中文说明：基于重标极差(R/S)分析方法基础上的赫斯特指数(H)的研究是由英国水文专家H．E．Hurst(1900—1978)在研究尼罗河水库水流量和贮存能力的关系时，发现用有偏的随机游走(分形布朗运动)能够更好地描述水库的长期存贮能力，并在此基础上提出了用重标极差(R/S)分析方法来建立赫斯特指数(H)。作为
English Description：
Based on rescaled range (R / s) analysis method, Hurst index (H) was studied by British hydrologist h.e.hurst (1900-1978). When he studied the relationship between water discharge and storage capacity of Nile reservoir, he found that biased random walk (fractal Brownian motion) could better describe the long-term storage capacity of reservoir. On this basis, rescaled range (R / s) analysis method was proposed To establish the Hurst index (H). As
