摘要：
The effects of alternating interaction on the bipartite entanglement are considered in an antiferromagnetic Heisenberg opened chain. Entropy is used to evaluate bipartite entanglement in the system. There are large oscillations between even and odd L-values entropy. The even (odd)-values entropy increases when the length of the subsystem increases. The method of density matrix renormalization-group is applied to obtain logarithmic behavior of entropy.
