The passive self-adaption magnetorheological deceleration strip can adjust the rigidity of the deceleration strip at real time and automatically according to the vehicle speed of the vehicle and have no obstruction action to the vehicle at low speed, the comfort is increased, the vehicle and deceleration strip are protected for reducing the speed for the vehicle at high speed for having the reasonable reminding and punitive action.

The invention relates to an air purifier, which comprises a purifying main body, one side of the purifying main body is provided with an air inlet, a filter and a fan are arranged sequentially along an air flow path in the purifying main body, and the entire purifying main body is covered by the filter; the purifying main body is provided with an air passage at a position corresponding to the fan; the air passage is communicated with an air outlet formed in one side of the purifying main body; a flow guide plate for air flow is arranged at one side of the fan, the flow guide plate is divided by ribs, and the ribs are in contact with the filter. The air purifier is small in size and lightweight, and therefore is convenient to carry, the air supply and filtering power is high, active air supply is adopted, breathing resistance is low, and the air purifier is comfortable.

The invention discloses an advertising device automatic control method, which belongs to the technical field of advertising display. The method adopts an advertising device with the control method comprising the following steps of firstly controlling a second motor to rotate or stop anticlockwise through a microprocessor according to the rotary period values of two motors, and rotary time values and stop time values of the motors; then controlling a third motor to rotate or stop clockwise; meanwhile, sensing the humidity of weather and transmitting to the microprocessor through a humidity sensor, processing a humidity signal value through the microprocessor, transmitting the humidity signal value and preset motor rotary time values to a first drive unit at the same time to control a first motor to forward or reverse; meanwhile, sensing the brightness of the weather through a brightness sensor and transmitting to the microprocessor; processing a brightness signal value through the microprocessor, and controlling the on or the off of an LED (Light-emitting Diode) light. The advertising device automatic control method provided by the invention can solve the problems that the existing high-rise advertising board has less information content, and an advertising box body is immersed easily so as to enable the advertising content to be indistinct and damaged since a rainshed cannot be set.

The invention belongs to the field of chemical looping combustion and particularly designs an application method of a nickel (Ni)-loaded mesoporous silicon dioxide hollow sphere iron-based oxygen carrier. According to the invention, a mesoporous silicon dioxide hollow sphere is taken as a carrier, NiO servers as an active catalytic ingredient and is loaded on the outside surface of the hollow sphere and the surfaces of mesoporous passages, Fe2O3 serves as an active oxygen-carrying ingredient and is filled into the inside cavity of the hollow sphere, and then, an iron-based oxygen carrier based on the Ni-loaded mesoporous silicon dioxide hollow sphere is obtained; in the Ni-loaded mesoporous silicon dioxide hollow sphere iron-based oxygen carrier, the mass percent of the NiO and the mass percent of the Fe2O3 are respectively 0.1-2% and 58-90%; and the direct chemical looping combustion of solid fuels, such as coal, biomass and the like, can be achieved by using the Ni-loaded mesoporous silicon dioxide hollow sphere iron-based oxygen carrier. The Ni-loaded mesoporous silicon dioxide hollow sphere iron-based oxygen carrier has the advantages of excellent reaction activity and stability and long service life during the process of the direct chemical looping combustion of the solid fuels, such as the coal, the biomass and the like.

The invention discloses a combined steaming oven (10') with a cooking chamber. The cooking chamber is outwards defined through a bottom (14), walls (15, 16, 18 and 20) and a door (22). The cooking chamber (12) is provided with a steam generator and a first heating device (28) which is arranged on at least one of the walls (15, 16, 18 and 20). The bottom (14) is provided with a second heating device (30). Both the two heating device (28 and 30) are arranged outside the cooking chamber (12). The bottom (14) is constructed as a cooking area (32) provided with the second heating device (30). The walls (15, 16, 18 and 20) are constructed as a heating area (31) provided with the first heating device (28) respectively. The cooking area (32) can be pulled out from the cooking chamber (12) in a drawer mode. Therefore, when the cooking area (32) is positioned inside or outside the cooking chamber (12), dishes can be prepared on the cooking area (32).
