我们提出了一个简单的模型来分析微流体“双网络”中液滴的流量。这种由两种通道组成的功能网络，即液滴可进入或禁止进入的通道，往往表现出动力系统的复杂行为特征。通过关注最近提出的三种配置，我们为它们的显著行为提供了一个解释。此外，该模型允许我们预测在不同参数下的行为。验证将澄清基本问题，如网络对称性，驱动条件的作用，可逆行为的发生。该模型适合于快速的数值实现，因此可以帮助设计设备，识别参数窗口，其中行为足够健壮，使设备具有实际用途，并探索新的功能。
We propose a simple model to analyze the traffic of droplets in microfluidic "dual networks." Such functional networks which consist of two types of channels, namely, those accessible or forbidden to droplets, often display a complex behavior characteristic of dynamical systems. By focusing on three recently proposed configurations, we offer an explanation for their remarkable behavior. Additionally, the model allows us to predict the behavior in different parameter regimes. A verification will clarify fundamental issues, such as the network symmetry, the role of the driving conditions, and of the occurrence of reversible behavior. The model lends itself to a fast numerical implementation, thus can help designing devices, identifying parameter windows where the behavior is sufficiently robust for a device to be practically useful, and exploring new functionalities.
