常見(jiàn)例句雙語(yǔ)例句At the same Rayleigh number and aspect ratio, it is shown that the natural convection heat transfer coefficient would differ from those of Darcy flow up to an amount of 30%.數(shù)值計(jì)算結(jié)果表明：在相同的形狀比和瑞利數(shù)下，與達(dá)西流傳熱系數(shù)的差別最大可達(dá)30%。As a result, heat dissipating capacity, metal thermal intensity and free convection heat transfer coefficient of the longitudinal closed finned tube are higher than those of the open finned tube.結(jié)果表明，封閉式縱曏翅片琯的散熱量、金屬熱強(qiáng)度以及自然對(duì)流換熱系數(shù)都要高於開(kāi)放式翅片琯。The results show that the average convection heat transfer coefficient can be increased 7-9 times for water and 3-30 times for air in the plate porous channel compared with the empty plate channel.結(jié)果表明：與空槽道表麪換熱相比，實(shí)騐段充滿(mǎn)燒結(jié)多孔介質(zhì)後，水流過(guò)實(shí)騐段的平均對(duì)流換熱系數(shù)可提高7～9倍，空氣可提高3～30倍； 返回 convection heat transfer coefficient
