    摘要: The present disclosure relates to a hazardous chemical collection apparatus and a gate system. The hazardous chemical collection apparatus comprises a vibration portion (2) and a collection portion (3). The vibration portion (2) applies a vibration to an access credential (11) such that hazardous chemical attached onto the surface of the access credential (11) falls off. The collection portion (3) is positioned below the access credential (11) to collect the hazardous chemical falling off from the access credential (11). The gate system comprises the hazardous chemical collection apparatus. The hazardous chemical collection apparatus provided in the present application can automatically complete a hazardous chemical collection, is not easily perceived by a passing person, saves cost of sampling test papers, has considerable economic benefit, reduces the workload of security screeners, and reduces human resources management cost.

    摘要: Additive manufacturing apparatus utilizing combined electron beam selective melting and electron beam butting. The additive manufacturing apparatus comprises an electron beam emitting, focusing, and scanning device (6) capable of emitting electron beams (67, 68) for use in a heating mode, a selective melting mode, or an electron beam cutting mode. In the heating mode, the electron beam emitting, focusing, and scanning device (6) emits an electron beam to scan and preheat a powder bed (7). In the selective melting mode, the electron beam emitting, focusing, and scanning device (6) emits the electron beam (67) to scan and melt powder (71) in a cross-sectional outline to form a required component cross-sectional layer. In the electron beam cutting mode, the electron beam emitting, focusing, and scanning device (6) emits the electron beam (68) to perform one or more cutting scans on inner and outer outlines (74, 75) of a component cross-section to obtain accurate and smooth inner and outer outlines of the component cross-section. The electron beam emitting, focusing, and scanning device (6) is further configured to repeat the heating, selective melting, or electron beam cutting processes to obtain a required three-dimensional physical component.

    摘要: Embodiments of this application provide a data transmission method and apparatus. The method includes: determining a first sending rate based on a network performance objective of first data and a network status of a first transmission control protocol (transmission control protocol, TCP) connection of a transport layer protocol, where the first TCP connection is used to send the first data; and sending the first data based on the first sending rate. The network performance objective is set, so that an output of a decision not only depends on the network status, but also depends on the network performance objective. In this way, network congestion control is more flexible, and TCP-based data transmission efficiency is improved.

    摘要: An additive manufacturing device comprises: a vacuum forming chamber (1), a worktable device, a powder supply device, at least one electron beam (EB) emission focusing and scanning device (6), at least one laser beam emission focusing and scanning device (7), and a controller. A forming region of the worktable device is at least provided within the vacuum forming chamber (1). The powder supply device is configured to supply powders to the forming region. Scanning ranges of the EB emission focusing and scanning device (6) and the laser beam emission focusing and scanning device (7) are configured to cover at least a part of the forming region. The controller is configured to control the EB emission focusing and scanning device (6) and the laser beam emission focusing and scanning device (7) so as to perform a powder scanning and forming integrated treatment on the forming region. The additive manufacturing device can apply additive manufacturing to create three-dimensional parts having a good-performance, high-efficiency, and high-precision, and highly adaptive to different materials.
