參考值，並對其與地理因素的關系進行了研究，發現海拔高度是影響老年男性紅細胞壓積參考值最主要的因素，隨著海拔高度的逐漸增大，老年男性紅細胞壓積參考值也在逐漸增大，相關性很顯著.用逐步回歸分析的方法推導出了一個回歸方程.如果知道了中國某地的地理因素，就可以用回歸方程估算這個地區的老年男性紅細胞壓積參考值.依據老年男性紅細胞壓積參考值與地理因素的依賴關系，把中國分為青藏區、西南區、西北區、東南區、華北區、東北區等6個區The study results show that the minimum ac flashover voltage decreases with the increase of the ice amount accreted on the insulator surface by an exponential law, and the down - trend of the minimum ac flashover voltage will slow gradually with the bridging of the shed of the insulators by icicles, both the average saturated ice amount and the special exponent m of effect of ice amount for different insulators depend on the radius of shed and the air - gaps of the sheds of the insulators, and that the ac ice flashover voltage decrease with the decrease pressure ratio p / p0 ( rise of the altitude ) by power - law for different esdd and icing - states when the altitude is from 4000m to 5500m. the special exponent n, which show the effects of altitude on the flashover voltage, is various with the type of insulator, icing - states and the surface status of iced insulator etc., and that the minimum ac flashover voltage of iced insulators decreases by power - law with esdd or the freezing water conductivity for different ice amount and atmospheric
研究結果表明：在不同海拔高度和等值鹽密esdd下，絕緣子的最低交流冰閃電壓均隨覆冰量的增加而呈指數規律降低；當覆冰量增加到一定程度后，最低交流冰閃電壓隨覆冰量增加而降低的趨勢趨于飽和；不同絕緣子串的平均飽和覆冰量及閃絡電壓的覆冰量影響特徵指數m均與絕緣子的盤徑和傘距等因素有關；在海拔4000 5500m之間，不同等值鹽密esdd和覆冰狀態下，絕緣子的交流冰閃電壓隨海拔高度的增加（氣壓的降低）與p / p0呈乘冪關系降低，氣壓影響特徵指數n與絕緣子類型、覆冰類型、覆冰表面狀況等因素有關；當覆冰量和氣壓一定時，絕緣子的最低冰閃電壓均隨著等值鹽密（ esdd ）或覆冰水電導率的增加而呈乘冪關系降低，並逐漸趨于飽和。The month average and the year average water vapor press in chongqing both show that : the water vapor press decreases with the increasing of sea level elevation ; the water vapor press values in north - west and middle hill areas are middle and high ; the water vapor press values in north - east and south - east mountain areas are relatively low. the sea level elevation in north - east and south - east mountain areas of chongqing is higher, especially the north - east mountains are more rugged than the north - west mountains, and the decreasing of water vapor press with the increasing of sea level elevation is more distinct, so the lowest value often appears in the north - east mountains not in the north - west mountains. the seasonal change of water vapor press in chongqing is also distinct : the values of water vapor press are low mostly in winter, and the high values are relatively less ; the values of water vapor press are middle and high mostly in summer, and the low values are relatively less, the values in spring and autumn are between them
重慶市全年各月月平均和年平均水汽壓都表現出：隨著海拔高度的增加，水汽壓逐漸減小；西北部和中部的丘陵低山地區一般為水汽壓的中高值區；東北部與東南部的山地地區的水汽壓則相對較小重慶市東北東南山地地區海拔高度較高，尤其是東北山區的山地較東南山區的起伏更大，水汽壓隨海拔高度的減小更加明顯，因此各月的最小值往往出現在東北山區而非東南山區重慶市水汽壓的季節變化也很明顯：冬季水汽壓多為小值，大值較少；而夏季多為中、大值，小值較少；春秋季則介於兩者之間。The mountain water vapor press decreases as a e index with the increasing of sea level elevation ; the constant item and the once items of longitude and latitude are important to the spatial distribution of water vapor press ; the twice items of longitude and latitude are less important to the spatial distribution of water vapor press
山區水汽壓隨著海拔高度的增加呈e指數減小；經度和緯度的常數項和一次項對水汽壓空間分佈的影響比較大，經度和緯度的二次項對水汽壓空間分佈的影響比較小。分享友人
