摘　　要：研究了在饱和水流条件下，花岗岩单裂隙中脉冲注入核素迁移的数学模型，给出了脉冲注入情况下裂隙和岩块中核素浓度分布的解析解；结合裂隙中流出液样浓度的穿透曲线，给出了核素迁移的有关参数，并对影响这些迁移参数的主要因素进行了分析。The mathematical model of radionuclide migration in single fractured granite is studied under saturated flow and pulse injection. The analytical solutions of concentration distribution in fracture and rock matrix are given. By analyzing the breakthrough curves of concentration eluting from single fracture, the relative parameters are obtained. The main factors affecting these parameters are also described.
