摘要
古代典籍中“大如X”形式的黑子记录是古人对黑子面积大小的一种估测 ,可利用古人目视观测天象时天球模型对其描述进行量化。文章按照视觉生理学原理 ,利用统计方法 ,并参照扁平天穹归算模型 ,对古籍中 95条黑子“大如X”记录的 1 7种比体进行了面积和实际大小的归算。
The records of “big as X” of sunspots in annals were estimation and measurement about the area of sunspots. One can quantify and reduce them with the celestial sphere model of observing astronomical phenomena with the naked eyes. The author uses the principle of seeing physiology and statistical method and the model of the plane vault of heaven to reduce to the area the scale of 17 comparative objects that come from 95 records of “big as X” of sunspots in annals.
