摘　　要：依据放射性核素237 Np在浙江红土饱和土柱中浓度分布,采用单纯形优化算法对237 Np在饱和浙江红粘土中的迁移参数进行了优化,得到的目标函数χ2为0.45,而用实验测得的迁移参数计算得到的目标函数χ2为0.75。结果表明:迁移参数的优化结果与实验测量结果有很好的一致性,可直接依据核素浓度分布采用优化方法确定核素迁移参数。According to the concentration distribution of radionuclide 237 Np in the saturated soil column of red clay from Zhejiang Province,the objective functionχ2 was obtained as 0.45 after simplex optimization algorithm was adopted to optimize migration parameters,while the objective functionχ2 was calculated as 0.75 with experimental migration parameters.The result showed that there exists a good consistency between the optimization result of migration parameters and experimental measurement results.So,the optimization method can be adopted directly to confirm the migration parameters for nuclides according to nuclide concentration distribution.
