Abstract: A novel dry powder inhaler. By providing a plurality of capsule chambers (1a, 1b, 1c, 1d) arranged in parallel in a capsule dry powder inhalation device, a medicine dispenser containing active components of a composite product or their mixture separately is provided. The dry powder inhaler has a simple structure and is convenient to operate. In addition, the parameters of air inlet channels and an air outlet channel can be adjusted by means of each capsule chamber (1a, 1b, 1c, 1d) according to the properties of powder of a medicine or a combination, so as to provide an appropriate particle distribution for each active component.

Abstract: The present disclosure provides a method for automatic modeling of an architecture based on an architectural drawing, comprising steps of: reading parameter information of the architectural drawing, identifying a category to which any architectural object belongs by acquiring line segments constituting the architectural object and coordinate data of endpoints of the line segments; generating a binary file or a preset number of binary files based on the coordinate data and elevation data of the endpoints of all the line segments of architectural objects belonging to the same category for all storeys of the architectural drawing; optimizing the binary file or the binary files corresponding to the architectural objects belonging to the same category for all the storeys of the architectural drawing; and generating a three-dimensional model of the architecture. The modeling precision and modeling efficiency of the architecture can be improved by adopting the technical solution of the present disclosure.
