The invention relates to a method for reducing hydraulic resistance borne by machines and objects during movement in fluid. When the machines and the objects move in the fluid, the fluid can accumulate at some parts of the machines and the objects, and form high pressure areas. The resistance at the parts is also larger than that at other parts, and form resistance accumulation areas. According to the method disclosed by the invention, disturbance fluid jets are formed in the parts where the resistance to the machines and the resistance to the objects are concentrated, and disturbance fluid is directly blown to the accumulated fluid from the jets, so that the accumulation of the fluid is reduced as possible. The spraying direction of the disturbance fluid and the moving direction of the disturbance fluid are the same or an inclined angle is formed between the spraying direction of the disturbance fluid and the moving direction of the disturbance fluid, as shown in the figure. According to the different shapes of the machines and the objects, the number of the jets can be one, and a plurality of the jets can also be combined and used in a certain distribution type. The disturbance fluid can be the same as fluid surrounding the machines and fluid surrounding the objects, and can also be different from the fluid surrounding the machines and the fluid surrounding the objects, so that the resistance borne by the machines and the resistance borne by the objects during movement in the fluid are obviously decreased.
