In this article, we use three multifractal analysis methods, which are partition function method, singular spectrum method and multifractal detrended fluctuation method, to analyse the closing price series during the past seven years in Shanghai Stock Market with different time scales.

作者将多重分形分析的三种方法（配分函数分析法、奇异谱分析法和多重分形趋势消除波动分析法）应用于我国上海证券市场在过去七年中的收盘指数序列，分析了不同时间标度对多重分形特性的影响。

For the singular spectrum analysis of time series, a method of constructing covariance matrix by using forth order cumulant is proposed. The method could restrain the Gaossian noise and symmetrical distributed noise mixed with chaotic signals.

对于时间序列的高阶奇异谱分析，提出了一种利用四阶累积量函数构造协方差矩阵的方法，该方法从理论上能有效地抑制叠加在混沌信号中的高斯噪声和对称分布噪声对重构结果的影响。

Thereinto, for the spectral decomposition estimate of the covariance matrix ,we can gain the risk functions under some losses.

其中，对于观测向量协方差阵的谱分解估计，我们很容易得到它在一些损失下的风险函数。

The article based on practical problems finds two ways:point operation of an image and power spectral density function .

本文的研究工作从实际出发，通过对雷达图像的长期观察，总结出规律，然后根据规律找到两种过滤地物杂波的新方法：图像的点运算和图像的功率谱密度函数法。

Aiming at the power spectral density function of Clough-Penzien model, value of peak ratio of ground motion in simulation is suggested.

针对Clough-Penzien功率谱密度函数，建议了模拟多点地震动的峰值因子的取值。

Finally, we optimize the allocation of a portfolio based on spectral risk measure. The optimization results are fully explained.

最后，提出了以谱风险度量为目标函数的投资组合优化配置模型，并讨论了模型的求解结果。

Therefore it can perform localized cross spectral analysis to measure phase shifts between each of multiple components of two time series as a function of both time and frequency.

因此可以用局部交叉谱来衡量两个时间序列中多种成分之间的相移，作为时间和频率的函数。
