对复杂网络的一个长期的普通信仰是那，大多数连接节点是最有效的 spreaders。然而，真实世界的复杂网络上的最近的调查证明最有影响的 spreaders 是有最高的 k 壳价值的那些。它是著名的，许多真实世界的复杂网络让规模释放(SF ) ，小世界(SW ) 性质，因此一般来说人工的 SF， SW 以及随机联网的有影响的 spreaders 的鉴定将是更多的呼吁。这研究发现那人工嗯并且 SW 网络，度是比在预言传播的结果的 k 壳更可靠的。为人工的 SF 网络，然而，k壳比度和 betweeness 显著地可靠，它显示四个最近调查的真实世界的网络[ Kitsak M ， Gallos L K ， Havlin S ， Liljeros F ， Muchnik L ， 斯坦利·H·E ， Makse H A ，在复杂网络的有影响的 spreaders 的鉴定， Nat 。Phys， 2010， 6：888893 .] 是更类似的放大免费的。而且，调查也显示我们在有规模的网络的最佳的传播策略免费性质。也就是说从 moderate-degree-nodes 开始将是好甚至更多节俭，后来，一个人能与从中心开始导出粗略地类似的结果。

英文摘要：

A long-term common belief in complex networks is that,the most connected nodes are the most efficient spreaders.However,recent investigations on real-world complex networks show that the most influential spreaders are those with the highest fc-shell values.It is well-known that,many real-world complex networks have scale free（SF）,small world（SW） properties,therefore,identification of influential spreaders in general artificial SF,SW as well as random networks will be more appealing.This research finds that,for artificial ER and SW networks,degree is more reliable than fc-shell in predicting the outcome of spreading.However,for artificial SF networks,fc-shell is remarkably reliable than degree and betweeness,which indicate that the four recently investigated real-world networks[Kitsak M,Gallos L K,Havlin S,Liljeros F,Muchnik L,Stanley H E,Makse H A,Identification of influential spreaders in complex networks,Nat.Phys.,2010,6：888-893.]are more similar to scale free ones.Moreover,the investigations also indicate us an optimal dissemination strategy in networks with scale free property.That is,starting from moderate-degree-nodes will be ok and even more economical,since one can derive roughly similar outcome with starting from hubs.
