Abstract: The present disclosure provides a prediction method and prediction apparatus for a lung function curve and a storage medium. The prediction method includes: obtaining a flow rate at M sampling points; and inputting the flow rate at the M sampling points into a prediction model; and the construction of the prediction model includes: constructing a Taylor series expansion of an N-variable Kth-order equation, and representing, through the Taylor series expansion, a relationship between a flow rate at a tth sampling point of a lung function curve and a flow rate at N sampling points preceding the tth sampling point. In the above technical solution, a finite number of valid data points can be used to predict true lung function curve data.

Abstract: The present invention discloses a dual meshing method and system for a transformer winding, comprising acquiring the working frequency of a target transformer, and carrying out a first meshing operation on the winding of the target transformer according to the working frequency with the combination of a first meshing strategy; carrying out a second meshing operation on the target transformer winding after the first meshing operation with the combination of a second meshing strategy; and acquiring the mesh size of the target transformer winding after the second meshing operation, and completing meshing on the target transformer according to the mesh size. By reasonably allocating the mesh sizes, the distribution of electromagnetic fields in the transformer winding can be accurately simulated, the consumption of calculation resources can be reduced on the promise of ensuing the accuracy, the simulation efficiency and the accuracy of the simulation result can be improved.

Abstract: The disclosure discloses an automatic drug delivery device for intelligent inhalation medication, including a drug inhaler, a drug inhalation action detection unit, a main control unit and an automatic pressing unit. The drug inhaler is a drug inhaler capable of drug delivery by pressing. The drug inhalation action detection unit is configured to detect whether the drug inhaler is subjected to a drug inhalation action and transmit a drug inhalation action signal to the main control unit. The main control unit is configured to correspondingly drive the automatic pressing unit to press a canister of the drug inhaler for drug delivery according to the received drug inhalation action signal.
