Abstract: A production method and device for multimedia work, and a computer-readable storage medium. The method includes: acquiring a target audio and at least one piece of multimedia information, calculating a matching degree between the target audio and the multimedia information, sorting the at least one piece of multimedia information according to the matching degree in a descending order, assigning top-ranking multimedia information as target multimedia information; calculating the image quality of each image in the target multimedia information, sorting every image of the target multimedia information according to image quality in a descending order, assigning the top-ranking images as target images; and synthesizing a multimedia work according to the target images and the target audio. The method allows the acquisition of high-definition multimedia work in which the video content and background music match with each other, and reduces the time cost and learning cost consumed by users in editing videos.

Abstract: A preparation method and secondary dispersion of monodisperse aminated Nanodiamond colloid solution and its application in cellular biomarking are provided. Preparation method comprise: mixing purified Nanodiamond powder with ammonium chloride and sodium chloride, placing the mixture in a ball mill for dry ball milling, washing the ball-milled mixture with deionized water, and performing ultrasonic dispersion and centrifuging to obtain the monodispersed aminated Nanodiamond colloid solution. Secondary dispersion process comprising: drying aminated Nanodiamond colloid solution to obtain aminated Nanodiamond powder, re-dispersing the powder in DMSO (dimethyl sulphoxide), deionized water, ethanol, DMF (dimethylformamide) or other solvents with ultrasonic or shearing processing. The aminated Nanodiamond has high yield and good monodispersity.
