摘　　要：介绍了空气横掠水平圆管强迫对流换热的实验原理和清华大学热工学实验室的实验系统的设计,并根据相似原理整理了使用本系统测试的实验数据,对实验数据进行了分析与讨论。实验系统结构合理紧凑、实验精度较高,能够较好地满足实验与教学的需要。The experimental principles and experimental systems of forced heat convection for circular tubes are intro- duced. The experimental data dealt based on the analogy principles are further analyzed and discussed. The experimental systems are rather compact and with high accuracy in performance, which can meet application requirements of instructional experiments.
