Open Access Statement:

Journal Of Henan Normal University (Natural Science Edition)  was established in 1960, and flipped to an open access journal under the CC BY-NC-ND license in 2023. All articles published since the first issue of 2023 are available as open access works. Upon publication, these articles are immediately accessible on the official journal website free of charge to all users. Under the terms of the CC BY-NC-ND license, users are permitted to read, download, copy, distribute, print, search, or link to the full texts of the articles, crawl the articles for indexing, pass them as data to software, or use them for any other lawful aims.

Articles from 1960 to 2022 are published using a non-open access model, and are therefore not open access works. Most of the articles published between 2015 and 2022 are archived on the journal's official website (see Archive), and are available for free full-text download. The remaining past issues are not yet archived on our website, but readers may access them through databases like China National Knowledge Infrastructure (CNKI) at https://www.cnki.net/
