| 摘 要： | 历史上采用地方时间（如地方视太阳时、平太阳时等）观测和记录的某些天象的时刻，可用于地球自转速率变化的研究．日本在１７—１９世纪间有许多月球朔和望时刻的观测记录．本文简要介绍了其记载情况，探讨了将这些年代较晚的观测资料用于地球自转速率变化研究的可能性．试算结果表明他们对研究此期间地球自转速率的变化可起到积极作用．有必要对他们作更深入的研究．

| Abstract: | Observed and recorded time of some ancient astronomical phenomena in local time,such as local apparent solar time, can be used in the study of the Eachs's rotational variation. There are some tried records of syzygy in Japan in the period of 17th--19th century.In this paper, the observations of syzygy and the possibility that the records arc used in thestudy is investigated. The unital result showed that the records will possibly be significantfor the study and they should be investigated and studied in depth. |
