摘要：
我们引入了一个磁性摩擦的简化模型，并利用数值与解析方法研究其行为。当阻力系数γ较大时，系统的运动遵循热激活过程。相反，当γ足够小时，滑动与粘滞状态表现为各自独立的亚稳态，晶格速度取决于滑动状态出现的概率。我们使用多种近似方法评估了这两种情况下的速度，并将结果与数值模拟进行了比较。
英文摘要：
We introduce a simplified model of magnetic friction, and investigate its behavior using both numerical and analytical methods. When resistance coefficient $γ$ is large, the movement of the system obeys the thermally activated process. In contrast, when $γ$ is sufficiently small, the slip and stick states behave as separate metastable states, and the lattice velocity depends on the probability that the slip state appears. We evaluate the velocities in both cases using several approximations and compare the results with those of numerical simulations.
