英文文献摘要：
In this paper we propose a ??scaling-based?? empirical approach to assess the scientific performance of heterogeneous academic disciplines. It relies on the idea that if we take into account for their two main sources of heterogeneity, the bibliometric distributions of different academic fields can be superimposed and collapse to a unique master curve by a single scaling parameter. By using data on the scientific production of around 2,500 scholars of the university of Rome ??La Sapienza?? from the Web of Science (WoS) over 2004?±2008 we i) demonstrate the existence of a master curve; ii) determine the scaling factors which are the cornerstone to compare different academic fields; and iii) show that the master bibliometric distribution follows a Log-normal law.

在本文中，我们建议采用一种scale - baseda?实证方法来评估异质学科的科学绩效。它依赖于这样一种想法:如果我们考虑到它们的异质性的两个主要来源，不同学术领域的文献计量分布可以通过单一的标度参数叠加和崩溃到一个独特的主曲线。通过使用来自科学网络(WoS)的罗马大学(university of Rome A - La SapienzaA)约2500名学者在2004A±2008年间的科学成果数据，我们i)证明了主曲线的存在;二)确定尺度因子，作为比较不同学术领域的基石;(3)表明主文献计量分布遵循对数正态分布规律。
