本文对最大引文年限进行了进一步的研究,并通过广泛的统计数据证明了用它测度科学交流的社会必要劳动时间的合理性及重要意义,从而建立了科学劳动与物质生产劳动的可比性测度. In this paper, we further study the maximum number of quotations and prove the rationality and significance of the socially necessary working time to measure scientific exchange through a wide range of statistical data, so as to establish a comparability measure between the labor of science and that of material production.
