The present application relates to a kind of polymerization device of high viscosity polymer, belong to polymerization reaction device technical field.The present application includes reaction main body, with reaction inner cavity, reaction inner cavity is equipped with even root for stirring high viscosity polymer's helical stirring shaft, helical stirring shaft includes main shaft and the helical blade connected in the outer side of main shaft, and the helical blade in each adjacent two helical stirring shafts is staggered with each other on the side of mutual approach;Main shaft is equipped with the heat-conducting medium passage that is penetrated from top to bottom, and the heat-conducting medium passage in each main shaft is connected by connecting short pipe to be connected to be the serpentine heat-conducting medium circulation total passage, one end of heat-conducting medium circulation total passage is heat-conducting medium inlet, and the other end is heat-conducting medium outlet, and heat-conducting medium inlet and heat-conducting medium outlet are located in the same end of the reaction main body;Reaction main body outer side is equipped with heating box, and heating box is used to heat heat-conducting medium, and heating box is located in the side close to heat-conducting medium inlet and heat-conducting medium outlet.

The application discloses a kind of LDCT image reconstruction methods based on depth double-domain joint guide learning, comprising: the projection domain data of low dose CT obtained clinically is first reconstructed and recovered in projection domain network, simultaneously, only the projection domain data of being operated as guide is projected into image domain reconstruction network, realize the reconstruction operation of low dose CT, in addition, double-domain network also adopts a new structure, can better fuse local and global information.The application realizes the high-quality reconstruction of low-dose CT, effectively utilizes the data of original projection domain.The application not only proposes a new domain guide strategy, uses original projection domain data to guide the reconstruction of image domain, but also designs a new network module for fusing global and local information, which enhances the reconstruction effect of traditional double-domain model.

The application discloses a kind of wide distribution water-soluble ammonium polyphosphate and preparation method thereof, belong to compound fertilizer technical field.In the production of APP using water-soluble monoammonium phosphate and urea thermal condensation reaction, water-soluble organic matter is introduced, the chain growth window period before APP solidification is extended, and high water-soluble APP powder product with wide distribution of polymerization degree is obtained, so that the fertilizer grade APP product sequence is improved.Monamium phosphate pre-melting combined with APP cold return material process, the operation time is shortened, the production capacity is greatly improved, and the problem of wide distribution water-soluble product cannot be solidified is solved.The organic matter combined with phosphorus in situ in APP product has the potential of chelating trace elements in soil in addition to improving solubility.The method of rapidly producing wide distribution water-soluble APP powder in the application is simple in process, and is convenient for efficient scale production.
