The invention discloses a control method, a control device and an air conditioner. The air conditioner comprises an air outlet panel, the air outlet panel comprises a front air outlet and a lower air outlet, the front air outlet is used for supplying air forwards and is provided with a front air outlet air deflector assembly, and the lower air outlet is opened downwards and is provided with a lower air outlet air deflector assembly; the front air outlet air deflector assembly and the lower air outlet air deflector assembly operate independently. The front air outlet air deflector assembly comprises an outer side air deflector assembly and an inner side air deflector assembly which operate independently; the control method comprises the steps that the outer side air guide plate assembly, the inner side air guide plate assembly and the lower air outlet air guide plate assembly are controlled, so that a multifunctional air supply mode is achieved through cooperation of the front air outlet and the lower air outlet. According to the scheme, the problem that a user feels cold in legs and feet due to the fact that downward air supply is difficult and particularly hot air conduction is difficult can be solved, the conduction angle of hot air can be controlled, the selectivity of the user is more, and therefore the carpet type heating effect can be achieved.

The utility model relates to the technical field of lamp equipment, in particular to a stage lamp with double lamp panels, which comprises a lamp holder, and a first lamp panel, a second lamp panel and a rotating device for driving the first lamp panel and the second lamp panel to rotate are sequentially arranged on one side of the lamp holder. The first lamp panel comprises a first rotating disc and a plurality of first lamp strips arranged on the peripheral side of the first rotating disc. The second lamp panel comprises a second rotating disc and a plurality of second lamp strips arranged on the peripheral side of the second rotating disc. The rotating device drives the corresponding first lamp strip and the second lamp strip to rotate through the first rotating disc and the second rotating disc. The first lamp panel and the second lamp panel are arranged on the lamp holder, the two lamp panels are matched to emit light to form more complex and diverse light effects, the structure is compact, and the cost can be saved. And the rotating device drives the first lamp panel and the second lamp panel to rotate, so that the created light effect is better, the selectivity is more, and the lamp is suitable for more scenes.

The present application provides a vehicle screen control method, device and vehicle, which relates to the field of vehicle-mounted display. The method includes: in response to a picture quality configuration operation on a first screen in a vehicle, obtaining a target picture quality configuration parameter of the first screen; determining a risk parameter of the configuration operation; wherein the risk parameter is used to indicate whether the picture quality configuration operation has a risk; based on the target picture quality configuration parameter and the risk parameter, controlling the picture quality parameter of the target screen in the vehicle; wherein the target screen includes the first screen. The solution can avoid the influence of the picture quality configuration operation on the screen in the vehicle and ensure the driving safety of the vehicle.

The application provides a wireless network access method, device and electronic equipment. The method comprises: in the case of accessing a first network in a first frequency band, determining at least one candidate network in a second frequency band, the frequency of the second frequency band being less than the frequency of the first frequency band; determining a second network meeting a preset condition from the at least one candidate network, the preset condition indicating that a target matching degree between the first network and the second network is greater than a matching degree threshold, and the target matching degree is determined based on a service set identifier dimension matching degree, a basic service set identifier dimension matching degree and a signal strength dimension matching degree. The application provides a more adaptive wireless network access scheme.

The present application relates to a kind of carbon filament electric explosion preparation nanometer diamond powder method, belong to nanometer diamond preparation process technical field.The method is installed in the discharge tank of electric explosion system with discharge electrode by electrically conductive carbon filament, add specific medium to discharge tank and do good sealing, realize high-energy discharge by regulating and controlling the voltage of high-voltage capacitor group in electric explosion system, make the overheating coefficient of carbon filament 4~20, after discharge, repeat the electric explosion of multiple carbon filaments, recover the discharge product, remove metal and residual carbon phase, after washing and drying, obtain pure nanometer diamond powder.The method uses high-purity carbon filament as raw material, utilizes the high temperature and high pressure effect generated in the process of electric explosion to synthesize nanometer diamond, adjusts the energy input density by adjusting the overheating coefficient, and then controls the yield of diamond, the obtained product has high crystallinity and uniform particle size distribution.

The invention provides a method for preventing and controlling bee mites, which is characterized in that the mites are in a low-oxygen environment and lasts for a period of time, so that the mites cannot breed or the reproduction rate is reduced, or the reproduction of the mites is substantially failed, and therefore, the mite population gradually disappears, and the bees can survive. The environment is protected.

The application belongs to the field of new energy, and discloses a synthesis method of lithium tetrafluoroborate, which comprises the following steps: step 1: adding lithium halide into a non-aqueous organic solvent, and introducing boron trichloride to obtain a solution containing lithium haloborate; and step 2: introducing hydrogen fluoride into the solution obtained in step 1 to obtain a solution containing lithium tetrafluoroborate.
