heat transfer surface area 中文意思是什麼
heat transfer surface area
解釋
傳熱面積-
A transfer model is established, which can be used to study the interaction between the land surface physical processes of inhomogeneous region and the structure of atmosphere boundary - layer over urban and rural terrains. the model has simulated surface heat flux, surface temperature, temperature profiles, height of mixture layer and so on. and the differences between urban area, suburban area and rural area have been compared. this model mainly depends on the parameters below : surface albedo, surface roughness coefficient, moisture available coefficient of soil, thermal capacity and thermal diffusion coefficient of errain, cloudage. the result shows that this model can simulate the structure and eigenvalues of atmosphere boundary layer and their changes in a day. parameters used in this model aim at beijing city, and the time is at the beginning of september. to other cities, or other time, the parameters should be adjusted accordingly. in addition, being adjusted, the model can also be used for other homogeneous and inhomogeneous terrains
模式主要依賴于以下參數和物理量：地面反照率下墊面粗糙度土壤的可含水量下墊面的熱容量和熱擴散系數雲量等參數。結果表明，本模式能合理地模擬不同地表熱量平衡地表氣溫混合層高度湍流交換系數湍流動能位溫廓線等，以及它們的日變化。該模式所取參數主要針對北京市，時間為九月初，對于其他城市，參數應作相應的調整。 -
Although a variety of techniques, such as addition of surface area, swirl flow devices, vibration of heated surface, vibration of fluid, are applied to enhance heat transfer, major improvements in heat transfer capabilities have been held back because of the low thermal conductivity of conventional heat transfer fluids
隨著對熱交換設備換熱表面強化傳熱技術研究的深入，換熱工質的傳熱性能已成為影響熱交換設備高效緊湊性能的一個主要因素，低導熱系數的換熱工質已成為研究新一代高效冷卻技術的主要障礙。 -
In view of results obtained in the work, the commonly 共同 made assumption 假定 of equality 均等 of heat transfer coefficients for both the bundle and its additional surface may lead to certain 確定 errors 誤差 in heat transfer calculations and discrepancies between the calculated values of heating surfaces area and later operational needs of steam generator
在工作得到的結果，傳熱系數的做法為捆綁和它附加的表面在熱傳遞演算也許導致某些熱化表面的誤差值和蒸汽發電器之間的錯誤和差誤。 -
Roadbed construction on permafrost will give substantial disturb for the heat and mass transfer balance between the ground surface and atmosphere, usually, roadbed construction increases the amount of absorbed heat via vegetation removal, solar radiation and increased role of water activities in the adjoining area, then cause the local degradation of the permafrost underneath, as a result may lead to damage of the roadbed
多年凍土區道路的修築，改變了原來天然地表與外界的熱交換關系，通常由於地面植被的破壞、太陽輻射和水的影響，導致進入地層中的熱量增加，引起多年凍土區凍土的融化，從而導致路基面破壞。
