《化学工程理论》被OUCI开放乌克兰科学索引收录：化工理论研究融入全球开放科学基础设施（Chemical Engineering Theory Indexed by OUCI: Chemical Engineering Theory Research Integrates into Global Open Science Infrastructure）

Abstract：Against the backdrop of the open science movement reshaping the global academic dissemination landscape, Chem-ical Engineering Theory (ISSN 3105-7470, eISSN 3105-7489, CODEN: HGLAA6, DOI prefix: https://doi.org/10.66106/hglaa6, Import Registration Number: G015Z120), a gold open-access Chinese-language bimonthly journal published by Quest Press Limited, has recently been officially indexed by OUCI (Open Ukrainian Citation Index). Developed by the Ministry of Educa-tion and Science of Ukraine and the State Scientific and Technical Library of Ukraine, OUCI is an open access academic search engine and citation database built upon Crossref's Cited-by service and the Initiative for Open Citations (I4OC). It indexes schol-arly literature from all publishers worldwide that use Crossref's citation services. Unlike commercial databases, OUCI adheres to an open, transparent, and non-commercial operational philosophy. The journal focuses on the theoretical foundations and frontier innovations of chemical engineering. All accepted articles undergo rigorous international peer review and are published under the CC BY 4.0 license, making them permanently and freely accessible. Being indexed by OUCI marks the journal's official in-tegration into the global open science infrastructure network. This article, taking into account the journal's positioning, analyzes the practical value of this indexing.
