传热速率是指间壁两流体单位时间的换热量。聚合反应器的传热计算与一般传热计算相同，为有利于提高传热速率，对高放热、高黏度的聚合反应，就更要求反应物料纯净，不被污染；要求装置内表面光滑，不易挂胶，不存在易结垢的死角，并便于清理。
结果表明(火用)损失和化学反应及传热速率成正相关。
The results show that the exergy loss is directly proportional to the rates of chemical reaction and heat transfer.
因此，在沥青基炭纤维形成过程中，控制温度和传热速率是极为关键的。
Therefore, the control of both temperature and heat-transfer rate is extremely critical during the formation of pitch-based carbon fibers.
模型中采用传质、传热速率方程表征实际塔板上的传递过程，避免了级效率的计算。
Mass and energy transfer rate equations are used in describing the transfer processes on real trays and thus the computations of stage efficiencies are entirely avoided.
