摘要：

By molecular dynamics simulations, we investigate the microscopic details of the mechanism of spreading. Our data are in agreement with experimental evidence and support the validity of the de Gennes-Cazabat model describing the late stages of spreading. The effects specific to chainlike molecules are also accounted for.
