摘　　要：研究了Glauber动力学下肥皂泡和Voronoi模型上伊辛模型的损伤扩散性质.不考虑面积影响时,肥皂泡和Voronoi结构中平均Hamming距离〈D〉max<0.5,这是由于所用算法造成的,而Glauber动力学下〈D〉max=0.5的结论仍具有一般性.考虑面积影响后,由于网络中孤立自旋增多,使得〈D〉max进一步下降.Damage spreading properties for the Ising model on the soap and Voronoi structures with the Glauber dynamics are studied.It is shown that,if we do not consider the area factor,the results that 〈D〉max0.5 in the soap and Voronoi structures are caused by the algorithm.Under Glauber dynamics,〈D〉max=0.5 is still a general conclusion.After considering the area factor,the further decline of 〈D〉max is due to the increasing of isolated spins in the network.
