This paper investigates the entanglement of a two-qutrit Heisenberg XXX chain with nonlinear couplings under an inhomogeneous magnetic field. By the concept of negativity, we find that the critical temperature increases with the increase of inhomogeneous magnetic field b. Our study indicates that for any ｜K｜〉｜J｜, or ｜K｜〈｜J｜ entanglement always exists for certain regions. We also find that at the critical point, the entanglement becomes a nonanalytic function of B and a quantum phase transition occurs.

The significance of the issuance of the Draft Regulation on Museums ＆ that it is the first national legal document about museums. That is to say, China, for the first time, defines the legal status, nature, missions and standards of museums. This document covers such work as the establishment,fiscal policies, tax-cut policies, termination, research and administration of museums. China ＇s museum is now developing under the rule of law.
