This disquisition aimed at plc reactive dispatch curve controller, associating the entire exploiting process, expounded in guiding ideology, control standard, function and structure design, software system design, analog experiment, fixing and debugging and so on, also part of flow schematic diagram ( the ladder chart was n ' t drawn because of too many network and length limit ). this design involves many subject such as power systenu automatic control microcomputer control and electroa during the design, we have read a great deal of concerned data, base on the sufficient investigation analysis and research, associating the practicality of huanren power plant, we introduced and exploited plc reactive dispatch curve controller in the first time
本文針對plc無功調度曲線控制器，結合整個研製過程，在設計指導思想、控制準則、性能設計、裝置構成設計、軟體系統設計等方面進行了闡述，並給出了部分程序流程簡圖（由於梯形圖網路數太多，受篇幅限制沒有給出） 。本設計涉及到電力系統、自動控制、微機控制、電子等多學科知識，在設計過程中，我們查閱了大量相關的資料，在充分調查、分析、研究的基礎上，結合桓仁發電廠實際情況，首次提出並研製出了plc無功調度曲線控制器。Let be continuous and nonnegative on the closed interval. then the region bounded by the graph of, the - axis, the vertical lines, and is called the trapezoid with curved edge
設在區間上非負、連續，由， ，以及曲線所圍成的圖形稱為曲邊梯形，其中曲線弧稱為曲邊。Trapezoid curve method is adopted for frequency control of stepper motor. and a rough speed control method of servo motor is developed. kinematics modeling of rover in manipulation is presented
控制系統軟體部分採用梯形曲線對步進電機進行升降頻控制，同時實現了對舵機的近似速度控制。Several influence factors to result plasma drift in hainan were analyzed. in this paper the characteristics of ionospheric parameters variation were analyzed systematically and some new results in storm - time such as seasonal behaviors were obtained ; it is the first time to investigate the ionospheric drift behavior in hainan and some new results was obtained, the relationships between each two plasma drift velocity components in storm time in hainan were found and the electric filed variation in hainan ionosphere also was obtained ; the results also show that there are big differences of the ionosphere parameters bo and bl obtained from the data with that obtained from the iri - 2001 applied for hainan ; a new phenomena was found during a strong magnetic storm, that a layer with very strong electron density and density grad was found during the recovery phase of the storm, its horizontal scale is beyond 100km and temporal scale is about 2 hours, this phenomena repeated 3 times continuously. a type of negative disturbance in high and low latitude but positive disturbance in east - asia also has been found
本文較為系統地給出了海南地區電離層的參數變化特徵，特別是得到了一些暴時與以往不同的季節特性；第一次給出了海南地區的電離層等離子體漂移特徵，發現等離子體漂移暴時擾動在三個方向上有內在的聯系，得到了電場變化曲線；研究結果還表明海南電離層的半厚指數和形狀參數等與國際參考電離層iri - 2001存在很大差別；通過對強磁擾動事件期間的參數變化特性分析發現，在磁暴恢復相期間海南地區電離層底部存在一個電子密度非常大的高密度區，高密度區底部電子密度梯度隨高度急劇增加，該區域的水平尺度可達100公里以上時間尺度約為2小時，連續出現過三次，這是一個在海南從來未發現的新現象；研究還發現了暴時東亞地區電離層擾動會出現高低緯負相而中緯正相的現象。Photography - sensitometry of screen film systems for medical radiography - determination of sensitometric curve shape, speed and average gradient
