摘　　要：用有效场理论研究了二维稀磁Ｉｓｉｎｇ系统的基态磁性质和基态能量．计算了基态时相变点和补偿点随磁原子浓度的变化情况，得到了基态相图．给出了基态时磁化强度曲线，得到和相图自洽的结果，同时还给出了系统基态能量曲线．The ground state properties of the two dimensional diluted mixed Ising ferromagnetic system are investigated within the framework of an effective field theory. The phase diagram in P A P B plane of ground state of z=4 system is given. The magnetization curves and internal energy curves of ground state are given too .
