| 摘要: |
| 在 KD-03 低速风洞中研制了一种附面层可入为地控制的均匀抽吸地板系统。在不同来流速度和不同抽吸系数条件下，对均匀抽吸地板上附面层速度分布进行了实验研究。实验结果与理论计算结果一致。在该地板上的高速列车模型风洞实验的结果与国外同类模型在移动带地板上的实验结果一致。利用均匀抽吸地板可有效地消除附面层的影响，从而提高模型风洞实验气动力的试验精度。 |

| Abstract: |
| A plate with uniform boundary layer suction is developed，on which the boundary layer can be controlled. The boundary layer velocity distribution on this plate is studied in various main flow velocities and suction coefficients. The experimental results are consistent with the calculation's，and the experimental results of the high speed train models on this plate are also consistent with the foreign results of the similar models on moving ground. The effect of the boundary layer can be eliminated effectively by using uniform suction plate，and thereby the air forces of models can be measured more exactly. |
