Through semicontinuous polymerization technology, emulsion polymer nanoparticles with a multilayer shell structure can be synthesized, and the product has the advantages of small particle size, narrow particle size distribution, relatively high solid content, low emulsifier using amount, and the like, and has good application prospects in industrial production.

The invention relates to a capping material for treating lake eutrophication in situ and a preparation method thereof. More specifically, it is a capping material for removing nutrient salts such as soluble phosphate in eutrophic lakes and a preparation method thereof. It belongs to the technical field of environmental protection treatment. The capping material of the present invention has the composition and weight percentage as follows: 1. natural carbonate rock or calcium industrial by-product is 65-70%; 2. rare earth tailings cerium salt or lanthanum salt or its rare earth oxide is 10-15% ; ③ inorganic cement material cement, lime, or gypsum, or organic polymer binder is 15 to 25%. The above raw materials were stirred and mixed at 20° C., washed, filtered, and dried to finally obtain a granular capping material. The capping material can absorb a large amount of soluble phosphate and other nutrients in the water body to form insoluble compounds, and sink to the surface of the mud. The capping material can self-form a layer of blocking adsorption layer, preventing the release of the phosphate that pollutes the bottom mud of the water body to the upper water body.

The invention discloses a GIF file rendering method, comprising: reading the GIF file by adopting a streaming reading method; decoding the read GIF file and obtaining a decoded frame picture; rendering the obtained frame picture; judging the obtained Whether the number of frame pictures reaches the predetermined number, if yes, then end the rendering; otherwise, return and execute the step of decoding the read GIF file and obtaining the decoded frame pictures. The invention also discloses a GIF file rendering device. Compared with the prior art, the GIF file rendering method and device provided by the present invention read GIF files using a streaming reading method and render them on demand, which reduces resource occupation and improves the efficiency of playing GIF animations. The problem of excessive resource occupation caused by reading GIF files in the prior art is solved.

The access device includes: two-way E1 interface, eight-way optical fiber interface, central processing unit CPU and field programmable logic gate array FPGA; the two-way E1 interface is respectively connected with the A control device and the B set control device of the control substation; the eight-way The optical fiber interfaces are respectively connected to eight control terminals; the FPGA includes eight groups of optical fiber transceiver modules and two groups of E1 transceiver modules, the eight groups of fiber optic transceiver It is connected with two E1 interfaces, each group of optical fiber transceiver modules is equipped with a reset sub-module, and each group of E1 transceiver modules is equipped with a reset sub-module; the CPU is connected to the FPGA through a parallel bus. This solution can be applied to actual projects, and can improve reliability, save investment costs, and reduce maintenance difficulty while solving the problem of excessive communication bandwidth occupation in conventional security and stability control system solutions.

The present invention relates to one kind of capping material for in-situ stabilizing polluted bed mud and its usage, and belongs to the field of environment engineering technology. The new-type capping material is spherical granular material in a three-layer structure, which includes one core layer of natural inorganic inert aggregate, reactive inorganic aggregate, etc and accounting for 15-35 wt%; one middle sealing layer of phosphate rock, carbonate rock, natural elite, etc and accounting for 60-80 wt%; and one outer protecting layer of cement, lime, gypsum, polymer adhesive, etc and accounting for 1-5 wt%. When it is used, the capping material is thrown to the surface of polluted bed mud, and after some time, it forms one blocking and adsorbing layer by means of expansion and adhesion to separate the polluted bed mud from the upper water and to degrade and decompose the pollutant.

The invention relates to an oral self-emulsifying drug delivery system of RhizomaChuanxiong oil; the system uses RhizomaChuanxiong oil as the oil phase, and solves the problem that the surface active agent dosage is too much owing to excessive volume of the oil phase. The system comprises RhizomaChuanxiong oil, co-emulsifier and surface active agent, which can effectively improve the bioavailability of RhizomaChuanxiong oil and medicine taking is very safe and convenient. The invention also provides the preparation method for RhizomaChuanxiong oil, including the following steps: mixing the RhizomaChuanxiong oil as the oil phase and the corresponding surface active agent and co-emulsifier according to a certain ratio to form medical solution, thus forming the RhizomaChuanxiong oil oral dilution medicine system. After being taken in, the medical solution is mixed with the water in the gastric juice and then together turn into emulsion under gastric motor, thus improving the bioavailability and treatment efficiency. The preparation method of the invention dilution medicine system is simple, and the medical solution can be made into soft capsule, hard capsule or other oral dosage forms; The invention has low cost, and reliable performance, which is convenient for storage and transportation.
