摘要
本文根据对各个太阳黑子活动周的黑子相对数平滑年平均极大值R_M和极小值R_m的统计分析,得到了文中的一些统计相关特性,并利用这些统计相关特性对第22周的R_m(22)和第23周的R_M(23)进行了预测.同时又根据较相似的周期的一些特性对第22周极小时间t_m(22)和第23周极大时间t_M(23)进行了预测,结果如下:
Based on statistical analysis of the maximum R_M and minimum R_m of smoothed yearly mean sunspot numbers for each solar cycle, some statistical relative characte-ristics were obtained, by which we predicted the minimum R_m of smoothed yearly mean for the cycle No. 22 and the maximum R_M of smoothed yearly mean for the cycle No. 23. Also predicted were the times of the minimum and the maximum smoothed yearly mean sunspot number for the cycle No. 22 and the cycle No. 23. respectively, according to some characteristics of similar cycle.
