存在噪声时的II型不连续性特性

Type-II intermittency characteristics in the presence of noise

Alexey A. Koronovskii, Alexander E. Hramov

摘要:

我们考虑一种类型的间歇性的行为,发生的结果之间的相互作用的动力机制,引起II型不稳定性和随机动力学。我们解析地推导出了迄今为止从未得到过的层状相分布规律。作为所进行的研究的必然结果,已经知道层流相的平均长度对临界参数的依赖性[PRE 68(2003)036203]。我们还证明,这种依赖性得到较早的假设下的固定形式的再注入概率不依赖于再层化性质,相应地,得到的表达式的临界参数的层流相的平均长度仍然正确的不同类型的再注入概率。

英文摘要:

We consider a type of intermittent behavior that occurs as the result of the interplay between dynamical mechanisms giving rise to type-II intermittency and random dynamics. We analytically deduce the law for the distribution of the laminar phases, which has never been obtained hitherto. The already known dependence of the mean length of the laminar phases on the criticality parameter [PRE 68 (2003) 036203] follows as a corollary of the carried out research. We also prove that this dependence obtained earlier under the assumption of the fixed form of the reinjection probability does not depend on the relaminarization properties, and, correspondingly, the obtained expression of the mean length of the laminar phases on the criticality parameter remains correct for different types of the reinjection probability.
