Using the quasistatic Tomlinson model as a simple representation of an atomic force microscope, conditions for transitions in atomic-scale friction behavior from smooth sliding to single slips and then multiple slip regimes are derived based on energy minimization. The calculations predict and give a general explanation for transitions between different stick-slip regimes in the limit of low damping. The predictions are consistent with experimental observations of these transitions.
使用准静态汤姆林森模型作为原子力显微镜的一种简单表示，基于能量最小化推导了原子尺度摩擦行为从平滑滑动到单滑移再到多滑移状态转变的条件。这些计算预测并给出了在低阻尼极限下不同粘滑状态之间转变的一般解释。这些预测与这些转变的实验观察结果一致。
