摘　　要：利用ＥＸＡＦＳ结合ＩＲ等技术对５种含钨原子的多核原子簇的结构进行了研究．提出了一种在原子簇中的吸收原子有不同配位环境时的处理方法．依据表观配位数Ｎｊ′与原子簇中吸收原子总数的乘积即为各种吸收原子数与它真实的配位数Ｎｐｊ乘积之和的原则进行处理．The structures of five multi nuclei tungsten clusters were studied by EXAFS and IR. A method to treat the EXAFS spectra of the samples with absorbing atoms having different neighbours is suggested. The principle is that the product of superficial coordination number N j' and the total number of the absorbing atom in the cluster equals to the summation of the products of the number of the absorbing atom having certain neighbour in the cluster and its real coordination number.Two samples were treated with this method.
