Indexing 索引

The journal allows indexing systems, search engines, and other discovery services to crawl, index, and harvest its content and metadata. This ensures that published articles are widely discoverable through academic databases and search platforms. The journal registers Digital Object Identifiers (DOIs) for all published articles through Crossref. Article metadata is deposited with Crossref to support persistent identification, citation, and long-term accessibility of published research.

期刊允许各类索引系统、搜索引擎及学术发现服务对其内容及元数据进行抓取、索引和收录，从而提升文章在学术数据库和检索平台中的可发现性。 本期刊通过 Crossref 为所有文章注册数字对象唯一标识符（DOI），并向 Crossref 存储文章元数据，以支持研究成果的持久标识、引用及长期可访问性。
