In cumulus convection ascent rates of several metres a second give a cooling rate of a few degrees per minute. 在積雲中，每秒幾米的對流上升速度造成的冷卻速率為每分鐘幾度。
The results revealed that increasing either jet velocity or subcooling degreealways promotes the hot surface cooling rate. 實驗結果表明，無論是增大工質過冷度還是提高射流速度，總會使得熱壁面的冷卻速率加大。
Fast cooling speed was the main reason of generating cold crackle. 認為冷卻速度過快是產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。
The cooling in gradient method was applied, the uneven cooling speed was avoided. 通過工藝改進，採用自上而下的梯度式降溫方式，避免了降溫速度不均勻的問題。
