摘要翻译：
我们表明，自然时间本身在时间反转下的波动与尺度的依赖性为区分地震电信号（临界动力学）和人为源噪声以及确定尺度指数提供了一个有用的工具。我们给出了最近在地球表面探测到的电信号的数据，这些数据证实了自然时间的熵值和时间反转时的熵值都小于“均匀”分布的熵值。

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.
