相平衡熱容
英文
heat capacity in phase equilibrium-
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。Heat capacity in phase equilibrium
相平衡熱容The membrane properties were found to be dependent upon the content of styrene. the membrane physic - chemical properties compare to nafion 117 except that their chemical stability has to be further improved to make them acceptable for practical use in the proton exchange membrane fuel cell. the proton transport through the membrane follows the " liquid - like " proton conductivity mechanism y and the water balance is important for the working condition of the fuel cell
對磺化膜的研究分析表明:膜的性能參數如離子交換容量、吸水率、水合系數、形體穩定性、導電性能、化學與熱穩定性等依賴于膜中苯乙烯含量,且接枝苯乙烯相互間的位阻效應對膜性能影響很大;膜的性能可與nafion膜相比較;質子在膜中的傳導遵循「似液體」質子傳導機理;電滲析與擴散作用使膜保持水平衡。This experiment include many contents, in a word, that is summer condition experiment, winter condition experiment > summer - winter transition condition experiment and winter - summer transition condition experiment, furthermore summer condition experiment still include flux changing experiment and winter condition experiment still include thermal balance experiment this article dealt with the data of the test, calculating out energy absorbing ( energy discharging ) of buried pipe in winter condition ( summer condition ), input power of heat pump x heat exchanging of piece buried pipe length x co - efficiency performance ? op ( energy efficiency rate ? er ) and average heat exchanging coefficient ; in additiont this article compares the inlet water temperature and outlet water temperature of underground the first layer and the second layer buried pipe when heat pump was running, the results are that the heat exchanging ability of the second layer buried pipe outgos the first layer buried pipe, and heat exchanging is more stable ; and still analyse earth temperature resuming in the transition season. the results are earth temperature resume fast in the first week when the heat pump runs off
本文測試內容相當多,概括地說就是四個工況的測試,即夏季製冷工況的測試、冬季供熱工況的測試、夏?冬過渡季測試和冬?夏過渡季測試;另外在夏季工況的測試中還進行了變流量測試,在冬季工況的測試中還進行了熱平衡測試。本文對測試數據進行了處理,計算出了冬(夏)季工況埋管吸(放)熱量、熱泵空調器供熱量(製冷量) 、熱泵空調器輸入功率、埋管單位管長換熱量、供熱性能系數(製冷能效比)和平均傳熱系數等;另外,還比較了熱泵運行時地下一二層埋管進出水溫度變化情形,得出地下二層埋管換熱能力優于地下一層埋管,且換熱很穩定;並分析了過渡季地下一二層埋管溫度恢復情形,得出熱泵系統停機一周內地溫恢復特別快。The characteristics of this new cycle at different working conditions were calculated and analyzed carefully based on mass, heat, and phase equilibrium. besides, the characteristics of a traditional single - effect absorption refrigeration cycle under the same condition are also calculated for comparison
在理論上,本文依據新循環內部的熱平衡、質量平衡及相平衡,對循環進行了熱力分析,研究了變工況下循環的各種性能的變化情況,並深入分析了變化原因,結果發現,冷凝蒸發器中兩股流體的熱容量是否匹配是決定cop值的關鍵因素。In summary, whether making use of the thermodynamical equilibrium fluctuations or the non - equilibrium fluctuations, we find that the second order phase transition points lie in where the heat capacities approach infinite, rather than where r + r _ in the stationary black holes
摘要h由以上討論我們得到如下結論:無論是採用平衡漲落方法,還是採用非平衡漲落方法,穩態黑洞的二級相變點都位於熱容量無窮大的地方分享友人
