Abstract: The present invention pertains to the field of steel smelting, specifically to a method for steel production in a blast furnace and a converter based on carbon cycling. The method comprises the following steps: 1. Smelting iron in a blast furnace to obtain molten iron; 2. Introducing the aforementioned molten iron into a converter and carrying out steel refining within the converter to obtain molten steel and untreated converter gas; 3. Subjecting the untreated converter gas to pressurisation, deoxygenation, dehydration, and decarbonisation treatments to obtain synthesis gas and treated converter gas; 4. Recycling the treated converter gas back into the blast furnace to regulate the ratio of reductive gases within the furnace atmosphere. Beneficial Effects: The method enables the cyclic utilisation of converter gas. By decarbonising the converter gas and recycling it back into the blast furnace, the content of reductive gases in the furnace atmosphere is enhanced.

Abstract: Provided are a rapid in-situ stratified collection device and method for sediment pollution in rivers and lakes. The device includes a main control system, a main collection system, a fixing frame, a bathymetric module, a working hull, and a crane. The bathymetric module is installed below the working hull, the main control system and the crane are both installed on the working hull, the main collection system is fixed in the fixing frame and connected to the crane. The bathymetric module is used to detect and determine a water depth, and thicknesses of sediment. The main control system is used to control a collection process of the main collection system, read the water depth and a thickness of the sediment in real time, and determine whether the main collection system is completely inserted into the sediment. The main collection system is used for stratified collection of sediment pore solution.

Abstract: The application discloses a coating material for fabricating rare earth magnets and a method using the coating material to prepare neodymium-iron-boron (NdFeB) magnets having high coercive force. The coating material includes alloy powder A and low-melting-point metal powder B. The alloy powder A is heavy rare earth element R powder, or rare earth-metal alloy (RM) powder, or rare earth-metal-hydrogen alloy (RMH) powder. The heavy rare earth elements are Dy and/or Tb, metal is Fe or Co, or an alloy of Fe and Co, and H is hydrogen element. The low-melting-point metal powder B is one or two of Zn, Al, and Ga. The preparation method includes the following steps: the coating material is mixed into a slurry, and the slurry is coated on the surface of NdFeB magnet, and then apply a two-stage diffusion heat treatment to the magnet, followed by an annealing process to obtain a high-coercivity NdFeB magnet.

Abstract: A position selecting method of a U-turn median opening at a signalized intersection under the influence of traffic flow compositions. In the process of determining the traffic capacity of a left-turn lane, different influences of various vehicle arrival modes on the utilization rate of the left-turn green light and the utilization rate of the U-turn green light are analyzed. A method for the traffic capacity of the left-turn lane with the U-turn median opening at a signalized intersection in combination with traffic management demands and traffic flow space-time characteristics is provided, so that the traffic capacity of the left-turn lane under the influence of actual traffic flow compositions is calculated more accurately.

Abstract: A system and method for frequency hopping precalibrates a subset of a plurality of channels, storing the channels' associated curves in a computer readable medium. Before hopping to a new channel, decision making circuitry can access the precalibrated curves. If the destination channel has an associated curve, then the system can use the values from that curve when hopping to a new channel. If the destination channel does not have an associated precalibrated curve, then the system can identify a closely situated channel with a precalibrated curve and use an offset value to settle at the destination channel. According to another aspect of the present invention, the offsets can be updated. According to a further aspect of the invention, the updated can be done dynamically.

Abstract: A dithering system yielding two-dimensional dither functioning is implemented without line memories. For each primary input color, a feedback loop outputs an color input signal plus error that can be preset to different values. The desired result is that vertical artifacts on a display formed from the output signals are relocated to different locations on consecutive display lines. If signal magnitude from the feedback loop output exceeds the magnitude of the video system creating the display, signal magnitude is preset to a value representing error at the start of the display line.
