中国化学期刊的出版时差和超前引用分析

Study on the Time-lapse of Chinese Chemical Journals and the Appearance of "Citation in advanc" as its Consequence

利用'中国化学期刊文献引文数据库'对我国化学基础研究领域的38种重要期刊进行了期刊出版周期与论文发表时差的统计,并从'超前引用'现象人手,分析了编辑出版速度对文献交流的影响.对我国编辑出版速度缓慢的原因也做了简要的分析.

Using the database establised for 38 Chinese Core journals in the field of chemistry a statistical analysis of the publication frequency and time delay for these journals has been carricd out. With the consideration of appearing 'Citation in advance' the authors discussed the influence of the comparatively low publication frequency on the communication of chemical information. The reasons causing the lower frequency of journal publication are briefly inquired as well.
