太阳活动起源研究(I):太阳活动周的经验和半经验模型

Researches on the Origin of Solar Activity (I): The Empirical and Semi-empirical Models of Solar Cycle

概括了从观测上发现的太阳活动主要特征，对Ｂａｂｃｏｃｋ的太阳活动周经验模型和Ｌｅｉｇｈｔｏｎ的半经验模型分别作了阐述，简要讨论了与Ｂａｂｃｏｃｋ和Ｌｅｉｇｈｔｏｎ模型有关的后续研究情况。

The main observed characteristics of solar activity are summarized at the beginning. Then the Babcock's empirical model and the Leighton's semi-empirical model of solar cycle are de- scribed respectively Finally the following researches related to the Babcock's and Leighton's models are briefly discussed.
