An earphone box, an earphone and a computer-readable storage medium are also disclosed.

Abstract: Disclosed are an integrated method and an integrated system for resource recovery of source-separated urine. The integrated method for resource recovery of the source-separated urine includes: mixing the source-separated urine with an alkali metal peroxysulphate to obtain a mixture, and subjecting the mixture to evaporation-concentration by heating to obtain condensed water and a liquid compound fertilizer, where the liquid compound fertilizer includes urea, a phosphorus salt, and a potassium salt.

Abstract: This disclosure relates to a manufacturing method of a vapor chamber that includes the following steps. Form a containing space and a flow channel on a first cover. Place a second cover on the first cover, such that the first cover and the second cover together form a chamber at the containing space of the first cover and form a passage at the flow channel of the first cover. Enlarge part of the passage so as to create a circular passage portion and a flat passage portion in the passage. Insert a degassing tube into the circular passage portion of the passage. Draw gas from the chamber and fill working fluid into the chamber via the degassing tube. Seal a joint between the chamber and the flat passage portion by a resistance-welding process. Cut off parts of the first cover and the second cover that surround the passage.

Abstract: Disclosed are a nucleic acid functionalized metal nanoprobe and a preparation method therefor; according to the probe, metal cations with desirable biocompatibility are mixed with exogenous deoxyribonucleic acid (DNA) or ribonucleic acid (RNA) molecules to generate a DNA or RNA composite nanostructure; co-incubating is performed with a pathogenic microorganism, the composite nanostructure enters pathogenic microorganism cells through electrostatic adsorption, and unique microenvironment of high-level oxidizing and reducing substances possessed by the pathogenic microorganism is used to promote in-situ synthesis of the intelligent biological probe; accurate targeted labeling and real-time rapid detection of the pathogenic microorganism are achieved, and the probe is used for targeted intervention of infectious diseases such as lung infection, intestinal infection and influenza; combined with physical interventions such as photoelectricity, magnetocaloric effect, near infrared, multi-modal real-time dynamic and
