Abstract : in the internal circulating fluidized bed, there exist the moving zone, fluidizing zone and heat transferring zone with different fluidized air velocities. the convection heat transfer coefficient of immersed tube in the heat transferring zone is impacted by the velocity of the moving zone nearby and its data and change trend are obviously different with those of the common bubbling bed. the maximum heat transfer coefficient is evidently higher than that of the bubbling bed. as the bed materials have not been fluidized in the heat transfer zone, the coefficient has increased highly. the curve of that changes gently, feasilble to control the combustion intensity in the fluidizing zone
文摘:垃圾焚燒系統中，內旋流流化床存在不同布風速度的移動區、流動區和換熱區，處于換熱區的埋管的對流換熱系數受附近流動區氣流參數的影響，其變化趨勢及數值大小與普通鼓泡型流化床之間有明顯不同：最大的對流換熱系數明顯高於鼓泡床；換熱區尚未流化時，對流換熱系數已經大幅提高；整條換熱曲線的變化比較平緩，易於流化床濃相床內換熱。 -
Aimed at the practical performance of soft clay, the static equilibrium equations taking consideration of effect of mass change, with the introduction of soil configuration, soil convection formula and mass conservation theory in soil, are derived, which reveal the phenomenon of coupling of total stress and seepage in equilibrium equations. then, some advisable experimental means are explored to determine the effect of mass change during consolidation. objective stress and strain should be used in large strain analysis
針對軟粘土大變形固結的實際性狀，文中引入了土體構形的概念，土體傳運公式和土體質量守恆定律，並由此導出了考慮變質量效應的大變形固結靜力平衡方程，揭示了平衡方程中存在的總應力與滲流相互耦合的效應，並考慮了固液兩相的可壓縮性，進一步探索了測試變質量效應的試驗方法。 -
One reason is the change of interior convection zone with spectral type produce the phenomena ; another reason is the differential rotation of f type stars exist a upper limit
這一拐點的出現可能是f型主序星的對流區的變化影響形成的，也可能是f型主序星在f5附近存在較差自轉的上限形成的。
