摘要:

本文试图导出长程相互作用复杂系统系综平均内能的表达式。此外,香农熵假设被用来推导能量的概率分布函数。值得一提的是,能量的概率分布函数可以等价于Tsallis基于非广延熵给出的q-高斯分布。为了验证该模型的现实意义,将其应用于较老的收入制度课题。经典的收入分配是两阶段的,最公认的低收入分配是指数形式,而高收入分配是公认的帕累托幂律分布。概率分布可以解释美国收入数据的整个分布。此外,还可以计算出美国收入系统的内能、熵和温度,呈现出美国近年来的经济危机。相信该模式将得到进一步完善并推广到其他领域。

英文摘要:

In this paper, we attempt to derive the expression of ensemble average internal energy in long-range interaction complex system. Further, the Shannon entropy hypothesis is used to derive the probability distribution function of energy. It is worth mentioning that the probability distribution function of energy can be equivalent to the q-Gaussian distribution given by Tsallis based on nonextensive entropy. In order to verify the practical significance of this model, it is applied to the older subject of income system. The classic income distribution is two-stage, the most recognized low-income distribution is the exponential form, and the high-income distribution is the recognized Pareto power law distribution. The probability distribution can explain the entire distribution of United States income data. In addition, the internal energy, entropy and temperature of the United States income system can be calculated, and the economic crisis in the United States in recent years can be presented. It is believed that the model will be further improved and extended to other areas.
