摘　　要：根据研制背景需求,开展了多孔板泡破点特性研究。对多孔板泡破点理论分析方法进行说明,并采取不同孔径多孔板进行了不同介质泡破点试验。试验结果表明,各相关因素对泡破点的影响与理论分析一致,实际测试值和理论计算值误差在±15%以内,可满足工程应用需求。多孔板可作为毛细元件应用于表面张力贮箱设计。The bubble point character of the perforated plate was explored according to the mission demand. The theoretical analysis method for the bubble point of the perforated plate was expounded. A bubble point test of three kinds of liquids was carried out with several perforated plates with different pore diameters. The test result shows that the influence of the concerned factors on the bubble point is in conformity with that of the theoretical analysis, and the error between the actual test value and the theoretically-calculated value is within ＋ 15% , which can meet the requirement of engineering application. The perforated plate can be used for the surface tension tank as a kind of capillary element.
