Abstract
Provided are an object surface structure for reducing fluid resistance and rectifying fluid, and a preparation method. The surface structure includes a basic surface of an object, arc protrusions formed by a plurality of cambered surface-shaped protrusions are distributed on the basic surface in an array; a rotatable object with an cambered surface in the pit on the basic surface is exposed to the cambered surface outside the pit to form a rotatable arc protrusion; or an cambered surface-shaped object fixed on the basic surface or an arc-shaped protrusion integrated with the basic surface forms a fixed arc protrusion; and the object surface structure provided with the plurality of arc protrusions forms an arc protrusion surface structure. With the application, the purposes of improving moving efficiency, reducing energy consumption of advancing apparatuses, improving advancing efficiency, reducing noise, reducing resonance and improving controllability of a moving object are achieved.
