研究了网络时延数据序列的统计特性。分析过程中，分别采用基于谱密度构造统计量方法、周期图法、JB检验方法研究了网络时延数据序列的平稳性、周期性、正态性。最后，基于校园网应用层获得时延数据并通过MATLAB 仿真。结果表明，网络时延数据是平稳的、不含有周期项，且呈反正态性的。

The statistical characteristics of the network delay is researched.In the process of analysis,its stability,periodicity and normality are analysized respectively by the method of constructing statistic based on spectral density,the cycle diagram method and the JB test method.Finally,the delay data is ob-tained based on the application layer of the campus network.Simulation results show that the data of the network delay is smooth,aperiodic but not in normal distribution.
