Color flat-panel plasma display panel (PDP) has many because of its excellent performance, becoming the most promising one color monitors. To improve the performance of PDP, the PDP with the three primary colors phosphor research is essential. Preparation of high-temperature solid-state green phosphor BaA112019: Mn2 + industrial production is the first choice. However, due to its uneven preparation of the phosphor particles, the easier reunion, poor dispersion of shortcomings. So that it can not meet the requirements of display technology. The high temperature solid-state papers prepared by starting the PDP high-intensity green phosphor BaA112019: Mn2 +. Experimental and parallel-law and two orthogonal experimental design the best method of treatment after the experimental conditions were chosen. Found that small molecule acid solution, ultrasound treatment, powder and solvent than are listed on the phosphor of the existence of impact. PDP phosphor through the test system testing Phosphor Properties, environmental scanning electron microscope observation and took the phosphor grain size and morphology, the average particle size analysis to measure the average size of the phosphor, X-ray powder Crystal diffraction (XRD) phase of the powder form. Results from the analysis, after handling the powder, its luminous intensity, size, dispersion and stability, have been greatly improved. Compensate for the high-temperature solid-state prepared by the green phosphor BaA112019: Mn2 + deficiencies. Key words: green phosphor post-processing orthogonal experimental design Properties

Abstract Analysis of the paper, as well as through the project from design to development of the whole process in detail to the construction of Signals and Systems Laboratory Information System of the entire process. The system ASP (Active Server Pages) scripting environment, the use of Access database to create dynamic Web pages to generate Web applications. Comprehensive utilization of the press release system modules, on-line exchange of modules, the report module, uploading and downloading of the ASP module, such as commonly used sub-modules, each module through the interface between the system to achieve better dissemination of information, feedback, reports information submitted and user functions. At the same time, the background of the management system module was designed so that system administrators can easily and quickly on the system management. In addition, this article also use photoshop, flash and other software to do the necessary material page narrative. Finally, this paper, the latter on the system expansion modules, management development and security permissions to improve and optimize the performance of the analysis done.

Activity based costing is a cost based on activity calculation method, refers to the work as the indirect costs, by confirming, calculating resource drivers, collection resource costs to the homework, then confirmed bycalculating activity drivers, products or indirect cost allocation method for imputation customer operation cost to go up. As China's manufacturing enterprises gradually to the diversification of product architecture, processcomplexity, the traditional cost accounting method has been unable to meet the needs of enterprises, in order to adapt to the modern manufacturingenvironment and management needs to emerge as the times require, with the basic concept of the operating cost method and principle of this paper, the operating cost method by different drivers, can allocate reasonable manufacturing costs. Another analysis of theapplication of ABC in our country manufacturing industry, through caseanalysis between ABC and the traditional cost method, finally put forward some suggestions to push the activity-based costing method.

colored plasma flat-panel display (PDP), because it has many fine performance, becomes most has one of prospects for development colored monitors. Must enhance PDP the performance, uses three primary color luminous powder to PDP the research to be very important. The high temperature solid phase legal system prepares green luminous powder BaA112019:Mn2+ is the present industrial production first choice. But because its preparation's luminous powder pellet non-uniform, easy to reunite, the dispersivity badly and so on shortcomings. Causes it to be unable to achieve the display technology the request The present paper uses the high temperature solid phase legal system to prepare embarking light intensity high PDP to use the green luminous powder BaA112019:Mn2+. And passed the parallel cut-and-try method and the orthogonal experimental design two experimental techniques has carried on the choice to the best post-processing experimental condition. Discovered that the small molecular acid solution, supersonic processing, the resolver and the powder body compare the row to the luminous powder various performance existence influence. Crossed the PDP luminous powder test system test luminous powder the illumination performance, under the environment scanning electron microscope observes and has photographed the luminous powder grain size and the appearance, the average grain diameter analyzer determination luminous powder's average grain diameter, the X- beam powder crystal diffractometer (XRD) determined the powder body's phase constitution. Obtains from the result analysis, the powder body after the post-processing, its luminous intensity, the particle size, the dispersivity, the stability, obtains improves greatly. Made up the high temperature solid phase legal system to prepare green luminous powder BaA112019:Mn2+ the insufficiency. 绿色荧光粉 Green luminous powder后处理 post-processing正交实验设计 orthogonal experimental design发光性能illumination performance

The colour plasma flat display (PDP) has a lot of good function because of the person , becomes one of the colour display developing a prospect have most. Need to improve the PDP function, the research using three primary colours fluorescent powder to PDP is all-important. High temperature strengthen method of physiognomy preparation green fluorescent powder BaA112019: Mn2 + is that the commercial run head elects at present. But since whose the preparation fluorescent powder pellet is uneven, exchange birdnesting , the disperse low grade shortcoming. Make the person have no way to reach the request demonstrating a technology's. The thesis adopt capital high temperature strengthen method of physiognomy preparation starting off with green fluorescent powder BaA112019 up higher PDP of intensity: Mn2 +. And know the experiment law and orthogonality experiment of equal rank designing that two kinds experiment method have carried out choice on the best post-processing experiment condition. Discover the sour small molecule solution , surpass sound treatment , menstruum and the powder body than every there exists effect in function column all to fluorescent the fact that PDP fluorescent powder tests the system testing fluorescent powder luminescence function, the environment scanning electricity has observed and shot fluorescent powder crystallite dimension and shape appearance under the mirror, the average grain size analysis instrument determines average fluorescent powder grain diameter , the thing determining the powder body composes the X-ray powder crystal diffraction instrument (XRD) each other. Secondary result analysis gets , powder experiences and observes the course post-processing, whose luminescence intensity , grain diameter , disperse , stability, get bigger improvement. Reparation high temperature strengthen method of physiognomy preparation green fluorescent powder BaA112019: Mn2 + deficiency. Keywords: The green fluorescent powder post-processing orthogonality experiment designs the glowing function
