例句與造句

1. Normally , coefficient of convective heat transfer is gotten through experiments which is heating testing tube by electricity and computed through newton cooling law
   通常,對流換熱系數(shù)是在實驗中以電加熱試驗管壁面后根據(jù)牛頓冷卻定律計算得來的。
2. At the same time , we suggest a correction factor to the before coefficient of convective heat transfer formula at the second boundary condition
   然后研究平均對流換熱系數(shù)在電加熱邊界條件和傳熱邊界條件下的區(qū)別,同時提出對以往在電加熱條件下所得出的換熱系數(shù)經(jīng)驗式的修正。
3. So if there is any difference of coefficient of convective heat transfer between this two boundary condition ? both numerical simulation and experiment were adopted to research ducted heat convection
   探討這兩種邊界條件下管內(nèi)外的對流換熱系數(shù)的差別及相應(yīng)的對應(yīng)關(guān)系對于換熱設(shè)備的設(shè)計具有重要的意義。
4. Fist we resarch local wall temperature ouside and inside of tube , local fluid temperature inside and outside of tube , local heat flux inside and outside of tube , local coefficient of convective heat transfer inside and ouside of tube along the tube axial direction
   首先研究在這兩種情況下管內(nèi)(外)壁溫、管內(nèi)(外)流溫、管內(nèi)(外)壁面局部熱流密度、管內(nèi)(外)局部對流換熱系數(shù)沿管子軸向的變化。
5. 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(jié)果表明:在實驗室中電加熱方式得到的管外對流換熱系數(shù)低于工程中傳熱條件下的管外對流換熱系數(shù),若按傳熱準(zhǔn)則式關(guān)系,后者的努謝爾特數(shù)約為前者的1 . 4倍;而管內(nèi)的對流換熱系數(shù)在兩種邊界條件下的差別不大。
