摘要
我们证明异质索引，它被胡和王建议[Physica A 387 (2008 ) 3769 ] ，能被用来描述分享的合作或比赛获得分布的不同，它为理解一个合作 / 比赛系统的动力学是很重要的。在分发参数和异质索引之间的一种分析关系被导出，它在对实验结果的好同意。我们也，在分发参数之间的关系能是经分解的表演从所谓的 ZhangChang 导出的理论、实验的分析当模特儿[Physica A 360 (2006 ) 599；383 (2007 ) 687 ] 。这强烈建议可能性创造一个一般动态合作 / 比赛模型。
We show that the heterogeneity index, which was proposed by Hu and Wang [Physica A 387 （2008） 3769], can be used to describe the disparity of the cooperation sharing or competition gain distributions, which is very important for understanding the dynamics of a cooperation/competition system. An analytical relation between the distribution parameters and the heterogeneity index is derived, which is in good agreement with the empirical results. Our theoretical and empirical analyses also show that the relation between the distribution parameters can be analytically derived from the so-called Zhang-Chang model [Physica A 360 （2006） 599; 383 （2007） 687）. This strongly recommends a possibility to create a general dynamic cooperation/competition model.
