  1. From the analyse of the process controlling equations, the dimensionless parameters which affect the nu number and the sh number in cfb were obtained, and the experimental dates were further processed to be the more scientific relationship curves of all these dimensionless parameters

    通過對其過程式控制制方程的分析得出了影響床內氣粒兩相間傳熱nu數、傳質sh數的無因次運行參數，進而將實驗結果整理為更加科學的無因次相似準則間的關系曲線。
  2. Beijing, thursday, jan. 12 - a government environmental review has recommended reducing the number of dams included in a controversial hydropower proposal on the nu river in southwestern china in order to limit environmental damage and decrease the number of people who would be resettled, a hong kong newspaper has reported

    一家香港報紙報道， 1月12日（星期二） ，在北京，一份政府環評報告建議減少大壩的數量，以此來降低對環境的破壞以及移民的人數，其中包括中國西南部有爭議的怒江水電站項目。
  3. The end show that coefficient of convective heat transfer at thermal boundary condition is higher than that at definite heat flux boundary condition. if according to dimensionless equation of heat convection, nu number of the latter almost is mutiplied 1. 47 times of the formal, but the coefficient of convective heat transfer in tube between this two condition is almost equal

    研究結果表明:在實驗室中電加熱方式得到的管外對流換熱系數低於工程中傳熱條件下的管外對流換熱系數，若按傳熱準則式關系，後者的努謝爾特數約為前者的1 . 4倍;而管內的對流換熱系數在兩種邊界條件下的差別不大。
