Abstract: A control method for an arthroplasty surgical robot includes: capturing a bone image, transmitting the image to a computer system, and acquiring image data of a bone; selecting a suitable prosthesis model and placing it on a diseased joint for matching, wherein the overlapping part between the model and the bone is the part that needs to be removed and replaced; mounting signal sources; capturing a bone image again, including the signal sources and the joint part; establishing a coordinate system using the signal sources as the origin, and calculating and memorizing an interface between the model and the bone overlapping part and the coordinates of the interface in the coordinate system; and receiving the coordinates by a surgical robot, and obtaining the positional coordinates by the surgical robot of a part of the diseased joint that needs to be removed, and performing a surgical operation by the surgical robot.

Abstract: A vanadium-chromium electrolyte, a method for preparing the same, and a redox flow battery composed thereof are provided. The vanadium-chromium electrolyte includes active substances and a free acid, the free acid acts as a proton conductive agent after ionization, and the active substances contain at least vanadium ions and chromium ions. The present disclosure further provides the method for preparing the vanadium-chromium electrolyte, which includes the following steps: dissolving a vanadium compound with a free acid, and obtaining a mixed solution of the free acid and vanadium ions through filtering; electrolytically reducing vanadium to an average valence state of 3.5 to 4 valence; adding a chromium compound, dissolving through stirring, and implementing a filtering; and adding pure water and an auxiliary reagent to adjust concentration, and preparing the vanadium-chromium electrolyte.
