本文用蒙特卡罗模拟方法研究了近程竞争磁场($H$)作用于相对壁面的约束磁Ising膜中损伤的传播。由于场的存在，薄膜在一个明确定义的临界温度$T_w(h)$处发生润湿转变。实际上，竞争场导致了不同取向磁畴之间的界面。对于$t<T_w(h)$($t>T_w(h)$)，这样的界面与壁有界（无界），而在$T_w(h)$处，界面基本上位于薄膜的中心。发现界面的存在大大增强了损伤的时空扩展，界面作为损伤的“催化剂”，导致总损伤面积的增加。用有限尺寸标度法外推到热力学极限，计算损伤扩展的临界点。此外，与Ising模型有序-无序转变特征的临界温度相比，润湿转变有效地移动了损伤扩展临界点的位置。这样的临界点位于非湿相中。

英文摘要：
  The propagation of damage in a confined magnetic Ising film, with short range competing magnetic fields ($h$) acting at opposite walls, is studied by means of Monte Carlo simulations. Due to the presence of the fields, the film undergoes a wetting transition at a well defined critical temperature $T_w(h)$. In fact, the competing fields causes the occurrence of an interface between magnetic domains of different orientation. For $T < T_w(h)$ ($T > T_w(h)$) such interface is bounded (unbounded) to the walls, while right at $T_w(h)$ the interface is essentially located at the center of the film.   It is found that the spatio-temporal spreading of the damage becomes considerably enhanced by the presence of the interface, which act as a ''catalyst'' of the damage causing an enhancement of the total damaged area. The critical points for damage spreading are evaluated by extrapolation to the thermodynamic limit using a finite-size scaling approach. Furthermore, the wetting transition effectively shifts the location of the damage spreading critical points, as compared with the well known critical temperature of the order-disorder transition characteristic of the Ising model. Such a critical points are found to be placed within the non-wet phase.
