Abstract: The present invention provides an active capture device for African Swine fever aerosol and a detection method therefor. The device includes a hollow casing, and an aerosol capture mechanism and an internal circulating filtering mechanism which are disposed inside the casing; the casing includes a top plate and a bottom plate, and an annular side plate is disposed between edge positions of the top plate and the bottom plate; the aerosol capture mechanism includes a ventilation duct disposed at the front end of the annular side plate; one end of the ventilation duct is disposed inside the hollow casing and the other end of the ventilation duct penetrates through the annular side plate and is disposed outside the hollow casing; a fan is disposed inside the casing; the fan is communicated with the ventilation duct; and an adsorption pipe network is disposed inside the ventilation duct.

Abstract: The present application relates to an intention recognition method and apparatus, a readable medium, and an electronic device. The method includes: by means of a preset intention recognition quantification model, performing a quantification operation on a dot product of a query vector and a key vector which correspond to each character in a target text, so as to obtain a fixed-point type target vector of a first bit; according to the fixed-point type target vector, determining, by means of a target mapping relationship, a floating-point type attention weight of a second bit corresponding to each character; and according to the floating-point type attention weight, determining a target intention corresponding to the target text, the first bit being smaller than the second bit.
