摘　　要：用平均场近似方法研究了纵场中横向伊辛模型的晶场效应,绘出相图,并计算了纵向磁化、横向磁化和四极柜。The transverse - field and crystal - field effects of the spin - 1 Ising model in the presence of a longitudinal field are studied with the scheme of mean -field approximation ( MFA). The phase diagrams and the other critical properties are investigated. The longitudinal and transverse magnetizations and the quadrupolar moments are calculated.
