Reaching position z_reach was defined as the minimum value of that the molecule had reached; staying time t_stay was defined as the time that the molecule had stayed in the region on the liquid-phase side of the vapor boundary; ξ_in and ξ_out were molecular velocities along the z-direction when the molecule passed through the vapor boundary toward the liquid phase and vapor phase, respectively.
