Topics include : molecular and turbulent diffusion, boundary layers, dissolution, phase partitioning, bed - water exchange, air - water exchange, settling and coagulation, buoyancy - driven flows, and stratification in lakes
探討課題計有:分子和紊流擴散、邊界分層、溶解、相之間的分割、底床與水間的交換作用、空氣與水間的交換作用、沉降和混凝、浮力流以及湖泊分層作用。 -
The complicated behavior and multiple states of indoor air convection are mainly related to the multiple physical processes, such as the thermal buoyancy, the solutal buoyancy and the mechanical ventilation
室內空氣對流行為的復雜性與狀態的多樣性通常是多種物理過程相互作用的結果，如離散熱源的熱浮升力、離散污染源的濃度浮升力及機械通風等。 -
In this article, simulations of air distribution in the vav air - conditioned office are carried out in the cases of different air - supplying diffusers including slot diffuser, sqaure grille, bar grille and square diffuser to supply air, the standard three - dimensional k - ? two - equation turbulence model with correctional item of buoyancy effect and simple algorithm are adopted, and wall function method is used to handle boundary conditions
本文採用經過浮升力項修正的-兩方程模型和simple演算法，應用壁面函數法處理邊界條件，對利用包括條縫風口、方型百葉風口、長條型百葉風口和方型散流器不同型式送風口送風的變風量空調房間內的氣流組織進行了模擬。 -
There are many advantages to heat by air condition system, but there are also many problems. the air distribution of air condition room is often designed according to the summer outdoor parameters. thus, in winter, the hot air will arise with the influence of buoyancy, which result in the decline of vertical temperature gradient and produce a successive of problems
空調送風供暖有著很多的優點，但也出現了很多問題，由於空調房間的氣流組織一般是以夏季工況為設計工況，在冬季由於送風熱氣流在浮升力作用下上升，引起垂直溫度梯度的增加，並產生一系列的問題，致使空調房間冬季室內熱舒適性較差、能源利用效率較低。 -
From the measured mass, the volume can be determined with a knowledge of water density and corrections for air buoyancy and thermal expansion of the vessel. the volumetric method requires a standard ( calibrated ) volumetric measure
重量分析測定法測定一個測試量器所載或所出的水的質量。從量得的質量，加上水的密度，空氣浮力及容器的熱力膨脹修正，便可測定容量。 -
Qarticipants can experiedce the gravity - free feeling brought by the neutral buoyancy, hear the beautiful sound of the air bubbles from their own breathing, see all kinds of fancy corals and swim side by side with the tropical fishes in various colors
參加該活動的遊客可親身體驗到海底的中性浮力所帶來的無負重的感覺，聆聽到自己呼出氣泡的悅耳響聲，觀賞到海底種種奇特的珊瑚和五彩斑斕的熱帶魚。 -
As for passepartout, his face was as red as the sun s disc when it sets in the mist, and he laboriously inhaled the biting air. with his natural buoyancy of spirits, he began to hope again
至於路路通，他的整個臉膛又圓又紅，活象傍晚沉浸在薄霧里的太陽他正喝著那刺骨的寒風，他又恢復了他那種固有的信心，蘇生了成功的希望。
