frost in the air
解釋
氣霜-
It was a fine dry night, frost in the air.
那是個明朗無霧的夜，霜氣凜人。 -
Under the different freezing - thawing cycle circumstance, three factors of water binder ratio, air content and mineral admixture are analyzed by using the method of orthogonal table. the test results show that the chief influencing factor is the water binder ratio in water freezing - thawing cycle circumstance, and in salt freezing - thawing cycle circumstance is the air content. this could illustrate that entraining air into concrete can improve the frost resistance of concrete effectively in salt freezing - thawing cycle
分析了在純水和3 . 5 % nacl溶液中受凍后，水膠比、含氣量和摻合料對混凝土飽和系數及變化速率的影響規律，試驗結果表明水膠比對混凝土水凍時的飽和系數及變化速率影響顯著，而鹽凍情況下含氣量則是主要影響因素，說明引氣能顯著提高混凝土的抗鹽凍性能。 -
On the first day, when, getting up early in the morning, he came out of the shed into the dawn, and saw the cupolas and the crosses of the new monastery of the virgin, all still in darkness, saw the hoar frost on the long grass, saw the slopes of the sparrow hills and the wood - clad banks of the encircling river vanishing into the purple distance, when he felt the contact of the fresh air and heard the sounds of the rooks crying out of moscow across the fields, and when flashes of light suddenly gleamed out of the east and the suns rim floated triumphantly up from behind a cloud, and cupolas and crosses and hoar frost and the horizon and the river were all sparkling in the glad light, pierre felt a new feeling of joy and vigour in life such as he had never experienced before
第一天，他一大早就起了床，走出棚子，頭一眼就看見新聖母修道院開始還發暗的圓屋頂和十字架，看見覆蓋著塵土的草上的寒露，看見麻雀山的丘陵，看見隱沒在淡紫色遠方的，長滿了樹木的，蜿蜒著的河岸，他覺得空氣清新，沁人肺腑，可以聽到從莫斯科飛越田野的烏鴉的啼叫聲，一會兒，在東方天際邊，突然噴射出萬道霞光，一輪紅日從雲層里漸漸顯露出來。於是，圓屋頂，十字架露水遠方和那條小河所有這一切都在陽光下閃爍，這時，皮埃爾感覺到一種從來都沒有經歷過的，全新的，生活的喜悅和力量。 -
Now and again a hole gave the first sledge a jolt ; the next was jolted in just the same way, and the next, and the sledges followed one another, rudely breaking the iron - bound stillness. a hares track, a lot of tracks ! natashas voice rang out in the frost - bound air
前面的雪橇在行駛時碰到了一個坑窪，顛簸了一兩下，後面的幾輛雪橇也同樣地碰到了坑窪，這幾輛雪橇莽莽撞撞地打破禁錮著的寂靜，開始拉開距離向前駛去。 -
There was frost on the stubble fields, faint wood smoke in the air, mingled with the odors of ripe apples, drying corn shocks, crushed walnut hulls
收割后的麥田已披上寒霜，周圍飄散著淡淡的炊煙，夾雜著熟蘋果、干玉米堆和碎胡桃殼的香味。 -
In this paper, the contrast experiments and theoretical researches on frosting and defrosting on low - energy surface and common metal surface are carried out simultaneously. low - energy surface restrains the frosting of air cooler, and the adhesion work of unit - area frost on low - energy surface is smaller than that on common metal surface, so pneumatic defrosting becomes easier
本文還對低能表面與普通金屬表面的結霜、除霜進行了對比實驗和理論研究：低能表面不僅能有效地抑制蒸發器的結霜，而且單位面積霜層粘附功w _ ~ *比普通令屬壁面小，因而氣動除霜更容易。 -
Through manipulating the air content of mixture to control concrete frost resistance is the universal method in projects, but the study on the effect of concrete pore structure change after air entraining to the concrete frost resistance and impermeability is few, the study on the effect of mineral additive to concrete pore structure and durability is even fewer, so carry on this aspect research has significant meaning
通過控制拌合物的含氣量來控制混凝土的抗凍融性，是目前工程中普遍採用的方法，但引氣后混凝土的孔結構變化及其對抗凍、抗滲等耐久性的影響研究較少，而無機鹽類外加劑對混凝土孔結構及其耐久性影響的研究更少，因此開展這方面的研究具有重要意義。 -
There is a touch of frost in the air.
空氣中略有寒意。 -
Since frosting is inevitable so long as some physical factors are satisfied, it will enlarge the resistance of airflow, cut down the airflow rate of air cooler and reduce the coefficient of heat transfer. in order to keep the refrigeration system run smoothly, frost must be removed
結霜只要滿足一定的物理條件就是不可避免的，霜層增厚增加了空氣的流動阻力，冷風機盤管流量減少，同時霜層增厚也會導致傳熱系數下降，因此為保持系統高效運行，除霜是必須的。 -
In the northern area of our country, the climate is so cold, that the frost damage is very serious, especially in the northeast. induced air into the concrete is the most efficient way to improve the behavior of the frost resistance. therefore, studying on the reinforcement corrosion of the air - entrained concrete has important significance
我國北方地區氣候寒冷，凍害比較嚴重，東北地區尤甚，而引氣是提高混凝土抗凍性的最有效措施，因此研究引氣混凝土的抗鋼筋銹蝕性能有重要的現實意義和明顯的經濟效益。
