Historical notice (2017): the following records preparations for the Journal Club section at the time.
During PhDSciNet's early preparations for the Journal Club section, we would introduce a new area of content: PhDSciNet Journal Club.
The Journal Club section presents the core findings of scientific articles already published in professional journals as brief reports of no more than 500 Chinese characters. It also includes links to the original articles so interested readers can explore them in depth. Through PhDSciNet, more readers and scholars can learn about your research, expanding its reach and encouraging exchange and collaboration.
The Journal Club section helps more colleagues learn about the latest international developments in their fields and makes it easier for researchers in China and abroad to find one another's work, encouraging academic exchange and connections within specialist communities.
At the section's launch, we invited submissions and welcomed contributions describing research that had already been published. Submissions at the time were made through the original website's submission channel.
The text was recovered from a local Word manuscript of the same work. The final text published on the original site has not yet been obtained for comparison, so this version may differ from the one published at the time. The historical date and original title are retained from the original site's index.
Editorial note: On October 10, 2026, the announcement was restored from the final view of the Word manuscript. Private contact details were removed, and relative dates and the old submission channel were explicitly identified as historical information.
