The results revealed that increasing either jet velocity or subcooling degreealways promotes the hot surface cooling rate. 實(shí)驗結果表明,無(wú)論是增大工質(zhì)過(guò)冷度還是提高射流速度,總會(huì )使得熱壁面的冷卻速率加大。
In cumulus convection ascent rates of several metres a second give a cooling rate of a few degrees per minute. 在積云中,每秒幾米的對流上升速度造成的冷卻速率為每分鐘幾度。
Fast cooling speed was the main reason of generating cold crackle. 認為冷卻速度過(guò)快是產(chǎn)生冷裂紋的主要原因。
The effects of cooling rate and reduction below Tnr on the microstructures and properties in HSLA Steel have been researched. 研究了控軋控冷工藝參數中冷卻速度和未再結晶區不同壓下量對低合金鋼的組織和性能的影響。
