Furthermore, how to apply the model efficiently in practice is deeply discussed. As the variance produced by the forecasting model as concerned, the real-time revised method of hydrological forecasting is highlighted. Next arranged, the multi-stratum recursive prediction model is put forward to forecast the error series that is a dynamic system. Later, an error selfregressive multi-stratum recursive prediction model is set up as well as a current algorithm offered. Finally, the difference collated model and the gloss control method, which are devoted to updating the mid-long term hydrological forecasting during the meditate period, are put forward.

在综合评述中长期水文预报现有方法和模型的基础上，采用时间序列分析方法，建立中长期水文预报的时间序列组合模型，并对模型如何在实际中有效应用作了较为深入的探讨；针对模型预报所产生的误差，又重点研究了水文预报实时修正方法：提出了采用多层递阶预报方法对误差序列这一动态系统进行预报，建立了误差自回归多层递阶预报模型，并提出了较为通用的解算方法；给出了水文中长期预报中期修正的残差相关模型和总量控制方法。

To build an appropriate mathematic model of the random drift of flexible gyro ,two methods are discussed,using non-stationary time series analysis and using stationary time series analysis based on wavelet discomposition.

With the development of society, many uncertain elements impose influences on economy, which should be attached importance to people. In 1970, Box and Jenkins proposed an analytical method of time series based on random theory which not only takes the theory of time series analysis to a new level but also promotes the preciseness of prediction.

随着社会的发展，许多不确定因素在经济生活中的影响越来越大，必须引起人们的重视。1970年，Box和Jenkins提出了以随机理论为基础的时间序列分析方法，使时间序列分析理论上升到了一个新的高度，预测的精度大大提高。

On the basis of statistical theory of time series, the characteristics and self relativity of Internet time-delay were analyzed statistically. The prediction method of network delays based on support vector machine was put forward.

It is more valuable in time series analysis than unstandardized principal analysis.2 Fourier Analysis can decompose a time series signal into different frequency components, which represent different seasonal mode.3 The Phenology characteristics extracted from multi-temporal NDVI data are used for a vegetation classification.

2傅立叶分析将时间序列信号分解到不同频率成分中，各个成分分别代表了不同的周期变化模式，其中1/12频率分量概括了植被全年的单峰的季节性变化模式。 3多时相NDVI数据的时间序列分析结果中蕴含了植被的生物学信息，利用这些信息进行遥感分类。

I made 'natural sciencedictionary' which is edited in chief by Zhenhuan JIANG ( superscribed by Jiaxi LU,preluded by Sanqiang QIAN ) as my source of statistics and adopt the researchmethod of statistic computation. As a result of my research, I get aggregatedeveloping time series analysis of technological sciences and time series analysis offour-layer technological sciences. Then, I combine statistic computation with historyreview. After category definition and corroboration about technological sciences isestablished integrally and accurately.
