The invention provides a deep eutectic solvent and a preparation method and application thereof, the effective components of the deep eutectic solvent are composed of choline chloride and ethylene glycol, the molar ratio of choline chloride to ethylene glycol is 1: 4, the water content of the effective components is 30%, and the deep eutectic solvent can replace an organic solvent to extract total flavonoids from fructus amomi; chemical components capable of distinguishing the varieties of the fructus amomi are determined through quantitative experiments on the fructus amomi flavonoid compounds, serve as differential markers epicatechin, procyanidine B2 and procyanidine B4 for distinguishing the varieties of the fructus amomi and have very high antioxidant activity, and H2O2-induced GES-1 cell oxidative stress is relieved by removing ROS in cells and up-regulating the level of SOD and GSH-Px.

The utility model provides a trunk cover plate arrangement structure and a vehicle, and the trunk cover plate arrangement structure comprises a plate body and a supporting assembly which are arranged in a trunk; the plate body has a floor state in which the plate body is laid on a storage tray at the bottom of a luggage case and a table plate state in which the plate body is supported in the middle position in the height direction of the whole vehicle; the supporting assembly supports the plate body in the table plate state. According to the trunk cover plate arrangement structure, the internal space of the trunk can be reasonably used, the daily storage requirement can be met, the different use requirements such as office work or layered article placement of a user can be met, and therefore the vehicle quality and the market competitiveness can be improved.

The present invention discloses a high-pressure saturated steam power generation and heating system for copper smelting process applied to the field of pyrometallurgical copper smelting, wherein the steam inlet is connected to a steam pressure reducing valve, a steam-water separator, a first medium-pressure heater and a first medium-pressure steam turbine in sequence, and the first generator is driven to generate electricity through a first reduction gearbox, the main steam outlet of the first medium-pressure steam turbine is connected to a heating channel, the heating steam inlet of the first low-pressure heater, the heating steam inlet of the second low-pressure heater and the heating steam inlet of the second medium-pressure heater, the main steam outlets of the first low-pressure heater, the second low-pressure heater and the second medium-pressure heater are respectively connected to the main steam inlets of the first low-pressure steam turbine, the second low-pressure steam turbine and the second medium-pressure steam turbine and drive the second generator through a second reduction gearbox. The system ensures the reasonable allocation of resources, reduces the corrosion damage of the operating structure during operation, and provides a guarantee for the stable working effect of the system structure.

The application relates to a method for synthesizing DMF by electro-reducing carbon dioxide and dimethylamine, and belongs to the technical field of green organic synthesis. x The application relates to a method for synthesizing DMF by electro-reducing carbon dioxide and dimethylamine, and belongs to the technical field of green organic synthesis. The catalyst is used for the electro-catalytic C-N coupling reaction of dimethylamine and carbon dioxide, and DMF is efficiently synthesized under mild conditions. The catalyst has the advantages of rich active sites, high mass transfer efficiency and good stability, does not need to use a noble metal catalyst, and has the characteristics of low cost, environmental friendliness and easy scale production.
