| 摘 要： | 为了科学评定国外职业医学核心期刊，以指导有关国外信息的合理引进，本文运用计算机技术，以目前国际上含职业医学内容的最具权威的五种文摘类光盘为引用源，试用经典的布拉德福图像法，分析其中的职业医学文献的分布特点。结果发现ＮＩＯＳＨＴＩＣ光盘的职业医学文献分布最为完全，以累计文摘量划定其职业医学核心期刊区的百分比约为５０％，核心期刊为４０种，但由于布拉德福图像精确度尚不够高，故如何运用更合理的数学推导法确定国外职业医学核心期刊，尚待进一步研究 |

| Abstract: | In this study, the authors wish to identify the foreign core journals in the field of occupational medicine scientifically in order to guide the reasonable introduction of advanced information abroad. For this aim, the five authoritative CD ROMs concerned in the world were cited and typical Bradford Documentation Distribution Curve was applied, in which the distributive characteristics of occupational medical literatures were shown. After determined,it is indicated that CD ROM NIOSHTIC has the most complete distribution of documentation among five discs. Moreover, based on the curve, the percentage of core journals zone of NIOSHTIC is calculated as about 50% according the accumulation of Abstract s and number of core journals is 40. However,considering that the accuracy of determination in the curve method is not ideal, the mathematical derivation of equation to determine the core journals is needed for further study. |
