摘要：
In this paper, thermal entanglement in three-qubit spin system has been addressed. The results show that spin-spin exchange interaction, the effective external magnetic field, next-nearest-neighbouring interaction have notable effects on the time evolution of the state and thermal entanglement So we can control thermal entanglement by changing the above parameters.
