摘要
:研究了气泡在毛细管端形成的基本规律 ,对于半径较小的毛细管 ,理论计算与实验结果是基本一致的。借助于高速摄像机进行液下气泡法检漏可以定量测出泄漏率 ,实验结果具有较好的重复性。探讨了介质物性、试验压力。
The regularity of bubble formation on capillaries was investigated. For capillaries with small radii, theoretical results coincide basically with experimental data. Using a high-speed video recorder, the leakage rate can be detected quantitatively by means of bubble emission method and experimental results indicate good reproducibility. The effect of the property of test medium, test pressure and pressurizing procedure on bubble formation was also discussed.
