【摘要】 本文利用１９４７ ～１９９０ 年加拿大Ｏｔｔａｗａ 的２８００ ＭＨｚ 太阳射电流量与太阳绕太阳系质心运动的角动量变化率ｄＬ／ｄｔ 做线性相关，当迟滞时间τ～３ 年得相关系数为０ ．８２２ ，线性相关置信水平远大于９９ ．９ ％ 。本文还用同期的太阳黑子相对数与太阳角动量变化率ｄＬ／ｄｔ 做线性相关，当迟滞时间τ～２ － ３ 年得相关系数为０ ．８２９ ，其置信水平亦远大于９９ ．９ ％ ，证实了董士仑在１９９７ 年在天体物理学报发表的结果（１９００ － １９８０ 年，τ～２ 年，相关系数为０ ．８１）更多还原

【Abstract】 In this paper, the solar radio flux at 2800MHz from Ottawa during 1947-1990 has been used to make linear correlation with dL/dt, the rate of change of the angular momentum of the Sun around the center of mass of the solar system. A coefficient of correlation, 0.822 with a confidence level far higher than 99.9% is found, when the time lag τ～2-3 years. In the same period of time the linear coefficient of correlation of the relative sunspot number with dL/dt is 0.829 with a confidence level far higher than 99.9%. The results further confirm these in [5] (coefficient of correlation～0.81 for 1900-1980 and τ～2 yrs).更多还原
