Based on the initial investigation, these records are divided into three types: 158 records are definite, 86 ones are doubtful and 2 ones are negative.

在我国史籍中的天象记录文字内,太阳黑子的记录大约有246条。本文将该记录分成几种情况进行初步讨论,从文义上可分为三种类型:确定型158条;存疑型86条;否定型2条。对这些记录的准确、可靠性的问题,还有待于进一步的研究与考证,希望能引起使用者和研究者注意。

As early as the Shang-Chou periods, the advanced time system was already defined, and the scientific predictions and observations of eclipses were also developed long ago. Unfortunately, most of the data has been lost. The authors hold that the remained observational data in ancient China are still abundant, lasting over a few thousands of years, and they can contribute to the solvement of the question of the long term variation of the earth's rotation.

As early as the Shang-Chou periods, the advanced time system was already defined, and the scientific predictions and observations of eclipses were also developed long ago. Unfortunately, most of the data has been lost. The authors hold that the remained observational data in ancient China are still abundant, lasting over a few thousands of years, and they can contribute to the solvement of the question of the long term variation of the earth's rotation. For this aim, we have colIected, examined and calculated 85 solar and 72 lunar eclipses. On the basis of the record ing time (apparent solar time) for a eclipse and its theoretical time (ephemeris time), the correction of ephemeris time ΔT is obtained. The results show that the discrepancy of the values of ΔT is not large, and these values are coincident with the trends of the empirical formula of AT in the present nautical almanac. Their accuracy is better than that of the results obtained with the method of central eclipses. Synthesizing the results of the eclipses in ancient China and Japan, the series of AT (the change of length of a day) and Δω/ω (20 years interval) are given in appendant table and some discussion are made briefly. The astronomical observational results in ancient China play an important role in the development of modern science, We should pay attention to this new problem.

中国自商周起就建立了先进的时法(其实就是历法的组成部分),并很早就开展了日月交食的科学预报和观测,可惜记录资料散失严重。本文认为。残存的中国古代交食时刻记录数量丰富源远流长,绵延数千年之久,对解决地球自转长期不规则性的问题同样能做出重大贡献。为此目的,我们一共收集,考证与归算了八十五例日食记录(自公元前134年至公元后1629年)与七十二例月食记录(自公元221年至1606年)。根据某食相的记录时刻(真太阳时)与计算的理论时刻(历书时),得到了它们的历书吋改正值ΔT。结果表明,ΔT值的弥散不大,它们符合现代天文年历中所用的ΔT经验公式的趋势,其偏差显著优于中心食方法的结果。综合各种有关天象记录得到的ΔT值,便能拟合一条反映地球自转长期(十年或百年尺度)不规则性的ΔT曲线。本文最后综合了由中国古代交食时刻记录,中国中心食记录以及日本古代交食时刻记录等资料得到的结果,给出了一个ΔT与Δω/ω的序列(以二十年为间隔),并做了相应的讨论

The folk chronometric system of 24-hour, as a companion of the methods of compiling the folk-little-calendar, was well preserved in fortune tellers' handbeeks. Its use was confined to selecting lucky moments for funeral ceremonies since Tang dynasty. But before 600AD, this system had been used in recording astro-phenomena for several hundrad years. The names of the hours and of the subdivisions (multiples of 5~m) are listed in conversion tables 1 and 5. The subdivisions (multiples of 10~m) of a duration unit...

The folk chronometric system of 24-hour, as a companion of the methods of compiling the folk-little-calendar, was well preserved in fortune tellers' handbeeks. Its use was confined to selecting lucky moments for funeral ceremonies since Tang dynasty. But before 600AD, this system had been used in recording astro-phenomena for several hundrad years. The names of the hours and of the subdivisions (multiples of 5~m) are listed in conversion tables 1 and 5. The subdivisions (multiples of 10~m) of a duration unit "chen" are listed in table 4. Quotations of contemporary appraisals about 2 calendars, by comparing their predictions of 5 eclipses in 221AD—223AD with observations, are taken for examples of chronometric conversions by tables 1, 5 and 4.

二十四时制,是民间小历的一部分,其名称,由“八干,四维,十二辰”组成。在唐以前,此制曾行用于天象记录中,自唐代起,其用途限于择葬。自公元585年起,“十二辰”制开始出现于天象记录中。由于二十四时制也有“十二辰”名,二者极易混淆。史书中错把“八干”的时间名称妄加改动的实例颇不少见。如果今天想利用古代天象记录进行研究,应对二十四时制有所了解。文中提出了对二十四时制与十二辰制的一些判别方法。
