The invention discloses an encrypted radiation imaging system based on a random thickness liquid mask, which includes an X-ray source, an object to be detected, a liquid metal mask, a thickness control array inside the mask, and an X-ray detector. The thickness control array randomly adjusts the thickness of the liquid mask, realizes random attenuation of the X-rays penetrating the mask, and then encrypts the sensitive information carried in the X-ray imaging, effectively protecting the sensitive information of the items to be inspected, and realizing Encryption measures of physical shielding are used for the energy and position information of the emitted particles, and the proposed security inspection technology encrypts the information carried by the emitted X-rays from the physical field, avoiding the risk of private information being leaked, and will not expose any information about the items to be inspected. For privacy information, the template comparison method is used to facilitate the confirmation of whether the items to be inspected contain contraband, and the security inspection is realized on the basis of protecting the sensitive information of the inspected items.

The invention discloses a selfheal dreg floatation seedling substrate and a preparation method thereof. The selfheal dreg floatation seedling substrate comprises 1 part of fermentative selfheal dreg, 0.5-1 part of earthworm excrement, 0-0.5 part of turf and 0.5-1 part of vermiculite. The preparation method is wide in the selection of raw materials, easy and convenient to operate and simple in process; the situation that the selection of the traditional substrate depends on non-renewable resources including perlite, vermiculite and the like is changed; the selected raw material is selfheal dreg abandoned by pharmaceutical factories, the seedling substrate is light in tactile sensation, and the porosity, volume weight and proportion of the substrate approximate to those of the turf, as a result, the pollution of the dreg to the environment can be solved, meanwhile, the waste dreg can be reused, and further the effects on environmental protection, energy economization and improvement of the utilization efficiency of humic acid are realized; the dreg is utilized as the main raw material of the seedling substrate, and the raw material is industrial waste residue, so that the cost is low, the preparation process is simple, and popularization and application are facilitated; the emergence rate of cabbages cultivated by utilizing the substrate can reach over 90 percent, the degree of uniformity of seedlings is high, the index of strong seedlings is also high, the growth is good and the cost is lowered.

The invention discloses a braking and retarding integrated supporting bridge for a trailer, which includes a supporting bridge part, a hydraulic retarder part, a speed-increasing mechanism part, a heat dissipation circulation system and a control module. The supporting bridge part includes a supporting axle housing, The hub and end cover, the hydraulic retarder part includes the left stator impeller, the right stator impeller and the rotor impeller, and the speed increasing mechanism part includes the sun gear, the planetary gear and the ring gear. The one-piece axle designs the position of the original braking mechanism as a hydraulic retarder, and the rotor impeller of the retarder is integrated with the sun gear of the speed-increasing mechanism, the right stator impeller and the ring gear, and the wheel hub and the planet carrier are integrated. The retarder provides power. The friction brake mechanism and brake drum are removed from the whole bridge, which greatly reduces the weight of the whole bridge as a whole. The two modes of retarder braking and retardation are controlled by air pressure to realize the adjustment and classification of torque and increase the sensitivity of vehicle operation. and driving safety.
