摘　　要：以富勒烯为研究对象,探索地下含水层中的高渗透层区对富勒烯迁移分布的影响和富勒烯在非均质饱和多孔介质中的运移规律。结果显示,高渗透层区为富勒烯纳米材料的迁移提供了优先传播路径;高渗透层区吸附的富勒烯浓度S均比周边背景饱和介质上的低;6个观测点对应的水相富勒烯浓度值中最高的观测点位于最高渗透层。By taking fullerene as the research object,this paper explores the influence of high permeable zone in underground aquifer on the migration and distribution of fullerene and the migration law of fullerene in heterogeneous saturated porous media.The results show that the high permeable zone provides a preferential path for the migration of fullerenes.The concentration of fullerene adsorbed in the high permeability layer is lower than that in the surrounding background saturated medium,and the concentration of the observation point located in the highest permeability layer is the highest in the water phase among the six observation points.
