In the present article, by using coupling technique, we establish the relation between Ising model and contact process. 本文利用耦合的技巧,建立了Ising模型与接触过程的联系。
With the effective-field theory with correlations, we study the interface phase diagrams of two diluted Ising magnets. The results show that the interface magnetic order appears only in a limited range of the interface coupling. Some typical phase diagrams are presented. 本文用关联有效场理论研究了两稀释伊辛磁体的界面相图.结果表明,界面磁序仅出现在界面耦合有限范围内.本文给出了几种相图。
It's found that the step effect can be produced in the antiferromagnetic coupling system with small number of spins. 通过一维Ising模型及系统能量、自旋组态的研究,发现小自旋数目的反铁磁耦合系统是产生M-H阶梯效应的根本原因。
