摘要：NOVELTY - The method involves selecting equal diameters of transparent or half-transparent particles in a geometrical center. A core is rotated as a granule. The transparent or half-transparent particles are arranged in a two-dimensional image sequence. Movements of the transparent or half-transparent particles are captured by high speed cameras (2-1, 2-2). A reconstructed particle three-dimensional motion trail is obtained through the two-dimensional image sequence. Self-rotating speed of the transparent or half-transparent particles is obtained in a rotational flow field. USE - High-speed liquid rotational flow field particles rotation photographing method. ADVANTAGE - The method enables improving liquid rotational flow field particles rotation shooting efficiency. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is also included for a high-speed liquid rotational flow field particles rotation photographing device. DESCRIPTION OF DRAWING(S) - The drawing shows a schematic view of a high-speed liquid rotational flow field particles rotation photographing device.'(Drawing includes non-English language text)' Liquid storage tank (1-1) Vortex pump (1-2) Micro-rotational flow device (1-5) High speed cameras (2-1, 2-2) Cold light source (3)
