The invention relates to a method for controlling rising of bubbles in liquid by utilizing a super-aerophilic filament track. According to the invention, the super-aerophilic filament track is fixedlyarranged in liquid through a track support, the surface of the filament track is uniformly covered with a layer of micron-sized gas film, and when bubbles in the liquid are close to the filament track and finally contact with the filament track, the liquid film between the filament track and the bubbles is broken, so that the bubbles are adsorbed, and the bubbles begin to slide under the combinedaction of buoyancy and adhesive force of the silk track; and bubble ascending motion modes and ascending speeds can be regulated and controlled according to different ratios k of the diameter of thebubbles to the diameter of the wire track. By adjusting the diameter and wettability of the wire track, the floating form, track and speed of the bubbles are controlled, the contact line of the controlled bubbles and the wire t
