用数值方法和解析方法研究了由两个布朗粒子组成的二聚体在周期衬底上的输运。在相同输运条件下，二聚体质心的迁移率和扩散率与单体的迁移率和扩散率相比具有明显的差异。平均电流和扩散系数都是驱动力的复杂非单调函数。研究了二聚体平衡长度、耦合强度和阻尼常数对二聚体输运性质的影响。

英文摘要：
  The transport of a dimer, consisting of two Brownian particles bounded by a harmonic potential, moving on a periodic substrate is investigated both numerically and analytically. The mobility and diffusion of the dimer center of mass present distinct properties when compared with those of a monomer under the same transport conditions. Both the average current and the diffusion coefficient are found to be complicated non-monotonic functions of the driving force. The influence of dimer equilibrium length, coupling strength and damping constant on the dimer transport properties are also examined in detail.
