| 摘 要： | 用针式掺气流速仪观测高速掺气水流中气泡的数量和直径。将小浪底工程泄洪洞中闸室原型与模型中相应测点的气泡资料对比后表明，原型中d＞2mm的气泡基本符合重力相似准则，可以在模型中模拟。

| Abstract: | Air bubble quantity and bubble dimension of high velocity aerated flow are measured by a needle type aeration and velocity meter. Comparison of the bubble data in the prototype and model of the middle chamber of Xiaolangdi Project shows that the bubble whose diameter is greater than 2 mm in prototype agrees to the gravity similarity law and can be simulated in the model. |
