摘要翻译：
在最近的模拟和滑行细菌聚集实验的推动下，我们研究了二维自推进硬棒在基底上的集体动力学模型。这些杆具有有限的尺寸，通过排除体积相互作用，它们的动力学因与基底的相互作用而过阻尼。从含有非热噪声源的微观模型出发，导出了系统的连续介质描述。然后用流体力学方程来表征系统的可能稳态，以及它们的稳定性随粒子堆积分数和自推进速度的变化。

英文摘要：
  Motivated by recent simulations and by experiments on aggregation of gliding bacteria, we study a model of the collective dynamics of self-propelled hard rods on a substrate in two dimensions. The rods have finite size, interact via excluded volume and their dynamics is overdamped by the interaction with the substrate. Starting from a microscopic model with non-thermal noise sources, a continuum description of the system is derived. The hydrodynamic equations are then used to characterize the possible steady states of the systems and their stability as a function of the particles packing fraction and the speed of self propulsion.
