Abstract: A composite positive-electrode material includes LMFP and LFP. The LMFP has a primary particle size in a range of 20 nm-200 nm. The LFP has a primary particle size in at least two ranges of: 100 nm-200 nm; 200 nm-350 nm; 350 nm-500 nm; and 500 nm-1000 nm. The primary particle size of the LFP is larger than the primary particle size of the LMFP.

Abstract: A method for scaling the porcelain material of a restoration and the associated machining process is invented, which comprises: establishing a data model of the restoration (S100); dividing the bonding surface or interface between veneer porcelain to be prepared and a restoration substrate into a finite number of element surfaces (S200); establishing the direction coordinate axis on every element surface as its reference axis for setting up a size and a thickness value of veneer porcelain of each element surface (S300); determining and specifying the size and thickness of the veneer porcelain of every element surface according to the preset size and thickness value, and completing the bonding surface by covering it with the veneer porcelain composed of all the element surfaces as scaled with those sizes and thickness values as referred to (S400); generating the outer contour of the veneer porcelain of a clinic restoration (S500).

Abstract: Systems and methods for image correction are provided. The systems and methods may obtain raw data of a target object. The systems and methods may determine, based on the raw data of the target object, a target phase. The systems and methods may generate a first image corresponding to the target phase. The systems and methods may determine, using a preset evaluation tool, an image quality evaluation result of the first image. In response to determining that the image quality evaluation result of the first image does not satisfy a preset condition, the systems and methods may generate a set of corrected raw sub-data of the target object corresponding to the target phase by correcting a set of raw sub-data of the target object corresponding to the target phase. The systems and methods may generate, based on the set of corrected raw sub-data of the target object, a corrected image corresponding to the first image.
