数字对象标识符 (DOI)

A Digital Object Identifier (DOI) is a unique alphanumeric string assigned to a digital object, such as a research paper or dataset, to provide a permanent link to its location on the internet. It facilitates the efficient retrieval and citation of digital content, ensuring that researchers and practitioners can easily access and reference the work. By standardizing the identification of digital objects, DOIs enhance the integrity and accessibility of scholarly communication and innovation in product design and research.
