The linear dynamics of ion sputtered solids is essential to understanding the evolution of ordered and disordered surface patterns. We review the existing models of linear dynamics and point out qualitative discrepancies between theory and experimental observations that characterize the linear regime. In particular, we emphasize the importance of experimental and theoretical analysis of bifurcation points: certain values of control parameters such as ion beam angle or energy, where flat surfaces undergo a transition from stability to instability.
离子溅射固体的线性动力学对于理解有序和无序表面图案的演变至关重要。我们回顾了现有的线性动力学模型，并指出了表征线性区域的理论与实验观察之间的定性差异。特别是，我们强调了对分岔点进行实验和理论分析的重要性：分岔点是指某些控制参数的值，如离子束角度或能量，在这些点上，平坦表面会从稳定状态转变为不稳定状态。
