用直接标度分析方法研究了分子束外延生长和在长程时间、空间关联条件下的动力生长过程。分别得到了在强、弱耦合区的粗糙指数和动力学指数,并对其结果进行了讨论,说明了其弱耦合的结果与动力重整化群的结果一致的原因。Molecular-beam epitaxy and dynamic growth with long-range space and temporal correlations are analysed using scaling analysis approach. Rough and dynamic exponents are gained in strong-coupling and weak-coupling region respectively. Discussions are given and the reason why the weak-coupling region results are agree with that of dynamical renormalization group is also explained.
