A method of reducing the object-traveling resistance includes the steps of forming a plurality of small cavities (31) on the whole or at least a portion of an object skin (20) by a non-destructive measure, and producing a plurality of small vortexes (33) at the object skin (20) to form a thin turbulent boundary layer (30) when a fluid (40) passes through the plurality of small cavities (31), for achieving an advantageous interference to a turbulence of the fluid (40) at the object skin (20), such that a portion of fluid (40) is not in contact with the object skin (20), and a viscous drag acting on the object skin (20) is reduced to extend a wake (41) and reduce a drag force of the wake (41). The aforementioned mechanism can reduce the object-traveling resistance to provide a faster traveling speed and a big moving power of the object (10).
