Beschreibung
Zusammenfassung:	The invention discloses a blade based on a bionic shark placoid scale structure and an impeller with the same, the blade based on the bionic shark placoid scale structure comprises a blade body and a plurality of resistance reduction modules, the multiple resistance reduction modules are arranged on at least one side of the blade body, and the multiple resistance reduction modules are sequentially arranged in the extending direction of the blade body; each resistance reduction module comprises a plurality of resistance reduction units, a plurality of protrusions are formed on the outer surface of each resistance reduction unit, a fluid groove is formed between every two adjacent protrusions, and the fluid grooves penetrate through the resistance reduction units in the extension direction of the blade body. According to the blade based on the bionic shark placoid scale structure, the multiple protrusions are arranged on the surface of the blade body, and the fluid grooves extending in the extending direction o
