| 摘 要： | 考虑了泥沙吸附和解吸、沉降和再悬浮对水相和泥沙相核素浓度的影响，根据质量守恒定律、吸附动力学方程和泥沙工程学建立了河流核素迁移的整体模型，进而得到分相模型.运用所得的模型对资江核电站排出的Sr在河流中迁移转化进行模拟，模拟结果表明所建模型基本上能反映Sr在水体中随水-悬浮泥沙-底泥沙的迁移规律.

| Abstract: | Based on the physical migration of water phase and sediment phase nuclide, we take into account the sediment adsorption and desorption of radionuclides, sedimentation and resuspension. We also establish the overall model and separated model of nuclide migration. The numerical simulation is accurate, and basically reflect the radionuclide migration and transformation process in Zijiang River. |
