| 摘 要： | 本文通过交叉谱分析揭示了地球自转存在１５２个月，１２个月和６个月的显著周期。赤道东太平洋ＳＳＴＡ存在３８个月，２１４个月，５１个月和３个月的显著周期，并且二者在３８个月和１５２个月的周期上关系密切。落后时间长度谱显示，对于３８个月和１５２个月的周期，海温的变化能影响地球自转的速率；而对于２１４个月的周期，地球自转的变化能影响海温场的变化，但此为次要因素。

| Abstract: | By using cross spectrum analysis this article reveals that the earth rotation has obvious periods of 152 months,12 months and 6 months,Equator-eastern Pacific SSTA have period of 38 months,21 4 months,5 1 months and 3 months And period of 38 months and of 152 months are closely related Lag-temporal spectrum show that the sea temperature variation of 38 months and 152 months can affect the earth rotation speed;while the earth rotation variation of 21 4 months can affect the sea temperature variation,but this effect is secondary |
