The invention belongs to the technical field of immunohistochemical detection, and discloses a modified composite sealing buffer solution as well as a preparation method and detection application thereof. The modified composite blocking buffer solution comprises a basic buffer system, a composite blocking agent, a nonionic detergent, an endogenous interferent blocking agent and an antibody stabilizer, wherein the basic buffer system provides a stable pH environment and ionic strength; the composite sealing agent firstly occupies a shielding site, and the background is lowered; the nonionic detergent destroys hydrophobic interaction, effectively elute and loosen adsorbed molecules, and promote dissolution of components with relatively strong hydrophobicity; the endogenous interferent blocker can be combined with a receptor firstly, so that non-specific combination of an antibody and the receptor is blocked, and the problem of specific background is solved; the antibody stabilizer can protect the activity of the detection reagent and maintain the stability, and the obtained modified composite sealing buffer solution and the kit thereof have the advantages of multiple cooperative sealing mechanisms, prospective blocking of endogenous interference, improvement of the stability, compatibility and high efficiency of the antibody and the like.

This application relates to the field of aquaculture monitoring technology, and provides a method and corresponding product for estimating fish population size based on forward-looking sonar data. The method includes: acquiring sonar monitoring data obtained from a forward-looking sonar device monitoring a target water area, and constructing an effective monitoring area in the sonar monitoring data according to the field-of-view parameters of the forward-looking sonar device; preprocessing the sonar monitoring data located within the effective monitoring area to enhance the distinguishability of fish targets; identifying fish targets located within the effective monitoring area based on the preprocessed sonar monitoring data, and generating an initial population estimate based on the number of identified fish targets; acquiring aggregation characteristics reflecting the aggregation state of fish within the effective monitoring area; and correcting the initial population estimate based on the aggregation characteristics of fish within the effective monitoring area to obtain a corrected fish population estimate.

This invention discloses a cross-platform dynamic evaluation method and system for public opinion based on real-time semantic perception, belonging to the field of online public opinion data processing. The method includes the following steps: collecting multi-platform, multi-modal, heterogeneous data; standardizing the data; semantically aggregating the standardized cross-platform multi-modal data corresponding to each propagation event based on an event semantic center vector model; iteratively updating the event semantic center vector through online exponential sliding updates to address the dynamic evolution of propagation events, continuously supplementing the event semantic center vector with newly added standardized data related to the propagation event in real time; quantitatively evaluating the comprehensive performance of each propagation event on different platforms based on a platform performance index model, and constructing a cross-platform content ranking based on the comprehensive performance using a multi-attribute normalized decision function; and intuitively presenting the cross-platform online public opinion analysis results using a three-level responsive visualization view.

The application provides a reversible grinding automatic line suitable for H-shaped steel products, comprising a processing chamber and a conveying line passing through the processing chamber; a robot and a material turning mechanism are arranged in the processing chamber, the robot and the material turning mechanism are respectively located on two sides of the conveying line, and an end of the robot is provided with a polishing part; a first linear module is arranged at the bottom of the robot; a second linear module is arranged at the bottom of the material turning mechanism; the material turning mechanism comprises a circular seat and a power part for driving the circular seat to rotate, one side of the circular seat is provided with a side groove; a scraper is arranged in the side groove, and the scraper is connected with a driving mechanism, and the driving mechanism is used for driving the scraper to move in translation along the side groove.

The invention relates to an air cooling heat dissipation structure of an elevator energy recovery device. The air cooling heat dissipation structure comprises airflow holes, a shell, deflection baffles and a cabinet door. The shell is composed of a cuboid-shaped shell body and a top cover plate, and the top cover plate is welded to the top of the cuboid-shaped shell body. Cabinet doors are hinged to two sides of the shell; airflow holes are formed in the top bottom of the shell and the cabinet doors; the deflection baffles are arranged on the inner wall of the shell and arranged on the same vertical plane in a vertically-spaced and crossed mode. The system has the beneficial effects that airflow generated when the elevator runs in the hoistway is adopted as a cooling medium of the energy storage battery, the heat exchange effect is high, temperature distribution is uniform, and cost is zero; heat generated in charging and discharging of the energy storage battery is quickly brought out of the equipment by airflow, so that the problem of heat accumulation of the equipment is effectively solved with zero cost, the energy-saving device is more energy-saving, and meanwhile, the structure is simple in process; the deflection baffles are arranged on the inner wall of the shell and are arranged on the same vertical plane in a vertically-spaced and crossed mode, the flowing time and distance of airflow in the shell are prolonged, and heat exchange is more sufficient.
