摘要
提出以正弦函数拟合序列的周期分量并进行周期分量显著性检验的方法。对南宁年平均气温序列和梧州年降水量序列进行了周期分析。
The calculations of periodic components by sine function and significance level of periodic components are conducted in the analysis of the period of climatic time series by using maximun entropy spectrum.The periods of annual mean temperature time series in Nanning city and annual amount precipitation time series in Wuzhou city of Guangxi are also computed.
