| 摘 要： | 讨论了包含界面的两相系统的平衡稳定性。通过建立模型，根据熵增原理，得出结论，即对含界面的两相系统，例如气体中的液滴或液体中的气泡。当其界面是球冠形状时，只有当球冠的高度小于球冠半径时，系统才能处于稳定的平衡状态。

| Abstract: | The present paper discusses the equilibrium stabiolity in a system that consists of two phases bounded by an interface. After setting up a model and judging from the principle of increase of entropy, we conclude that for a surface-included system which is in spherical crown shape, such as a vapor bubble inliquid or a liquid drop in vapor, only when the height is less than the bottom radius can it remain a stable equilibrium. |
