We derive the analytic expression of the concurrence in the quantum Heisenberg XYZ model and discuss the influence of parameters J,Δ and Γ on the concurrence.By choosing different values of Γ and Δ,we obtain the XX,XY,XXX and XXZ chains.The concurrence decreases with increasing temperature.When T→0,the concurrence reaches its maximum value 1,i.e.the entangled state,|ψ>=√2/2(|01>-|10>),is maximum entanglement.For the XXZ chain,when Γ→∞，the concurrence will meet its maximum value Cmax=sinh(1/T)/cosh(1/T).
