摘　　要：利用有效场理论研究了键稀疏混合不同横场伊辛亚铁磁自旋系统的磁学性质．重点给出了平方晶格的磁化曲线．如果键浓度在某一范围内变化，我们发现当不同横场在一限制区域时可获得该系统的补偿温度．我们在文中讨论了不同横场对补偿温度和磁化曲线的影响．并得到有意义的结果．The magnetic properties of the bond - diluted mixed different transverse fields ferri- magnetic spin system is studied by using effective field theory. Particular emphasis is given to the Square lattice for Which magnetizations are obtained. If the hood concentration varies in the certain ranges, we find that the compensation temperature is obtained for values of the different transverse fields in a restricted region. We discuss the influence of the different transverse fields on behaviours of the compensation temperature and magnetization curvrs, and gain reasonable results in the paper.
