This application provides a method, system, medium, and equipment for detecting thermal hazards in tunnels, relating to the field of tunnel safety detection. The method includes: acquiring geological feature data of the target tunnel; identifying a group of thermal hazard parameters with a correlation greater than a set threshold; setting a quantitative scoring range based on this; using the analytic hierarchy process (AHP) to assign weights and calculate hazard scores; then, combining relevant data to establish a dataset and training a lightweight gradient boosting model; finally, inputting data from an unexcavated tunnel section into the model to output the thermal hazard level. This application, by acquiring geological feature data, can accurately understand the environment, screen key parameters to eliminate redundancy, quantify parameters, and rationally allocate weights to ensure objective and accurate scores. It enables tunnel thermal hazard detection and early warning, providing guidance for prevention and control, reducing impact, and is of great significance to tunnel engineering.

The utility model belongs to the technical field of magnetic suspension motors, and particularly relates to a structure for improving the cooling quality of a magnetic suspension motor, which comprises a motor shell, a cooling air inlet is arranged on the motor shell, a motor stator is fixedly connected in the motor shell, a motor rotor is rotatably connected in the motor shell, and a metal pipe is fixedly sleeved on the motor rotor. According to the magnetic suspension high-speed motor rotor cooling air guiding structure, through reasonable design, the problem that the cooling effect is reduced due to the fact that a cooling air guiding structure is lacked nearby an existing magnetic suspension high-speed motor rotor is solved, the structure is simple and reliable, and the cooling effect is good.

The invention discloses a chemiluminescence immunoassay method and kit for detecting estrogen of pandas, and belongs to the technical field of biological detection. The specific process comprises the following steps: by taking goat anti-rabbit IgG as a coating antibody, enabling an estrogen standard substance or a sample to be detected and horse radish peroxidase labeled estrogen to compete with a limited amount of estrogen antibody; after incubation and washing, adding a chemiluminescent substrate, and quantitatively analyzing the estrogen in the urine or excrement of the panda according to a standard curve by detecting the intensity of a luminescent signal. Compared with an existing enzyme-linked immunosorbent assay method, the novel chemiluminescence immunoassay method provided by the invention has higher sensitivity (the lowest detection line can reach 9.75 pg / mL) and shorter detection time (only 40 minutes are needed in the whole process), and a rapid and accurate technical means is provided for oestrus identification and reproduction management of pandas.

The invention relates to the field of space region division and voice guidance, in particular to a gate dual-mode directional voice guidance method based on region division and related equipment. The method comprises the following steps: collecting a gate peripheral space image; according to the space image and a first preset division proportion, an in-channel interaction area and at least one out-channel pre-guiding area are divided, and the in-channel interaction area is used for performing face verification on passengers in the in-channel interaction area; a verification signal of the face and the certificate of the passenger is obtained from the in-channel interaction area, a first voice instruction is generated according to the verification signal, and a first set of loudspeakers is controlled according to the first voice instruction to deliver narrow-band sound beam voice of a first preset sound beam angle to the in-channel interaction area; and acquiring image information conforming to the special passenger characteristics from the out-of-channel pre-guiding area, generating a corresponding second voice instruction according to the image information, and controlling a second group of loudspeakers to deliver coverage sound beam voice at a second preset sound beam angle to the out-of-channel pre-guiding area according to the second voice instruction.

The utility model relates to notebook computer casing stamping technical field, and disclose a notebook computer casing stamping device, including frame and install in its surface lower mould still include: install in the surface of frame stamping mechanism, the surface fixed connection of frame has the fixing frame, the one side of fixing frame is provided with movable pipe, the one end intercommunication of movable pipe has the connecting pipe, the surface intercommunication of movable pipe has the nozzle of through quantity and position promotion cleaning effect, the utility model discloses the cooperation of movable pipe and nozzle can be through the effect of quantity and position conveniently to lower mould and stamping mechanism contact, under the cooperation of adjusting mechanism makes movable pipe can rotate, promotes the cleaning effect to foreign matter through changing air contact position, makes the device to foreign matter's cleaning more convenient, also to foreign matter cleaning in time to foreign matter orientation, solved the device when using, the problem that cleaning is more complicated, and the applicability is not good.
