摘要翻译：
本文详细研究了30只中国流通股连续1min波动率超过一定阈值($q$)之间的收益率区间($\tau_q$)的统计性质。Kolmogorov-Smirnov(KS)检验表明，对于不同的阈值$q$，12只股票在$\tau_q$分布上表现出标度行为。KS检验和加权KS检验表明，在5%的显著性水平下，有6只股票（12只股票中的6只股票）的标度收益区间分布可以很好地拟合为一个伸展指数函数$F(\tau/\bar{\tau}）\sim e^{-\alpha(\tau/\bar{\tau}）^{\gamma}}$,其中$\bar{\tau}$为平均收益区间，约为0.31$。通过对条件概率分布$P_q(\tau\tau_0)$和平均条件收益率区间$<\tau\tau_0>$的研究，证明了连续收益率区间区间之间存在短期相关性。我们进一步研究了一组$n$区间后的平均收益区间$<\tau\tau_0>$和波动$f(l)$,发现波动收益区间也存在长期记忆。

英文摘要：
  The statistical properties of the return intervals $\tau_q$ between successive 1-min volatilities of 30 liquid Chinese stocks exceeding a certain threshold $q$ are carefully studied. The Kolmogorov-Smirnov (KS) test shows that 12 stocks exhibit scaling behaviors in the distributions of $\tau_q$ for different thresholds $q$. Furthermore, the KS test and weighted KS test shows that the scaled return interval distributions of 6 stocks (out of the 12 stocks) can be nicely fitted by a stretched exponential function $f(\tau/\bar{\tau})\sim e^{- \alpha (\tau/\bar{\tau})^{\gamma}}$ with $\gamma\approx0.31$ under the significance level of 5%, where $\bar{\tau}$ is the mean return interval. The investigation of the conditional probability distribution $P_q(\tau | \tau_0)$ and the mean conditional return interval $<\tau| \tau_0>$ demonstrates the existence of short-term correlation between successive return interval intervals. We further study the mean return interval $<\tau| \tau_0>$ after a cluster of $n$ intervals and the fluctuation $F(l)$ using detrended fluctuation analysis and find that long-term memory also exists in the volatility return intervals.
