本文用非平衡统计力学的观点分析盘基网柄藻的电击运动。由于可以观察到细胞轨迹的波动行为,我们借助波动定理分析了细胞轨迹的概率分布。近年来,涨落定理在胶体体系中的有效性得到了验证,它也被应用于颗粒体系、湍流体系和化学振荡波中,以研究它们的一些尚未完全理解的统计性质。注意到涨落定理可能适用于细胞电趋化,这里我们用它来帮助我们获得这个生物系统的唯象模型。

英文摘要:
In this paper, we analyze the electrotactic movement of Dictyostelium discoideum from the viewpoint of non-equilibrium statistical mechanics. Because we can observe fluctuating behavior of cellular trajectories, we analyze the probability distribution of the trajectories with the aid of the fluctuation theorem. Recently, the validity of the fluctuation theorem was verified in a colloidal system, and it has also been applied to granular systems, turbulent systems and chemical oscillatory waves to investigate some of their statistical properties that are not yet completely understood. Noting that the fluctuation theorem is potentially applicable to cellular electrotaxis, here we employ it to help us obtain a phenomenological model of this biological system.
