左侧知识地图 · 右侧 MSC 分类树
本站的数学知识分类，主要参考主流的数学学科分类体系MSC（Mathematics Subject Classification）2020 版，兼顾了美国、中国、德国数学手册、数学指南等工具书的分类体系；同时，按“数量、结构、空间、变化、应用”五大主题做面向大众的知识点分类，应用类知识点放在其他四类主题的交叉位置，体现数学与科学、工程、社会的联系。这样既方便大众建立数学学科整体印象，也为有学术需求者提供了严谨的定位编码。 The classification of mathematical knowledge on this site mainly follows the MSC (Mathematics Subject Classification) 2020, while also taking into account the classification systems of American, Chinese and German mathematical handbooks, mathematical guides, and other reference works. At the same time, it reorganises knowledge into five broad themes for the general public — Quantity, Structure, Space, Change, and Application — with applied topics placed at the intersections of the other four themes, reflecting the connections between mathematics and science, engineering, and society. This makes it easy for most people to form an overall impression of maths, while also providing rigorous locational codes for those with academic needs.
