徐朝俊是徐光启的后裔,其于嘉庆年间所著的《高厚蒙求》一书,是近代早期最重要的科技著作,可以清楚代表当时华人科学家的知识学问。就中西科学文化知识领域立场而言,徐朝俊的近代先驱地位是无可争议的,其时代代表性最值得为后世当作典型标帜。本文从谈天、论地、创制中星表和仿造自鸣钟四个方面,论介此传世之作的精要,以期引起学界必要之关注,而其人其著不致湮没无闻。 Xu Chaojun is a descendant of Xu Guangqi. His book “Gao Meng Mu Qiu” in Jiaqing was the most important scientific and technological work in early modern history, and could clearly represent the knowledge of Chinese scientists of that time. Xu Zhaoshun's modern pioneer position is indisputable on the standpoint of Chinese and Western science and cultural knowledge. Its representativeness of the times is most worthy of future generations as a landmark. This article discusses the essence of this relict from four aspects: talk about heaven and earth, creation of the catalog of middle stars and imitation of the chimes, aiming to arouse the necessary attention of the academic circles.
