标题： A Conjecture Concerning the Rieger and Quasi-Biennial Solar Periodicities

摘要： 已经确定，大约153天的里格尔周期是多重周期复杂现象的一部分，所有这些周期都是一个基本周期（约25.5天）的整数倍。然而，尚不清楚为什么这个周期的第六次亚谐波会被优先表现出来。 我们注意到，如果太阳包含两个旋转成分，具有不同的周期和不同的轴，那么当这两个周期具有最小公倍数时，会出现一种特殊的情况，因为在这种情况下的两个旋转成分的相对配置将在那个（最小公倍数）周期内完全重复。 这一思路使我们怀疑太阳中包含第二个旋转成分，其自转周期在21至22.5天之间。 显示英文摘要

摘要： It has been established that the Rieger periodicity of approximately 153 days is part of a complex of periodicities, all multiples of a basic period of approximately 25.5 days. However, it has not been clear why the sixth subharmonic of this periodicity should be preferentially manifested. We here note that if the Sun contains two rotating elements, with different periods and different axes, a special situation will arise if the two periods have a lowest common multiple, for in this case the relative configuration of the two rotators would repeat exactly at that (LCM) period. This chain of thought leads us to suspect that the Sun contains a second rotating element with rotational period in the range 21 - 22.5 days.
