摘要
泰勒定律是著名的幂律(TPL),用于分析自然界中许多波动物理现象的缩放行为。该定律的缩放指数 b 构成了精确概率密度函数所对应的聚集过程的基础。在某些现象中,我们观察到小分区的聚集体具有周期性成分的 TPL 行为,特别是对于 b=1 值的物理过程,其中与波动相关的聚集过程得到泊松分布的支持。我们打算证明,当 b 值非常接近统一时,有可能在 TPL 的双对数尺度中发现一种趋势,即在方差和均值之间存在 "周期模式"(成分)。这种行为在其他二项分布中也能发现,泊松分布是其中的一种特殊情况,其映射的特点是方差接近 1。
Singularities of Taylor’s power law in the analysis of aggregation measures
Taylor’s law is a well-known power law (TPL) for analysing the scaling behaviour of many fluctuating physical phenomena in nature. The scaling exponent of this law forms the basis of the aggregation process to which a precise probability density function corresponds. In some phenomena, TPL behaviour with periodic components of the aggregates has been observed for small partitions, especially for physical processes characterised by values of where fluctuation-related aggregation processes are supported by Poissonian distributions. We intend to show that for values of very close to unity it is possible to find a trend, in the double logarithmic scale, of the TPL that there are ‘periodic patterns’ (components) between variance and mean. This behaviour is found in other binomial-type distributions, of which the Poissonian is a particular case, with mappings characterised by a variance close to 1.

Physica A: Statistical Mechanics and its Applications
Recognized by the European Physical Society
Physica A publishes research in the field of statistical mechanics and its applications.
Statistical mechanics sets out to explain the behaviour of macroscopic systems by studying the statistical properties of their microscopic constituents.
Applications of the techniques of statistical mechanics are widespread, and include: applications to physical systems such as solids, liquids and gases; applications to chemical and biological systems (colloids, interfaces, complex fluids, polymers and biopolymers, cell physics); and other interdisciplinary applications to for instance biological, economical and sociological systems.
