自然时间和熵在时间反演下的波动区分了不同动力学的相似电信号
The fluctuations, under time reversal, of the natural time and the entropy distinguish similar looking electric signals of different dynamics
摘要：
我们表明，自然时间本身的波动在时间反演的尺度依赖性提供了一个有用的工具，地震电信号（临界动力学）从人造源发出的噪声的歧视，以及为确定标度指数。我们提出了最近的数据，在地球表面检测到的电信号，这证实了在自然时间的熵值，以及它的值下的时间反转小于熵的“均匀”分布。
英文摘要：
We show that the scale dependence of the fluctuations of the natural time itself under time reversal provides a useful tool for the discrimination of seismic electric signals (critical dynamics) from noises emitted from man made sources as well as for the determination of the scaling exponent. We present recent data of electric signals detected at the Earth's surface, which confirm that the value of the entropy in natural time as well as its value under time reversal are smaller than that of the entropy of a "uniform" distribution.
