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。Other forces glacially silent and immovable, have prevented action.
所有其它的努力全都是冷若冰河的沉默和無動於衷，它們阻撓了一切行動。The stones are designed to generate as much frictional resistance as possible - like sand scattered on an icy pavement - and so reduce the speed of a skidding car quickly and effectively
砂石用以產生盡可能多的摩擦阻力-類似於砂石被撒在一條被冰覆蓋的路面上-如此一來就有效地緩解了一輛打滑賽車的速度。Freezing is a general phenomenon in the cold area. ice flood is a rise of water when ice is hindered in river course
冰凍是寒冷地區普遍存在的一種自然現象，而凌汛則是河道里的冰凌對水流的阻力作用而引起的一種漲水現象。Ice dam, ice cover and ice jam, which are farmed by stack, jammed and collective ice, can increase river resistance and water stage, resulting in flood, construction damage and navigation problems
冰塊堆積，堵塞和聚集形成的冰壩、冰蓋和冰塞會導致河道阻力增加，致使上游水位上漲，並可能造成冰期洪水，建築物破壞，航運不暢等危害。In the 1950s, a group of far - sighted people from the british business community overcame one obstacle after another, and made the famous ice - breaking trip to china, thus starting business exchanges with the newly - founded people ' s republic
上個世紀50年代，英國工商界一些有識之士沖破重重阻力，進行了著名的「破冰之旅」 ，開啟了同新中國的經貿往來。If they had instead found crystalline rock, like that underlying most continental ice sheets, including east antarctica ' s, they would have concluded that the greater friction of that material had been inhibiting ice motion
反之，若冰原底下是晶狀巖石，如同南極洲東部及多數大陸冰原的情況，可能就會因摩擦力較大而阻止積冰移動。Young people is his attempt to a teen drama and looking at it now, it harks back to a more innocent and cornball age
