摘　　要：在链间耦合中同时计入相邻链相同格点间电子跳跃积分和相邻链次近邻格点间电子跳跃积分，研究了链间耦合对电荷密度和自旋密度分布的影响．结果表明，链间耦合可以导致主链上出现电荷密度波，不同格点间的链间耦合诱导自旋密度在侧基和主链间发生不同的转移．Based on our interchain coupled theoretical model for quasi\|one\|dimensional organic ferromagnet,we took into account the nearest and the next nearest hopping interactions between neighboring chains,to study the charge density wave and the spin density wave along the main chain.The calculated results showed that the interchain coupling results in the transfers of charge density and spin density between the main chain and the side radicals of the two coupled chains.
