舰船尾流气泡特性的研究是研制水下声、光尾流探测装备的基础。从受力分析的角度出发，对水中气泡在上浮过程中的速度方程、径向运动方程进行了理论推导与数值计算，得到了水中气泡上浮过程中的半径、速度以及在水中停留时间的变化规律。采用空气泵产生压缩空气，并通过微孔陶瓷管释放的方法建立了水中气泡产生及控制平台，系统通过调节空压泵气压，产生不同大小、密度、运动速度的气泡源，并采用片光源、短曝光时间相机对不同气泡特性进行了测量分析。实验结果与数值计算、文献报道的结果较好地得到吻合，为舰船尾流气泡特性研究提供理论及实验基础。

The study of warship wake bubbles is the foundation of object detection for wake detection technique. In view of stress analysis, theory analysis and numerical value computation are carried out for velocity equation of bubble in the up-float process and radial movement equation. The producing and controlling system of bubble is established through the air pump and chinaware. The bubble characteristic of different size is obtained based on line lighting, photography and numeric image disposal. The result has matched with numerical computation and reference preferably. These works is favorable for the study of bubbles in ship wakes.
