被《汉书·艺文志》列入“杂家”的《吕氏春秋》不是天文历法专著,但是,从书中,我们又无时无刻不感受到天文历法的存在。从它的编排到它的内容,我们都能发现天文历法的深刻影响,都能体察到著者对天文历法知识体系的精通与娴熟。 “Lu's Spring and Autumn”, which was listed in “Han Yi Yi Wen Zhi” as “Miscellaneous”, is not an astronomical calendar monograph. However, from the book, we also feel the existence of astronomical calendar all the time. From its orchestration to its contents, we can all discover the profound impact of the astronomical calendar, and we can all realize that the author is proficient and adept at the system of astronomical calendar knowledge.
