论文摘要
一个基于用于制定动态模型的想法的两旋链系统，该模型模拟了一个社会中传播的意见过程，人们研究了四种社会态度之一[Physica A 351，593（2005）]。该模型是由链条制成的，在每个位置都有两种旋转S和V的链条，并与Insite相互作用〜M0相结合，并以不同的方式与最近（NN）和下一（NNN）邻居相互作用。仅分析了S旋转的NN相互作用以及V旋转（ACLS模型）的NN和NNN相互作用的一维模型。使用线性重归其化组（LRG）计算特异性热和相关函数对温度和〜m0的依赖性。考虑了Insite和NNN相互作用的作用。 ACLS模型定义了描述社会中观点传播的动力学模型的稳定状态的实用性，该模型在两个领域中代表了对自由水平的四种不同态度：讨论了个人和经济。可以指出的是，组织现代社会的困难可能是由于这两个领域之间的内部局势造成的。 1
A two-spin system based on the idea used to formulate the dynamical model simulating the process of opinion spreading in a society, where people adopt one of the four social attitudes [Physica A 351, 593 (2005)] is studied. The model is made of chains with two species of spins S and V at each site coupled by an insite interaction ~M0 and interacting in different way with nearest (NN) and next-nearest (NNN) neighbors. The one-dimensional model with only NN interaction of the S spins and both NN and NNN interactions of the V spins (ACLS model) is analyzed. Using the linear renormalization group (LRG) the dependences of the specific heat and correlation functions on temperature and ~M0 are calculated. The roles of the insite and NNN interactions are considered. The usefulness of the ACLS model to define stable states of the dynamical model describing opinion spreading in a society, which members represent four different attitudes to the level of freedom in two areas: personal and economic is discussed. It is pointed out that the difficulties in organizing modern societies can result from an internal con ict between these two areas. 1
