人类动力学近6年来经历了蓬勃的发展。为了验证和探索艺术创作的人类动力学普遍规律,对徐悲鸿、丰子恺、刘海粟3位著名近代画家的创作进行了统计调研。所得到的创作间隔时间分布规律遵从幂函数,与已知的人类在通信、访问网络、图书借阅、音乐或电影点播等表现出的规律定性相同。3个画家分布幂律的幂指数相同,均为2.14,与科学家、文学家的幂指数规律有较大差异,表明画家创作行为既遵从人类行为的普遍规律,又有自身的特征。此外,建议使用画家每年作品数目数据的“包络线”(距离创作数上升或下降过程中每次振荡达到的高点最近的光滑曲线)及其构成的画家创作高峰的形状与个数,描述画家个体创作规律随个人遭遇的差异。这一统计方法原则上可推广到其他人类行为的研究领域。

In recent six years, the study of human dynamics has experienced a flourishing development. In order to verify and explore the universal human dynamics rules of artist creations, a statistical investigation on the creations of three famous artists (Xu Beihong, Feng Zikai, Liu Haisu) is performed. The results show that their interevent time distributions obey the power law as in a qualitative agreement with the known human dynamics rules in communication, visit to networks, borrowing books and order programme of movie or music. The power law exponents of the three artist interevent time distributions are exactly the same. The value is 2.14, largely deviated from those of scientist and writer interevent time distributions in literature, which indicates that while the artist creation activities do obey the universal rules of human behaviors, they have their own characteristics. It is proposed to use the so-called "enveloping curve" of the data, including the number of the works an artist created in a year, as well as the shape and the number of the creation fastigiums, in an enveloping curve form, to describe the differences of artist individual creation rules due to their personal experience. An enveloping curve is defined as a smooth curve nearest to all "higher points", to which each oscillation of the work number an artist created in a year reaches during a rising or falling process of the creation. In principle, this statistical description suits the studies of other human behaviors.
