根据实验观察,正压气泡的上升运动可分为直线型、准谐振动型、螺旋线型和翻滚运动型。我们选择适当的物理模型对各类运动进行了理论分析,并对气泡内气体分子运动机理进行了探讨,其结果与实验观察相符。 According to experimental observation, positive pressure bubble rising movement can be divided into linear, quasi-harmonic vibration type, spiral type and rolling sports. We choose the appropriate physical model for a variety of sports conducted a theoretical analysis, and gas bubble molecular motion mechanism were discussed, the results consistent with the experimental observations.
