  1. The paper analyzes and summarizes the following laws of distinctive sediment yield produced in storm floods of the region based on predecessors ' study : storm is the main dynamic force of erosive sediment yield and storm, flood and sediment exist an inevitable relation ; the flood occurring time is concentrated with high peaks and huge volume, suddenly rising and suddenly falling and has decisive influence to the formation of a major flood peak in the middle yellow river ; the main reasons of concentrated coarse sediment of the river is severe erosive sediment yield, strong sediment transporting capacity and high sediment concentration ; the important influence of frequent or continued storm floods happened in he - long reach especially in coarse sediment concentrated region to the sediment transport of the yellow river and ; along with the increase of harnessing, regional flood trend is becoming smaller but the variation of sediment quantity is not obvious and the reaction of peak discharge and flood runoff of majority tributaries are not sensitive, showing that a general and normal engineering works can not effectively control regional major floods especially the sediment of an extraordinary flood

    摘要在前人研究的基礎上分析總結了該區特有的暴雨洪水產沙規律：暴雨是侵蝕產沙的主要動力，暴雨、洪水、泥沙之間存在著必然的關系；洪水發生時間集中，峰高量大，暴漲暴落，對黃河中游大洪峰的形成具有決定性影響；侵蝕產沙強烈而粗泥沙集中，輸沙能力強，洪水含沙量高，是黃河粗泥沙的集中來源地；河龍區間特別是粗泥沙集中來源區頻繁或連續的暴雨洪水對黃河輸沙有重要影響；隨著治理水平的提高，區域洪水有減小趨勢，但泥沙量變化不明顯，大部分支流的洪峰流量、洪水含水量反應不敏感，說明一般規模和水平的治理工程還不能有效控制區域大洪水特別是特大洪水的泥沙。

    摘要採用混酸體系（濃硫酸濃硝酸體積比為3 / 1 ）對單壁碳納米管進行了氧化處理，並通過氧化處理后在單壁碳納米管表面生成的羥基官能團與長鏈硅烷偶聯劑進行反應，制備了表面有機修飾的單壁碳納米管。
  4. Then the solving procedures of these bies by the rwg functions based moment method are elaborated, and the method of modeling complex objects built of arbitrary line, surface and volume structures is developed. in order to solve realize antenna and circuit problems, methods of adding excitations and concentrated loadings with moment method are deceloped, and matrix pencil ( mp ) method is used to deembeded the s prameters of antennas and circuits from the computed current distribution. some numerical results of practical complex antenna and scattering problems are presented to illustrate the veracity and effectiveness of the method

    在第一部分中，首先從電磁場的基本理論出發，基於等效原理和邊界條件以統一的方法建立了用於分析金屬、介質及金屬與介質混合結構的邊界積分方程，並歸納和比較了各類積分的適用范圍和優缺點;在此基礎上，給出了使用基於rwg函數的矩量法求解各種邊界積分方程的一般過程;研究了具有任意線、面、體組成的復雜結構的電磁建模方法，並給出了各種多面連接情況下基函數和未知量的選取方法;研究了使用矩量法分析電路、天線問題時集總元件和激勵源的處理方法，並基於矩陣束方法（ matrixpencilmethod ）提取了電路和天線問題的s參數;最後通過分析一些工程中的復雜金屬天線問題和具有「金屬與介質混合結構」的散射和天線問題驗證了方法的準確性和高效性。
