摘要
利用Ｇｕｉｌｌｅｒｍｏ的单时间序列重构相空间点概率密度的功率谱分析方法，对赤 道日表层水温和青岛月气温的九点滑动平均资料进行了隐含频率检测，结果表明，赤 道日表层水温隐含周期为 ２３．３，１０．５，７．７ ｄ，其他物理参量的震荡及青岛气温隐含周 期 １０．６，５．７，４．５，２．９ ａ，３个月其他物理参量的震荡．
The equator day SST time series(ESST) and the nine points moving average month air temperature data of Qingdao (NMAMAT) are detected using the frequencies spectrum and the probability density of points in reconstructed phase space. The results show that the hidden periods of other physical variables in ESST system and NMAMAT system are 23. 3, 10. 5, 7. 7 d and 10. 6, 5. 7, 4. 5, 2. 9 a, 3 months, respectively. The physical variables of these hidden periods are guessed by experience in knowledge of these systems.
