It also gives the definitions and stochastic properties of pure random process, random walk process and AR(1) autoregressive process, and analyses the simulative data of three typical random processes using wavelet analysis, frequency spectrum analysis and time-correlation analysis. The stochastic properties of time series and the trend component, the time length of time-correlation and the properties of main frequency of these three typical random processes are summarized as the templates for further research.

This paper is studying fluctuation of price, backwardation and contango in future markets. Based on the theory of future market and spot market, it takes a further analysis of Robert and Nir's study of backwardation in oil future markets. By data acquisition and processing, descriptive statistics and time series analysis, it investigates the relationship between backwardation and the equilibrium of oil future prices and spot prices.

Such experts are specified by the tenderer from the experts beadroll, provided by the relevant departments of the State Council or the related section of the People's government of province, autonomous reagion and municipality directly, or the relevant profession experts list from the expert pool provided by the tender agency.

前款专家应当从事相关领域工作满八年并具有高级职称或者具有同等专业水平，由招标人从国务院有关部门或者省，自治区，直辖市人民政府有关部门提供的专家名册或者招标代理机构的专家库内的相关专业的专家名单中确定；一般招标项目可以采取随机抽取方式，特殊招标项目可以由招标人直接确定。

However, the practice of WTO Panels and the Appellate Body reveals that these rules and criteria are not consistently complied with and the formation thereof is hardly justified. The traditional principle that those who claim or defend bear the burden takes no account of substantial justice and may be readily abused in hearings. Moreover, the analysis of the disparity between exception and exclusion proves meaningless, the hierarchy of criteria seems irrational, and the legal ground for exception to distribution of burden of proof is under debate.

遗憾的是，专家组和上诉机构的实践表明，他们并没有严格遵守其形成的相关举证责任分配规则，其形成的相关标准也缺乏合理性：传统的谁主张谁举证原则由于忽视了实质公平，在WTO审理实践中容易被滥用；例外规定与排除规定之间存在区别的分析多此一举；重要性等级标准缺乏合理性及例外规定作为举证责任分配的标准既没有法律依据，其合理性也受到质疑。
