本文针对高雷诺数下的圆柱绕流问题，以火焰熄灭为例进行了相关的实验研究. 结果表明在一定范围内，火焰熄灭时间与障碍物直径、蜡烛与障碍物之间的距离、蜡烛燃烧速率成正比关系，与气流流速成反比关系. 通过分析发现实验数据与理论分析一致，说明了文章的实验方法可行、结论正确，为深入研究圆柱绕流、火焰燃烧问题及二者之间的联系提供了重要支撑.

In view of high Reynolds number flow around a cylinder, the problem of how to put off a fire is carried out based on experimental research. It is showed that within a certain range, the flame extinction time is proportion to the obstacle diameter, the distance between candles and obstacles and the candles burning rate, and it is inversely proportional to the flow velocity of the obstacle. Through the analysis, it is found that the experimental data and the theoretical analysis are consistent, which indicate that the experiment conclusion is correct and the experimental method is feasible. Furthermore, it provides an important support for the indepth study of the flow around a cylinder, flame combustion problems and the relationship between them.
