查询词典 sediment-covered

Using environmental radionuclide 210Pb to study the soil erosion and sediment had great application value and potential. When the nuclide was settled on the surface with atmosphere, it was absorbed by the soil particle quickly. The soil erosion rate on the scale of 100 years was traced through the remotion of nuclide in soil and its regular distribution nude.
