Under the different freezing - thawing cycle circumstance, three factors of water binder ratio, air content and mineral admixture are analyzed by using the method of orthogonal table. the test results show that the chief influencing factor is the water binder ratio in water freezing - thawing cycle circumstance, and in salt freezing - thawing cycle circumstance is the air content. this could illustrate that entraining air into concrete can improve the frost resistance of concrete effectively in salt freezing - thawing cycle
分析了在純水和3 . 5 % nacl溶液中受凍后，水膠比、含氣量和摻合料對混凝土飽和系數及變化速率的影響規律，試驗結果表明水膠比對混凝土水凍時的飽和系數及變化速率影響顯著，而鹽凍情況下含氣量則是主要影響因素，說明引氣能顯著提高混凝土的抗鹽凍性能。 -

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。 -
