The invention belongs to the technical field of aviation detection, and particularly relates to aviation cylinder clamping detection equipment, which comprises a frame body, and support plates are uniformly arranged on the inner wall of the frame body; the aviation cylinder clamping detection equipment further comprises an adjusting mechanism and a supporting mechanism, the adjusting mechanism is used for adjusting the arc-shaped thin-wall part so that the arc-shaped thin-wall part can make contact with the front face of the installed thin-wall part, the bottom of the adjusting mechanism is fixedly connected with the top of the frame body, and the bottom of the supporting mechanism is rotationally connected with the outer wall of the end, away from the supporting plate, of the frame body. By arranging the detection mechanism, the cushion block makes contact with the outer wall of the thin-wall part, the limiting assembly monitors the moving distance of the cushion block, when the thin-wall part reaches the critical deformation quantity, the position where the limiting assembly is pulled out at the moment can be recorded in time, the position is recorded, the cushion block can only reach the maximum position in the subsequent clamping process, and the clamping efficiency is improved. And the situation that the thin-wall part is deformed due to large extrusion force caused by unstable clamping force is avoided.

The invention discloses a pterostilbene bionic oral nano delivery system based on a lactobacillus helveticus exosome as well as a preparation method and application of the pterostilbene bionic oral nano delivery system. The preparation method comprises the following steps: extracting the lactobacillus helveticus exosome from a lactobacillus helveticus culture solution by adopting a method of combining continuous differential centrifugation and microporous membrane filtration; and mixing the lactobacillus helveticus exosome with pterostilbene, and carrying out ultrasonic treatment and incubation treatment, so as to prepare the lactobacillus helveticus exosome-pterostilbene bionic oral nano delivery system. According to the invention, the lactobacillus helveticus source exosome with the advantages of high yield and expansibility is successfully extracted for the first time, and the clinical limitations of high cost and low productivity of animal source and plant source exosomes as oral delivery carriers are improved; meanwhile, the prepared lactobacillus helveticus exosome-pterostilbene bionic oral nano-delivery system combines the natural characteristics of the exosome and the high biological safety of the probiotics, and can realize the balance of the oral delivery performance and the biological safety of the nano-carrier.

The alkali-free glass plate of the present invention is characterized in that the content of Li2O+Na2O+K2O in the glass composition is 0 to 0.5 mol%, the Young's modulus is 80 GPa or more, the strain point is 700°C or more, and the liquidus temperature is 1350°C or less.

The present invention provides a bracket applied to a roto-molding mold, belonging to the field of mechanical technology. It solves the problem that the existing roto-molding molds are prone to produce defective products due to the inability to evenly coat the internal plastic, melt and adhere to the entire surface of the mold cavity during the rotation or rotation process. The bracket applied to the roto-molding mold includes a first support assembly, the first support assembly includes a first support part; the first support part is rotatably connected to the first support mechanism; the first support frame and the second support frame are fixedly connected on both sides of the first support mechanism respectively; the rotating connection part drives the bracket to swing; the second support assembly is fixedly connected between the first support frame and the second support frame; the second support assembly is provided with a rolling abutment part. The present invention can reduce the pressure on the first support part when the roto-molding mold is in a swinging state through the second support assembly, which is beneficial to prolonging the life of the first support part.

This invention relates to an oligomerization method, preferably for the tetramerization of ethylene into 1-octene, the method comprising the step of injecting at least four compounds into an oligomerization reactor: - a chromium-based metal precursor; - a heteroatom ligand; - a supported methylaluminoxane on an inorganic support; - an additive in the form of an aluminum-based compound; wherein the chromium-based metal precursor and the heteroatom ligand are never in contact with the supported methylaluminoxane on the inorganic support in the absence of the additive in the form of an aluminum-based compound.
