| 摘 要： | 利用《中国引文数据库(CCD)》作为样本统计源，分别对相同时间段不同学科、同一学科不同时间段的期刊h指数与载文量(n)、篇均被引量(p)进行统计与曲线回归，曲线回归结果良好，通过对《中文社会科学引文索引(CSSCI)》统计数据回归，进一步证实曲线方程的存在，并根据回归结果分析统计时间段差别对曲线系数的影响及曲线变化的基本规律。

| Abstract: | Using data from the CCD(China Citation Database), this paper estimates the OLS non-linear regression of periodical h index on the numbers of articles published (n) and times of per article cited (p) belonging to same period of time-disparate disciplines and same discipline-disparate period of time, which is statistically significant. Furthermore, it estimates the OLS regression of same variables using data from CSSCI, and testifies the existence of the non-linear function. Based on the regression results, it analyzes the influences on the curve coefficients and the basic norms of curve change due to time difference. |

| Keywords: | h-index times of per article cited numbers of articles published non-linear model norms of change |
