摘要：

General polynomial case of Heisenberg model for spin-1 two- and three-particle clusters is considered on matter of quantum entanglement and its evolution under quantum phase transitions induced by changes of external parameters. Influence of anisotropy parameter on the phase structure and quantum entanglement is studied. The thermal evolution of quantum entanglement is also studied. Some similarities of ground state structures and phase diagrams of quantum entanglement in different planes of external parameters are considered.
