The invention relates to a method for recovering rare earth from waste aluminate green rare-earth phosphor. The method sequentially comprises the following steps of carrying out calcination pretreatment on waste aluminate green rare-earth phosphor, leaching out the calcinated product by using hydrochloric acid and hydrogen peroxide and precipitating rare earth with oxalic acid. The method has the advantages of simple process steps, high recovery of rare earth (the leaching rate of rare earth is above 93%) and low cost, and the problem of difficulty in recovering rare earth from waste aluminate green rare-earth phosphor is solved.

The invention discloses an access control method, user equipment and system of the internet of things. The user equipment includes an instruction obtaining module, an access control module and a result receiving module. The system includes a central server, a proxy server, a gateway, an Internet of Things device and a user device. Through the cooperation of identity-based encryption technology and proxy server based on message queue transmission protocol, at the same time, by verifying the digital certificate of the first user in advance when generating the first capability token chain, after the verification is passed, the digital certificate is placed in the In and signed in said first chain of capability tokens, the method, user device, and system not only avoid the generation of a large number of keys and the attendant key management burden, but also enable the verification of digital certificates for visitors The procedure is carried out together with the signature verification procedure of the first capability token chain, which improves the response speed of access control while ensuring the legitimacy of access control.

A printer base plate leveling device and leveling method, comprising a mounting base, a printer base plate disposed on the mounting base, the printer base plate is fixed to the mounting base by adjusting screws, and a return spring, the return spring is set on the adjustment screw; the installation base is provided with two uprights, the upright is provided with a cross bar, the cross bar can slide along the upright post, the cross bar is provided with a slide rail, the slide rail can slide along the cross bar, The slide rail is provided with a detection head, and the detection head can slide along the slide rail; the detection head includes a shell, a detection bar, and an induction probe.

The invention discloses a method for estimating a non-Newtonian index of a resin material by utilizing an injection molding machine. The method comprises the following steps: arranging a pressure sensor in the injection molding machine to measure integral total pressure drop data in the injection molding machine and calculating theoretical pressure drop of each position according to the dimension of each part on the injection molding machine and an adaptor; and carrying out linear fitting to obtain the non-Newtonian index of the material. The method is convenient in operation and simple in step flow; and results obtained by virtue of the linear fitting are high in accuracy. The method is used for the field of injection molding.

The present invention relates to the method for preparing composite photocatalyst CdS / ZIF-8 by one-pot method, comprising the following steps: S1: dissolving alcohol-soluble zinc salt and cadmium salt in methanol, stirring until clear and transparent to obtain the first solution; Methylimidazole is dissolved in methanol, stirred until clear and transparent to obtain a second solution; S2: quickly pour the second solution into the first solution, stir to obtain a mixed solution, and leave the mixed solution to react for a period of time; S3: In this mixed solution, add alcohol-soluble sulfide-, react under stirring; S4: After the reaction finishes, separate precipitation, wash, dry, obtain composite photocatalyst CdS / ZIF-8. The method of the invention has few steps, simple process and is suitable for industrial application. Through experimental tests, it was found that compared with pure CdS, the prepared CdS / ZIF-8 composite catalyst showed better hydrogen production performance and cycle stability, which showed that it had broad industrial application prospects and provided a basis for catalyst design. important reference.

The invention provides a method for realizing interconnection among various heterogeneous home network standards, including the following steps: receiving a request to abstract service by a user and the parameters thereof; inquiring about the configuration files registered by the service providers in aspect of abstract service, and acquiring the configuration files satisfying the requirements of the user; finding the service instances corresponding to the abstract service and generating a candidate execution plan list according to the acquired configuration files and the using state of the service resource nodes; and selecting one execution plan to complete the corresponding specific service; wherein the configuration files include the combination condition of the specific services and the implementation logics thereof. The method can provide a simple and unified abstract service-oriented operation interface for the user, thereby simplifying the process flow that the user has to deal with. When the home network standard supported by the user is different with the home network standard of the bottom-layer service, the required service can be achieved without re-collocating the execution flow of the corresponding standard.
