Test results indicated : with the hoist of altitude, the increase of ice amount and the rise of pollutant, the average flashover voltage reduced. the character exponent generally depends on the insulator profile, ice amount, ice state and pollution severity etc. by means of a high - speed camera, a data acquisition system and high voltage test facilities, a series of the flashover processes on ice surfaces were record. the experimental results form this study and the subsequent theoretical analyses suggested : the thermal ionization of the air in front of an arc root resulted in arc movement ; the electrostatic force had an auxiliary effect of impelling arc propagation ; the electrical
通過對攝像機、數據採集系統及高壓試驗裝置記錄覆冰絕緣子表面閃絡電弧的發展過程的試驗結果進行理論分析得出：弧根周圍空氣的熱電離導致了電弧的發展，靜電場力對電弧的發展起到了加速作用，電擊穿僅發生在閃絡最終的跳躍階段；通過測量閃絡過程中的放電電壓、泄漏電流、閃絡時間、覆冰水電導率、電弧長度及電弧半徑等參數，得到了不同階段電弧（電弧起弧階段、電弧發展階段及完全閃絡）的發展速度、臨界電弧長度均隨覆冰水電導率的增加而減小。In term of soil water coefficient of variation, the soil water profile in 0 - 100cm can be divided into 3 layers, i. e., hypoactive layer, hypoactive layer and correspondingly stable layer. these soil water layers varied along with soil water consumption seasons alternating
就綠地類型而言，活躍與次活躍層總深度：本特草坪高羊茅草坪泡桐綠地；就季節變化而言，弱耗水期活躍與次活躍層淺，強耗水期深，微耗水期較深。To the large - scale atmosphere, we separate the terms of the horizontal vorticity converting into the vertical vorticity, which considered as the baroclinic terms, from the terms that not including horizontal vorticity by the rules of the p coordinate transforming to the z coordinate in the traditional vorticity equation, and carry out the scale analysis, and then conclude that the baroclinic terms are able to reach the same magnitude grade as the partial derivative of the vertical vorticity to time when it takes place the large scale precipitation in the summer monsoon period in china. by analyzing the game reanalysis data from april to august in 1998 in the region of chinese continent, we found that the baroclinic terms is important to the large - scale cyclone developing above the 600hpa, and the magnitude changing of the baroclinic terms is nearly in - phase as the monsoon movement, so which imply exactly that the magnitude changing of the baroclinic terms is the one of the natural characters of the summer monsoon evolution and equivalent to the movement rule of the subtropical high of the western pacific
在p坐標垂直渦度方程中，利用p坐標向z坐標轉換的公式將水平渦度向垂直渦度轉化的所有項分離出來，這些項具有明顯的斜壓特徵，對其進行尺度分析后，得出在可以忽略潛熱釋放對渦度影響的對流層中、高層，此轉化項是大尺度斜壓渦度發展的重要項。通過對1998年48月的game再分析資料進行實際計算也發現，轉化項在東亞夏季風上升支的600hpa及以上層次對垂直渦度的局地變化貢獻很大，不能忽略。同時發現水平渦度向垂直渦度的轉化在南海季風爆發時和江淮梅雨入梅及發展過程中均有指示性意義，在南海季風爆發以後，在中國東南部地區，轉化項的大小與夏季風的活躍和中斷等活動有著幾乎一致的變化規律，這從側面也指出了，此轉化項的變化是夏季風演變所具有的本質特徵，並且它反映出了西太平洋副高在中國大陸的活動情況。But it will affect the airflow organization with the cooled airflow drops. also, it studies the impact of solar radiation on displacement ventilation and cooled ceiling system. horizontal warm areas lowers the height of thermocline and is unfavorable to displacement ventilation system ; vertical hot surfaces will destroy the thermal stratification
水平熱表面的存在，會使系統的溫躍層高度降低，對置換通風系統會有負面影響，為了減小水平熱表面的影響，對于地板材料應該選擇對長波輻射吸收較低的物質;垂直局部熱表面的存在會破壞置換通風系統溫度分層的特性，使垂直方向溫度變化減小。The daily change law of air ion is : the density of air ion in morning is the highest, it falls at noon or in the afternoon. while it raises again in the dusk.
