摘要：
We study the spontaneous wetting of liquid drops on FCC solid substrates using large-scale molecular dynamics simulations By varying the solid lattice parameter, five different drop/solid dynamic systems are investigated It is shown that the results are in agreement with the molecular-kinetic theory (MKT) describing the dynamics of wetting Moreover. it is established that the microscopic parameters resulting from fits using the MKT. the so-called molecular jump frequency at equilibrium and the jump length, correspond to the values that can be estimated directly from the simulations. This agreement strongly supports the validity of the MKT at the microscopic scale
