摘要
通过重整化群方法探讨了含有掺杂随机杂质和不均匀性的薄膜的临界行为。基于有效空间维数与系统特征长度之间 fundamental relationship，考虑了杂质薄膜中的有限尺寸交叉。Demonstrated and investigated the difference between the critical properties of infinite systems and films. A new critical exponent, describing the scaling properties of the thickness of films with extended impurities has been deduced and calculated. A special attention is paid to the critical behaviour of real impure films.
