一個具有三維氫鍵超分子結構的金雞納霜生物堿衍生物的合成和晶體結構In that sort of half reverie which permits one to participate in an event and yet remain quite aloof, the little detail which was lacking began obscurely but insistently to coagulate, to assume a freakish, crystalline form, like the frost which gathers on the windowpane
這種迷迷糊糊的幻想狀態既允許一個人置身於一個事件之中又叫他保持冷漠,在這種狀態中那尚未可知的小小細節開始模糊而又執著地凝聚,形成怪異的晶體,像窗子上結的霜,那些霜樣的晶體顯得這么怪誕,這么徹底無拘無束,這么奇形怪狀,然而它們的命運卻要由最最嚴酷的自然法則操縱,而我心中產生的感情亦是一樣。Two faceted clear crystal small snails on a frosted crystal leaf
二在清楚水晶小蝸牛上雕琢平面在一片結霜的水晶葉子。Faceted clear crystal stallion ; frosted tail and mane ; raised front legs and upright position
在上雕琢平面的清楚水晶公馬;結霜的尾巴和鬃毛;被舉的前面腿和挺直位置。Set of two baby tortoises ; clear crystal faceted body with frosted crystal legs ; jet crystal eyes
套二隻幼崽草龜;清楚水晶在上雕琢平面的身體與結霜的水晶腿;噴氣機水晶眼睛。If the cold plate temperature is higher than a certain critical value, for instance, - 12 c under our observed experimental conditions, the higher the air relative humidity is, the bigger the water droplets concreting on the cold plate, and the later the water droplets froze. however, if the cold plate temperature is lower than a certain critical value, the influence of air relative humidity on the frozen time of water droplets was not observed. if the cold plate temperature is higher than a certain critical value, for example, - 20 c under our observed experimental conditions, frost deposition is through condensation, or condensation frosting
結果表明,冷壁面溫度越低,水珠凍結時間越短,且凍結的冰珠越小;當冷壁面溫度高於某一臨界值,譬如,在我們給定的實驗條件下, - 12 c時,空氣相對濕度越大,冷壁面上凝結的水珠越大,水珠凍結越晚,但當冷壁面溫度較低時,幾乎觀察不到空氣相對濕度對水珠凍結時間的影響;冷壁面溫度高於某一臨界值,譬如,在我們給定的實驗條件下, - 20 c時,發生凝結成霜,冷麵溫度低於這一臨界值時,發生凝華成霜;隨著實驗工況的不同,觀察到的霜晶呈現八種不同的形態。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。The frosting of air cooler is owed to the joint effects of surface growth of frost and deposition of floating ice crystal ; 2
結霜是表面生長與懸浮冰晶沉積等共同作用的結果。分享友人
