Abstract: The present disclosure provides an image registration method and system for navigation in femoral neck fracture surgery, an electronic device, and a computer-readable storage medium. The method includes: obtaining femoral image data by a computed tomography (CT) imaging device before surgery and obtaining a surgical path planned by a doctor to generate a three-dimensional femoral image with the surgical path; obtaining, during the surgery, X-ray images photographed by an X-ray machine at different angles, and extracting feature points on each of the X-ray images; setting digitally reconstructured radiograph (DRR) virtual scene projection parameters based on a structure of the X-ray machine, projecting the three-dimensional femoral image with the surgical path to generate a plurality of DRR images, and extracting feature points on each of the DRR images; and automatically registering the DRR image and the X-ray image, and outputting a surgical path after registration.

Abstract: A method for washing and purification with a low-temperature methanol at least includes the following steps: condensing a raw shift gas and conducting a gas-liquid separation to obtain CO2-containing liquid and a separated raw material gas; and vaporizing the CO2-containing liquid and reducing a pressure by an expansion to obtain a CO2-containing gas; and washing the separated raw material gas with a methanol to obtain a purified gas. The present application combines CO2 condensation and an expander, so that the load of cooling capacity of the system for washing with a low-temperature methanol is reduced by 60%. At the same time, the external work done by the expander reduces the energy consumption of the system. After the CO2 in the purifying gas of desulfurization in the section A of the scrubber is condensed, the amount of CO2 entering the section B is reduced.

Abstract: A method for HARQ reordering in Enhanced Uplink Dedicated Channel of WCDMA system includes following steps: locating the soft combination buffer in the Node B and the reordering buffer in the SRNC; locating the HARQ entity in the Node B; locating the reordering queue distribution entity, the reordering entity and the disassembly entity in the SRNC. This invention adopts the separation technology of the soft combination buffer and the reordering buffer, the separation model can not only ensure the diversity gain, but also reduce the receiving delay and save the buffer space. Three mechanisms (timer mechanism, window mechanism and SBI mechanism) are proposed to prevent the blocking of the reordering buffer, which degrades the blocking to the least level, improves the receiving efficiency and the system performance. Aiming at the SBI mechanism, the invention proposes the new DCH data frame structure on the Iub interface and the Iur interface.
