摘　　要：材料的快中子溅射性能直接关系到裂变和聚变反应堆材料的选择。在测量得到的（ｎ，２ｎ）、（ｎ，α）、（ｎ，ｐ）和（ｎ，ｎｐ）核反应的快中子溅射产额的实验数据基础上，结合理论计算结果，得到了１ 个适合于计算上述４ 种核反应的约化溅射产额的修正的理论计算公式。The sputtering performance of materials induced by fast neutrons is of vital importance to the selection of the materials for fission and fusion reactors. Based on the experimental data of fast neutrons sputtering yields obtained from (n,2n),(n,α),(n,p) and (n,np) reactions and combined the results of theoretical calculation, a revised theoretical calculating formula is deduced with which one can calculate the reduced sputtering yields for four reactions.
