Abstract: The present application discloses a thermally insulating aerogel vacuum composite panel and a preparation method thereof. The preparation method includes the following steps: (1) mixing TEOS solution and a metal particle, adding a hydrophobic agent, mixing, adding ammonium trifluoroacetate solution dropwise until completely gelating to obtain a metal aerogel precursor; (2) adding the metal aerogel precursor into an acid replacement solution for replacement for 1-24 h to obtain a gel; (3) washing the gel with deionized water to obtain a neutral gel; (4) soaking the neutral gel obtained in step (3) in a first organic resin solvent; (5) pouring the neutral gel into a substrate with honeycomb structure, and aging for re-gelating to obtain a modified panel; (6) drying the modified panel to obtain a honeycomb panel; and (7) aging the honeycomb panel at room temperature for 1-24 h to obtain the vacuum composite panel.

Abstract: Disclosed is a method for removing an antibiotic resistance gene by using ionizing radiation, wherein same comprises treating antibiotic-microorganism residues using ionizing radiation to destroy the DNA of microbial cells, thereby realizing the effective removal of the resistance gene, and same can simultaneously degrade residual antibiotics, wherein the ionizing radiation is performed using gamma rays or a high energy electron beam generated by an electron accelerator. The radiation in the method can be performed at room temperature and has broad application prospects in the environmental field.

Abstract: Provided is a vehicle generator control method. An engine ECU controls the generator according to an operating condition of the engine, and the control process is as follows: when the engine ECU determines that the engine is in a starting condition, the engine ECU controls a generator separately excited loop to be disconnected, so that the generator does not generate electricity; and when the engine ECU determines that the engine enters an idling condition, the engine ECU controls the generator separately excited loop to be closed, so that the generator is started to generate electricity, and after the generator is started to generate electricity, the generator carries out normal electricity generation until the engine stops operating. Through the vehicle generator control method, the starting load of the engine can be effectively reduced, and cold starting capacity is improved. Also provided is a vehicle generator control system.
