摘要/Abstract

摘要： 基于界壳理论,将界门的开关作用引入到Logistic模型中,建立了一个新的离散Logistic模型,对模型进行了映射计算,分析了在不同参数下模型的非线性特性,计算得到了若干常定数和循环小数.

关键词: 系统科学, 界壳, Logistic模型, 生命生长

Abstract: The system boundary which plays a role in:Ι defending the existence of the system; and Ⅱ exchanging between the system and its environment is defined as a shell (Jieke).Some basic concepts in Jieke theory are described.Some applications of the theory are presented too, in particular,considering switch function of the gate in system, a new discrete logistical model is established.Mapping calculation for the model was conducted.Then nonlinear features of the model with parameter variation were analyzed and irrational numbers and cyclic small numbers are obtained.

Key words: system science, jieke, logistic model, life growth
