摘　　要：本文利用三维超声风速温度仪及数字三杯式风速仪,测量了列车风的速度分布,初步探讨了速度场的诸多特性——非定常特性,沿侧向分布特性,与列车速度、自然风风向、风速关系等。The velocity distribution of air flow around a train was measured by using the ultrasonic anemometer-thermometer and digital three-cup anemometers. This paper discussed the velocity field features of air flow around a train-non-stationary feature, velocity distribution along a cross-section, and relations between train speed, wind direction and wind speed.
