The invention discloses a salmonella H: i epitope specific monoclonal antibody and application thereof, the salmonella H: i epitope specific monoclonal antibody is secreted by hybridoma cells with the preservation number of CCTCC NO: C202645, and the antibody has the advantages of high titer and strong specificity. According to the blocking ELISA detection kit constructed by the antibody and the detection method of the blocking ELISA detection kit, the antibody containing H: i antigen epitope salmonella in infected animal serum can be specifically detected, the antibody does not react with antibodies containing no H: i antigen epitope salmonella and non-salmonella, the sensitivity, specificity and stability are good, and the detection method is simple and convenient. And a new method is provided for direct serological detection of H: i antigen epitope-containing salmonella infection of mouse typhimurium, kafenkii and the like.

The application relates to a detection mechanism, method, device and system of a fuel evaporation system, wherein the detection mechanism of the fuel evaporation system comprises a carbon tank, a valve part and a vane pump which are communicated with the carbon tank respectively; the valve part is provided with an intake manifold communication port and a fuel tank communication port; the vane pump comprises an impeller and a rotating speed sensor which is used for detecting the rotating speed of the impeller. The detection mechanism of the fuel evaporation system can improve the leakage detection efficiency of the fuel evaporation system, simplify the overall structure and improve the detection accuracy.

The utility model belongs to spline connection detection technical field relates to a device for detecting spline connection disc end surface tooth symmetry, include: work piece placing base, tensioning cover mandrel, tensioning cover, detection reference column, detection block, tensioning cover mandrel rotation connects work piece placing base, tensioning cover is covered and is established on the outer circumference of tensioning cover mandrel, and tensioning cover outer cover is equipped with spline connection disc, the boss of detection block is matched with spline connection disc end surface tooth groove, the top of detection reference column is equipped with detection reference groove, the utility model discloses through detection block and leads out the detection interface of spline connection disc end surface tooth, provides the contrast basis of detection device through detection reference column and blocks detection block, and the symmetry error of spline connection disc end surface tooth can be detected through the contrast of before and after detection value, therefore the utility model can effectively eliminate the clearance between spline mandrel and spline connection disc, and the accuracy of detection has been improved.
