The invention discloses a permeation device and method. The permeation device comprises a heating chamber, a rotary tray, rotary brackets, material boxes, a lifting mechanism and a transmission device, wherein the heating chamber is provided with an annular groove, and the rotary tray is arranged below the opening end of the lower end of the heating chamber; the rotary brackets are mounted on the rotary tray; the material boxes are arranged on the rotary brackets; the rotary brackets and the material boxes can ascend and descend under the action of the lifting mechanism; the rotary brackets can rotate in the annular groove under the action of the transmission device and revolve around the center axis of the rotary tray. The permeation method comprises the steps of material charging, vacuum pumping, high-temperature permeation, cooling, material taking and other steps. By means of the permeation device and method, the condition equality of the magnet positions and the condition equality of the heating environment are both achieved, so that the uniformity of the temperature condition required by sintered magnets in the high-temperature permeation and air cooling process is satisfied, and the consistency of properties of products is guaranteed.

The invention discloses a device and a method for testing a system-on-chip chip with a plurality of isomorphic IP cores. The device comprises a controller and a condition comparator, wherein the controller is provided with a plurality of control signal interfaces connected to each corresponding isomorphic IP core and is used for inputting a test control signal to each isomorphic IP core, controlling the test on one or more isomorphic IP cores, broadcasting the same test excitation data to the IP cores and simultaneously controlling the output of a test response of a certain IP core; the test response serves as a reference test response and is compared with the test responses of other IP cores; and the condition comparator is used for comparing the test response of a corresponding IP core with the reference test response and processing the comparison result to produce a one-bit error identification signal for identifying whether the comparison is accordant.

The present invention relates to a laying device and laying method of thermal insulation material on the outer wall, comprising a shell, a recovery frame, a packing device, a mortar frame, a carding block, a scraping plate and a sliding wheel group, the inner lower end of the shell is installed with Filling device, a recovery frame is installed inside the shell, and the recovery frame is located directly below the packing device, a mortar frame is installed on the upper end of the shell, a carding block is evenly installed on the front end of the shell, and a The scraper plate is equipped with a sliding wheel set on the lower side of the front end of the housing. The invention can solve the problem that in the process of plastering the wall, personnel need to carry a material cylinder with mortar with them and wipe it on the wall. Since the personnel are working at high altitudes, their own safety may be threatened due to the relatively large range of motion of the personnel working at high altitudes. When working, the personnel themselves are prone to shaking, which makes it difficult to plaster the wall, and the mortar layer on the wall will have uneven thickness and loose mortar layer.

The invention relates to an air-uniformizing and thermoforming baking oven which comprises an oven body, a heater, a conveying chain plate, a suction hood, a reflux pipeline and a draught fan, wherein the bottom of the oven body is provided with an air uniformizing device which is composed of an air inlet pipe and an air uniformizing chamber; one end of the air inlet pipe is connected with the draught fan, and the other end of the air inlet pipe is connected with the air uniformizing chamber; the air uniformizing chamber comprises an end plate, two side plates and a bottom plate; the end plate is provided with an air inlet; the air inlet pipe is connected with the air inlet; multiple inclined air deflectors are arranged in the air uniformizing chamber; flow channels are respectively formed between the multiple air deflectors and the bottom plate and are connected with the air inlet; one ends of the multiple air deflectors are respectively connected with the end plate, and the other ends of the air deflectors are parallel to one another and are respectively provided with multiple air outlets. The air-uniformizing and thermoforming baking oven can be used for not only ensuring that air absorbs the same heat in the heater and thus the service life of the heater is prolonged, but also ensuring that fibers absorb the same quantity of heat and thus the fiber thermoforming degree is stabilized, and further ensuring the product quality consistency.

The invention relates to a complex RCS data interpolation method based on compressed sensing, and belongs to the technical field of comprehensive testing. A specific implementation of the method includes: constructing a complex domain reconstruction model according to the RCS measurement data; solving the complex domain reconstruction model to obtain the sparse distribution of the RCS data; reconstructing target frequency domain data based on the sparse distribution , realize complex RCS data interpolation. Compared with the traditional method of simply diagonalizing complex matrices, the invention does not reduce or increase the original constraint range, has fast processing speed and high precision, and can effectively shorten measurement time to improve RCS measurement efficiency.
