Abstract : based on the conceptual two - flow model and pic numerical solution method developed in the companion paper, the present paper further investigate the model application in simulation of the typical debris flows. the model validation was carried out with the experimental data obtained by other investigators at dongchuan debris flow observation and research station in yunnan province. predictions were made in terms of the main controlling facetors including the channel slope, flow density and time interval between two blasts of debris flows. the predicted results could well reflect the observations reported by the geographers and sedimentologists
文摘:採用文獻[ 1 ]中提出的陣性泥石流運動與堆積的歐拉-拉格朗日模型，模擬了陣性泥石流的運動過程和堆積形態，得出了與地學研究中觀測結果較為一致的認識.文中針對影響陣性泥石流的關鍵條件，重點通過改變密度，坡度和各陣泥石流的時間間隔等參數，分析了這些參數變化對泥石流運動及堆積規律的影響，提出了簡化分析整個陣性泥石流的條件.研究表明，應用經試驗資料驗證的數學模型不但可以方便、快捷地定量描述陣性泥石流的一般特性，而且能夠提供關于陣性泥石流運動及堆積的更多細節The exact design methods of switched - current filters are summarized, such as the director synthesis of z - plane, euler mapping, state variable analysis, matrix decomposition, and signal - flow - graph simulation of the lc and switched capacitor prototypes. at the same time, a modified left decomposition matrix method is proposed to overcome the usual problems of large silicon area, high sensitivity and component spreads by minimizing the input circuits. examples of switched - current low - pass, high - pass and band - pass filters are given to verify the feasibility of these methods
總結分析了實現高精度開關電流濾波器設計的各種實用方法，包括z域綜合法、歐拉映射法、模擬無源lc網路和開關電容網路的狀態變量法、矩陣分解法和信號流圖轉置法，並對左分解法加以整理改進，提出一種更為簡潔的設計結構，通過減化輸入電路克服一般電路中存在的佔用矽片面積大、靈敏度高等問題。
