This invention discloses a method for the stepwise extraction of single components from high-purity insoluble dietary fiber, belonging to the field of chemical separation and extraction technology. The method specifically includes: (1) Lignin extraction: reacting high-purity insoluble dietary fiber with a eutectic solvent at high temperature, filtering to obtain filtrate and precipitate one, and then concentrating, settling, washing and drying the filtrate to obtain lignin; (2) Hemicellulose extraction: adding acetone to precipitate one and stirring and centrifuging to obtain precipitate two; then adding alkaline solution to precipitate two, stirring and settling to obtain precipitate three and supernatant; then subjecting the supernatant to alcohol precipitation and freeze-drying to obtain hemicellulose; (3) Cellulose extraction: washing and freeze-drying precipitate three to obtain cellulose. Through the above method, the stepwise extraction of single components from insoluble dietary fiber can be achieved with high purity; in addition, the raw materials used are inexpensive, and waste can be utilized at high value, reducing resource waste.

This invention relates to a method for power grid cross-section quota reasoning and early warning based on knowledge graph distributed representation, comprising the following steps: Step 1, inputting a dataset from an intelligent dispatch control system; Step 2, performing data preprocessing; Step 3, extracting knowledge from the cross-section quota information in Step 2; Step 4, linking three types of entities in the extracted knowledge according to prescribed event relationships to form sub-knowledge graph units, and establishing a cross-section quota knowledge graph by connecting the various sub-units; Step 5, based on the knowledge extraction model established in Step 3 and the knowledge graph generated in Step 4, reasoning out the stable quota value of a specific power grid cross-section through intelligent cross-section quota reasoning; Step 6, providing early warning of exceeding the limit based on the stable quota value of the power grid cross-section derived in Step 5. This invention can improve the efficiency of power grid steady-state cross-section monitoring and the level of intelligent early warning, ensuring the safe and stable operation of the power grid.

This application relates to the field of in-vehicle air purification technology, and provides a method, apparatus, electronic device, and readable storage medium for purifying in-vehicle air. The method includes: when a pet is detected in the vehicle, controlling the air purifier of the vehicle to adjust to a first preset level; acquiring the concentration of pet hair in the air inside the vehicle; and when the concentration of pet hair is greater than the first preset concentration, controlling the air purifier to adjust to a second preset level; wherein the purification intensity corresponding to the second preset level is greater than the purification intensity corresponding to the first preset level. This application solves the problem in the prior art where manually adjusting the air purifier when a pet enters the vehicle results in insufficient timely purification of the in-vehicle air.
