The invention discloses a preparation method of a high-entropy phosphide nanotube, which successfully prepares a nanotube phosphide with a high-entropy structure by adopting a hydrogen bond organic framework (HOF)-metal organic framework (MOF) template conversion method. In the preparation process of the material, a core-shell structure (HOF (MOF)) is firstly formed, the core gradually disappears through a diffusion mechanism, and finally, the material is converted into a hollow nanotube structure which is uniform and controllable in size. According to the hollow structure, the specific surface area is remarkably increased, more active sites are provided, the transmission path of reactant molecules is optimized, and the electro-catalytic performance is greatly improved. Besides, the overall tubular morphology of the material is uniform, the size is controllable, and compared with a traditional granular material, the specific surface area is remarkably increased, so that more reaction sites are exposed in the external environment, and the catalytic efficiency and the reaction rate of the material in an electro-catalytic reaction are greatly improved.

The invention provides a standard decoction of pawpaw decoction pieces, further provides a characteristic spectrum construction method of the standard decoction of pawpaw decoction pieces and an identification method of the standard decoction of pawpaw decoction pieces, and further provides a method for identifying production places of pawpaw medicinal materials in the standard decoction. According to the construction method of the specific chromatogram, the special requirements of a chromatographic column are reduced, the analysis time is shortened, the detection efficiency is improved, the preparation of a test solution and the selection of characteristic peaks are optimized, the precision is high, the stability is good, the repeatability is good, and a new choice is provided for the quality detection of papaya medicinal materials, decoction pieces, standard decoction and formula granules.

This utility model discloses a self-locking anti-loosening nut, comprising a nut body, a stabilizing pad fixedly connected to the bottom of the nut body, and a self-locking mechanism provided on the upper part of the nut body. The self-locking mechanism includes a positioning plate fixedly connected to the top of the nut body, a chuck inserted inside the positioning plate, and a self-locking seat fixedly provided on the inner ring surface of the chuck. This self-locking anti-loosening nut requires no special processing, such as drilling or grooving, and can be directly used with standard threaded bolts, offering high compatibility and reducing special requirements for matching parts. It does not reduce the strength of the nut body and will not deform under tightening force. The modular design ensures that the lifespan of the nut body is not affected by the wear and tear of the self-locking mechanism, significantly improving the product's durability and economy. The replacement process is simple, requiring no professional tools or complex procedures, reducing maintenance difficulty and time costs, and is especially suitable for rapid on-site repairs.

The utility model discloses a special pouring mold for an epoxy resin pouring bus, and relates to the technical field of bus duct processing. Comprising a bus duct body, a mold body is detachably installed outside the bus duct body, the mold body comprises a first L-shaped mold closing plate and a second L-shaped mold closing plate, the two ends of the first L-shaped mold closing plate extend to be provided with first mounting plates, the two ends of the second L-shaped mold closing plate extend to be provided with second mounting plates, and a sprue gate is formed in the top of the second L-shaped mold closing plate in a penetrating mode; a pouring sealing plate is mounted at the upper end of the pouring opening; the pouring sealing plate and the second L-shaped mold closing plate are fixed through the butterfly-shaped short-rod bolt, after epoxy resin in the mold body is solidified, the first L-shaped mold closing plate and the second L-shaped mold closing plate can be removed by taking down the fastening bolt, and therefore pouring is completed, operation is more convenient, and the effects of being safe, reliable and capable of meeting design requirements are achieved. And the special requirements on operators are effectively reduced, so that the construction task can be efficiently completed.
