The results revealed that increasing either jet velocity or subcooling degreealways promotes the hot surface cooling rate. 实验结果表明,无论是增大工质过冷度还是提高射流速度,总会使得热壁面的冷却速率加大。
In cumulus convection ascent rates of several metres a second give a cooling rate of a few degrees per minute. 在积云中,每秒几米的对流上升速度造成的冷却速率为每分钟几度。
