针对气泡连通装置的平衡稳定性分析，引入“气泡坐标”概念，并采用最小能量法定量分析气泡初始状态对两连通气泡平衡稳定性的影响，准确解释了对此类问题的定性分析结果. 同时，实验表明数值计算结果与实验测量结果之间误差极小，从而进一步验证了使用最小能量法分析气泡连通装置平衡稳定性的有效性与准确性.

To study the equilibrium stability of the bubble connecting device，the concept of bubble

coordinate is introduced.Basedon this，the minimum energy method is used to quantitatively analyze

the influence of bubble's initial state on bubble's equilibrium stability. The results are in full

agreement with the qualitative analysis. Mean- while，the experiment shows that the error between

the results of numerical computation and the experiment results are very small. So the validity

and accuracy of the equilibrium stability analysis of the bubble connecting device by using the

minimum energy method are verified.

Key words： bubble coordinate; surface energy; equilibrium stability analysis; minimum energy method
