空隙冰 的英文怎麼說
中文拼音 [kōngxìbīng]
空隙冰
英文
interstitial ice-
Electrical field stress at the icicle tips is even stronger. at these areas, if the electric field across air gaps is high enough, corona discharges are initiated. this can lead to the development of local arcs across the air gaps causing a substantial increase in leakage current and a concomitant melting of ice
空氣間隙的存在使覆冰絕緣子表面的電場分佈發生了明顯畸變,間隙上承受了非常高的電壓,這使得冰凌尖端的電場變得相當強,一旦電場達到了電暈的起始電場,局部放電就在這一區域發生,進而產生局部電弧並逐漸發展成整串的閃絡,泄漏電流迅速增大,同時伴隨著冰的融化。The existence of air gaps will inevitably distort strongly electrical field distribution and cause to a significant voltage drop across the gap, which causes severely non - uniform electrical field near the icicle top
運行和試驗研究表明,絕緣子串在運行電壓或試驗電壓下覆冰時其高壓端總是存在空氣間隙。By applying related theory of gas discharge and mathematical statistics, this paper more in - depth and systemic study the influence of the length of air gap, ice state, water conductivity and air pressure on the inception corona and pulse discharge characteristics, included the discharge frequency, discharge amplitude and time interval
根據試驗結果,用氣體放電和數理統計方法,分析了覆冰水電導率、冰的狀態(乾冰和濕冰) 、空氣間隙長度、氣壓和施加電壓等參數的變化對間隙模型的起始放電電壓、脈沖放電特性、放電頻率、放電幅值和時間間隔等的影響。Abstract : the paper presents a theoretical study on the thermal conductivity of frost formation on cooled flat plate under forced convection. taking the porous meditum as a physical model of frost layer, according to the theories of heat and mass transfer, the formula on heat conductivty of frost formation is derived
文摘:研究水蒸汽凝華結霜過程在冷壁上形成的霜層的導熱系數,依據隨機管子多孔介質霜層模型,假設霜層是由孔隙空間與冰晶骨架構成的多孔介質,其中孔隙空間由隨機毛細管及連接管子的接頭形成,濕空氣中的水蒸汽在霜層的孔隙空間中擴散輸運並凝華結霜,根據傳熱傳質學理論,導出霜層導熱系數關系式。Using both hands, she clawed a larger hole. it was disappointingly narrow. the sun ' s heat had warmed the dark post, but not enough. the slot between the hard ice and the wood was too narrow for her body. if it proved too narrow for her head as well, she would die
雙手並用,她抓大了洞,失望的是洞太窄了。太陽的熱能使黑色的柱子有了溫度,只可惜溫度不夠,堅硬的冰層和木頭之間的空隙不夠讓她爬上去。假如連頭也伸不出去的話,她只有死路一條了。分享友人
