The invention discloses an oral cavity dilator. The two ends of the outer side of an upper opening plate and the two ends of the outer side of a lower opening plate are each provided with two tooth pads; one ends of the upper opening plate and the lower opening plate are connected through two movable frames A, the other ends of the upper opening plate and the lower opening plate are connected through two movable frames B and a V-shaped connector, one ends of the two movable frames A are fixedly connected with one ends of the upper opening plate and the lower opening plate respectively, the other ends of the two movable frames A are connected through a connecting ring, the two movable frames B are arranged in a crossed mode, one ends of the two movable frames B are fixedly connected with one ends of the upper opening plate and the lower opening plate, and the other ends of the two movable frames B are connected with the inner side faces of the upper opening plate and the lower opening plate in a sliding mode; a traction steel wire is connected to the crossing point of the two movable frames B, a soft connection rod is installed at the front end of the V-shaped connector, the traction steel wire penetrates through the center of the V-shaped connector, and the soft connection rod is connected with a traction steel wire storage box. The oral cavity dilator can remotely control opening and closing of teeth, so that the oral cavity is in a movable open state; besides, the oral cavity dilator has a tongue pressing function and is convenient to use.

The invention discloses a color grading monitor, which has a LUT mapping function and is used for performing LUT mapping on an input signal image. The color grading monitor has a LUT storage unit. The color matching monitor further comprises: a receiving module for receiving LUT data; a parsing module for analyzing whether the LUT data meets a predetermined condition, and if so, updating the received LUT data to the LUT storage unit and perform a new LUT mapping; if the predetermined conditions are not met, discard the LUT data; and a display module, configured to display the input signal image after the new LUT mapping according to the analysis result of the analysis module. The present invention also provides another color grading monitor and a color grading system and method having the same.

The invention discloses an oil seepage detection device for parts of an automobile bridge box, which relates to the technical field of automobile parts detection, and comprises a base, and a support seat and a transparent detection box are respectively fixedly installed on both sides of the top outer wall of the base. The top of the support seat is provided with a circulating mixing assembly; the present invention uses a warm water supply pipe to flow warm water into the transparent detection box. When there is a penetration point, the pigment will ooze out from the test part and quickly dissolve in the penetration point. In the water, it can cause rapid local color changes in the water, thereby facilitating the detection of penetration points; at the same time, the continuous water supply of the warm water supply pipe can cooperate with the pumping effect of the liquid outlet pipe, so that the warm water can achieve stable and continuous lateral flow under the action of the diversion horizontal plate , when infiltration occurs, the pigment continues to ooze out at the infiltration point. Under the action of the lateral flow of water, a ribbon-shaped water flow starting from the infiltration point can appear, so that the inspector can observe the infiltration position conveniently.

The invention discloses a scanning electron microscope sample processing method for head sensory appendages of white ants. The method comprises the steps of putting white ants into a specially-made wind washing device, carrying out wind washing, feeding the white ants into a specially-made auxiliary vacuumizing device, carrying out vacuumizing operation to sink the white ants, carrying out front fixing and dissection, sequentially carrying out front rinsing under the view of a stereoscope and in an ultrasonic cleaner, carrying out rear fixing, rear rinsing and step-by-step gradient dehydration, putting the white ants into a specially-made filter paper cylinder, sealing the filter paper cylinder, putting the filter paper cylinder into a critical point drying frame, carrying out critical point drying, bonding samples close to a platform under the stereoscope, further dissecting target tissues of partial samples, carrying out secondary sample bonding, connecting the samples which are not subjected to secondary sample bonding with sample bonding adhesive tapes in a non-target observation region by virtue of a conductive silver adhesive, and carrying out all-direction gold sputtering after the conductive silver adhesive is dried. According to the scanning electron microscope sample processing method, multi-aspect technical problems in the background art that the surfaces of the samples are polluted, the samples are difficult to sink in fixation liquid and shrink to deform, different tissue parts of the samples are mutually shaded, and the samples are charged and discharged when being observed in an electron microscope are effectively solved, the cost for solving the problems is low, and the method has relatively high application value.

The invention discloses a civil engineering structure explosion damage experiment platform, which comprises a base plate, a plurality of pillars and a plurality of cross bars welded on the corresponding pillars, the middle part of the base plate is provided with a locking device for fixing a test piece, the Both sides of the locking device are symmetrically provided with a first test device and a second test device for testing explosion parameters, and a plurality of cross bars are jointly provided with fixing devices for fixing explosives. There are two protective plates at both ends of the base plate, each of which is slidably provided with a plurality of screws. The invention has a novel structure, and can detect explosion pressure parameters in various directions around the test piece. When the shock wave generated by the explosion propagates around, the first test board and the second test board can not only rely on their own strength to resist the impact force, but also The kinetic energy of the shock wave can be converted into the kinetic energy and internal energy of multiple devices to avoid damage to the experimental platform.
