Abstract

In a 1836 publication on astronomical refractions, Biot (1774–1862) introduced a change of variable, which would become classical, in order to numerically calculate the refraction integral. This change renders well-behaved the integral, in the case when a celestial body is seen on the astronomical horizon. Biot also proves a beautiful theorem, giving the local vertical angular magnification on such horizon. In addition, he comments on various atmospheric models.

Biot定理和Biot–Auer–Standish变量变化：历史评论

在1836年出版的一本关于天文折射的出版物中，毕奥（1774-1862）引入了一个变量的变化，这将成为经典，以数值计算折射积分。在天文地平线上看到天体的情况下，这种变化使积分表现良好。毕奥还证明了一个美丽的定理，给出了在这样的地平线上的局部垂直角放大率。此外，他还评论了各种大气模型。在线发布：2023年2月21日，发布日期：2023月11日

期刊介绍： The Comptes Rendus - Physique are an open acess and peer-reviewed electronic scientific journal publishing original research article. It is one of seven journals published by the Académie des sciences. Its objective is to enable researchers to quickly share their work with the international scientific community. The Comptes Rendus - Physique also publish journal articles, thematic issues and articles on the history of the Académie des sciences and its current scientific activity. From 2020 onwards, the journal''s policy is based on a diamond open access model: no fees are charged to authors to publish or to readers to access articles. Thus, articles are accessible immediately, free of charge and permanently after publication. The Comptes Rendus - Physique (8 issues per year) cover all fields of physics and astrophysics and propose dossiers. Thanks to this formula, readers of physics and astrophysics will find, in each issue, the presentation of a subject in particularly rapid development. The authors are chosen from among the most active researchers in the field and each file is coordinated by a guest editor, ensuring that the most recent and significant results are taken into account. In order to preserve the historical purpose of the Comptes Rendus, these issues also leave room for the usual notes and clarifications. The articles are written mainly in English.
