摘　　要：在建筑火灾烟气运动的盐水模拟实验中，尚无简单易行的速度测量方法。我们将氢气泡技术应用于烟气运动的盐水模拟实验，不但可以仔细地显示流动状况，而且能定量地测量速度和速度分布。我们用这方法测量了走廊中烟气流动的速度，得到的结果合理可信。In the Experiment of salt water simulation of smoke movement of building fires ,there is not a simple and effective method of speed measurement yet. Not only the flowform of the smoke movement can be showed clearly, but also the speed and its distribu-tion can be measured quantitativly when hydrogon bubble technique is applied to the ex-perment. The speed of the smoke flow in a corridor has been measured whith themethod and the result is plausible,
