6results about How to "Recognition is intuitive" patented technology

The application discloses an immune detection method for accurately quantifying structural analogues and application thereof. The immune detection method can realize accurate, intuitive and rapid identification and quantification of target analytes by combining wide-spectrum antibodies and specific antibodies to recognize structural analogues and by establishing a three-dimensional curved surface model through a multilayer perception machine model, and can solve the problem of false positive results in the detection process due to the high structural similarity between a certain target analyte and another substance in the immune analysis method, especially for analytes with indistinctive characteristic structures and cross substances, which are often difficult to prepare high-specificity antibodies. The immune detection method is simple to operate, does not require experimental personnel to take multiple verification measures, and greatly reduces the cost burden of detection. The application has great significance and broad application prospect for improving the accuracy of rapid detection of residual substances in food.

This invention provides a pressure testing device for gas storage tanks, belonging to the field of pressure vessel technology. It solves the technical problems of existing high-pressure gas pipe sealing tests, such as the inability to detect leaks during pressurization and the risk of explosion during testing. This pressure testing device for gas storage tanks includes a water tank, a booster pump, a pressure vessel, a main inlet water pipe, a main return water pipe, an inlet connector, and multiple inlet and return water branch pipes. The inlet connector has an inlet valve near the end of the main inlet water pipe and a pressure relief port in the middle, with a pressure relief valve at the pressure relief port. Each return water branch pipe has a return water valve at its connection to the main return water pipe. A water pump is connected to the main return water pipe to pump water from the pipes back to the water tank. This invention uses water as the detection medium, which is less prone to explosion; and it allows for direct visual observation of water leakage on the outer wall of the gas storage tank during pressurization, thus enabling rapid and intuitive identification of leaks at an early stage.
