摘要翻译：
在可变形衬底上沉积的应变外延膜经历了一个形貌不稳定性，通过表面扩散使弹性能松弛。推导了具有润湿相互作用的薄膜的非线性和非局域动力学方程，并对其进行了二维和三维数值求解。超过一定的临界厚度，表面会向一个由湿润层隔开的岛状排列演化。孤岛化学势随体积的增大而减小，从而使体系经历一个由幂律描述的非间断粗化，并具有明显的维数依赖性。

英文摘要：
A strained epitaxial film deposited on a deformable substrate undergoes a morphological instability relaxing the elastic energy by surface diffusion. The nonlinear and nonlocal dynamical equations of such films with wetting interactions are derived and solved numerically in two and three dimensions. Above some critical thickness, the surface evolves towards an array of islands separated by a wetting layer. The island chemical potential decreases with its volume, so that the system experiences a non-interrupted coarsening described by power laws with a marked dimension dependence.
