This paper discusses the critical behaviors and magnetic properties of the spin-1 bond and crystal field dilution Blume-Emery-Griffiths (BEG) model on simple cubic lattice within the framework of effective field theory (EFT).

• 本文在有效场理论的框架内，基于简立方晶格讨论了自旋为1的键和晶场稀疏Blume-Emery-Griffiths(BEG)模型的临界行为和磁学性质。
