耦合自组织：经历长波不稳定性的两个液体膜之间的热相互作用
Coupled self-organization: Thermal interaction between two liquid films undergoing long-wavelength instabilities
摘要：
两个薄的液体层之间的热耦合的影响，由一个气体层，进行了讨论。液体层经历由重力和热毛细应力驱动的长波长不稳定性。为了研究动态，进行线性稳定性分析和薄膜方程的完整数值解。结果表明，该组合系统的稳定性特性显着不同的情况下，这两个层相互独立地发展。最突出的是，振荡不稳定性，不存在于单液体层配置，可能会发生。
英文摘要：
The effects of thermal coupling between two thin liquid layers, separated by a gas layer, are discussed. The liquid layers undergo long-wavelength instabilities driven by gravitational and thermocapillary stresses. To study the dynamics, both a linear stability analysis and a full numerical solution of the thin-film equations are performed. The results demonstrate that the stability properties of the combined system differ substantially from the case where both layers evolve independently from each other. Most prominently, oscillatory instabilities, not present in single-liquid layer configurations, may occur.
