因此，加快退耕還林還草，調整土地利用結構和產業結構，已成為實現山川秀美工程和可持續發展戰略的必經之路。論文以解決陜北地區的收入問題，植被問題以及糧食產量問題為出發點，首先從理論上分析了包絡分析方法在陜北地區退耕還林（草）中運用的可行性，然後結合陜北地區目前的實際情況，綜合分析出影響陜北地區退耕還林（草）的關鍵的七個因素作為輸入指標：水利水保設施投入，農作物投入，經濟林種支出，防護林支出，其它經濟作物，草類支出，畜牧業投入；以退耕還林所要解決的最終問題作為輸出指標： gdp收入、農民人均純收入、水土流失減少量、牧業總產值、糧食產量、林業總產值、其他經濟作物總產值。將各指標所對應的數據代入模型后，通過分析求解得出非有效的決策單元，再運用包絡分析方法的一些基本原理對非有效的決策單元進行調整，由此所得的數據對陜北地區的實際投入具有很好的指導意義。Used the identification of bandwidth point, a first - order - plus - dead - time model can be available. meanwhile a 4 - parameter model can be obtained with the two points. with the model available, the two - degree - of - freedom pid controller is designed based on the iae specification and a robustness specification
並利用臨界點的辨識與帶寬點的辨識建立二階純延遲模型，從nyquist圖可以看出，模型在對參數整定關鍵的一段頻率范圍內都能較好的擬和原對象。Conditions of normal mode realization are deduced and optimized model with the multivariate mode indicator function as the target function is built. through solving the maximal eigenvalue problem, the original shaker force vector of appropriation is reached. then the realization approach of the optimal shaker force vector based on single shape principle is proposed and at the same time the automatization of normal mode appropriation is realized
對于模態物理分離技術的多點正弦激振純模態試驗技術，尋求其最佳激振力矢量是最為關鍵的環節，本文先推導出純模態實現的條件，建立以多變量模態指示函數為目標函數的優化模型，通過求解最大特徵值問題，得出適調純模態的初始激振力矢量，再提出以單純形原理為基礎的最佳激振力矢量的實現方法，同時也實現了純模態適調過程的自動化。They have excellent corrosion, thermal shock resistance and spalling resistance. they wide applications and can be used in key locations of thermal processing equipment such as bof, eaf, lf and so on. 2 alumina - magnesia - carbon brick made from high - purity bauxite or fused alumina and fused magnesia grain or high purity magnesia by pressing, resin - bond for thermal shock resistance
1 ，鎂碳磚是不燒的耐火材料，經過摩擦壓磚機的成型以及乾燥處理后而成，它的主要原料是電熔鎂，高純鎂砂和高純石墨，結合劑為樹脂，鎂碳磚有良好的耐侵蝕性，熱震穩定性和抗剝落性，它已經被廣泛地用在鋼廠的轉爐電爐鋼包精煉鋼包等關鍵部位。This paper analyses the developing direction of cad system in the era of internet, discusses several key technologies of web - based cad system, including system architecture and developing tactics, the web - relevant network technology, pure java technology, web component model technology, web - based technology of graphics interactivity and system maintaining & upgrade technology, etc. through combining above relevant technologies, a web - based cad prototype system, wcs, is designed and implemented. as a system for verification, wcs possesses the functions of dynamic version update and web - based graphics interactivity between distant hosts, besides the basic functions of traditional cad softwares
