水凝霜 的英文怎麼說
中文拼音 [shuǐníngshuāng]
水凝霜
英文
blush-
When snow crystals strike supercooled droplets, the droplets will immediately freeze onto them. this process, called riming, forms soft particles known as snow pellets or grains. in temperate zones, the melting of snow pellets provides much of the rainfall from cumulus clouds
每當雪晶碰到過冷的水點時，它們會立刻凝固在一起，形成的軟粒子便是雪小球，而整個過程被稱為"蒙霜" ;在溫和的區域里After this season of congealed dampness came a spell of dry frost, when strange birds from behind the north pole began to arrive silently on the upland of flintcomb - ash ; gaunt spectral creatures with tragical eyes - eyes which had witnessed scenes of cataclysmal horror in inaccessible polar regions of a magnitude such as no human being had ever conceived, in curdling temperatures that no man could endure ; which had beheld the crash of icebergs and the slide of snow hills by the shooting light of the aurora ; been half blinded by the whirl of colossal storms and terraqueous distortions ; and retained the expression of feature that such scenes had engendered
潮氣結為霧淞的季節過去了，接著而來的是一段乾燥的霜凍時期，北極後面一些奇怪的鳥兒開始悄悄地飛到燧石山的高地上來這些骨瘦如柴的鬼怪似的鳥兒，長著悲傷的眼睛，在人類無法想象其廣袤寥廓的人跡罕至的極地，在人類無法忍受的凝固血液的氣溫里，這種眼睛曾經目睹過災難性地質變遷的恐怖在黎明女神播灑出來的光明裡，親眼看到過冰山的崩裂，雪山的滑動在巨大的暴風雪和海水陸地的巨變所引起的漩流中，它們的眼睛被弄得瞎了一半在它們的眼睛里，至今還保留著當時看到這種場面的表情特點。During winter nights and under clear skies, the ground surface is cooled rapidly by radiating heat off to space. the air temperature near the ground will also fall and when the grass temperature drops below zero degrees celsius, hoar frost will form by direct sublimation of water vapour onto the grass surface
在冬天的晚上，如果天氣晴朗，地面的熱量會透過輻射快速散失，貼近地面的空氣也同時降溫，當草面溫度降到攝氏零度以下時，空氣里的水蒸氣便會在草面凝華成為白茫茫的霜。The numerical simulation accords with detective values in summing up it may be stated that we must keep the building wall dryness in order to produce a good heat performance, therefore, a air insulation is built in the high temperature layer and a air layer is built to eliminate moisture and exsuction damp in the low temperature layer,
本文指出，為了創造出熱功能優良的建築墻體，必須使建築墻體永遠保持乾燥狀態。因此，為使墻體長期保持良好的絕熱功能，必須在高溫側設置隔汽層，在低溫側設置排濕和吸潮的空氣層並及時排除空氣間層的凝結水及霜。How different had this scene looked when i viewed it laid out beneath the iron sky of winter, stiffened in frost, shrouded with snow ! - when mists as chill as death wandered to the impulse of east winds along those purple peaks, and rolled down ing and holm till they blended with the frozen fog of the beck
這景色與我在冬日鐵灰色的蒼穹下，冰霜封凍積雪覆蓋時看到的情景多麼不同呀！那時候，死一般冷的霧氣被東風驅趕著，飄過紫色的山峰，滾下草地與河灘，直至與溪流上凝結的水氣融為一體。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
