  1. To improve understanding of the processes of heterogeneous land surface - atmosphere interaction, the utilization of satelli te remote sensing is indispensadle. in this paper, with the aid of satellite remote sensing and fiend observational data which observed during intensive observation of huaihe river bain energy and water cycle experiment hubex in 1998, the surface albedo, ndvi normalized difference vegetaton index and surface temperature in regional scale of hubex could be derived. then, the distribution of regional energy balance components could be estimated. this wor provided the physical foundation for the numerical simulation of the huaihe river basin energy and water pro cesses, and is important for us to further analyze the regional distribution of surface characteristic parameters ad energy balance components with the change of the weather situation in hubex in 1998. our work is still in a developing stage, some methods of retrieval in the paper should be improved further

    利用1998年淮河流域加密觀測試驗hubex iop期間的資料，進行淮河流域能量平衡的參數化方案的研究，用noaa衛星的avhrr資料建立了試驗區地表特徵參數及能量平衡各分量的參數化方程，並對衛星遙感反演結果和試驗觀測值進行了對比，為淮河流域能量和水循環的數值模擬提供了物理依據。
  2. Secondly, grounded on the study of the distribution of the high external waterpressure and high geostress and the characteristic of the rock in engineering area, the paper built the elastoplastic fem numerical simulation model, and think over the procedure in tunnels excavation and the history of work of water load, and then get the relations between the different tunnels diameter, different permeability coefficient and depth of the grouting rock and the deformation, stress distribution and plastic range of the surrounding rock and support structure. finally, according to the modern design theory of tunnels construction, the particular design of country rock reinforcement and support structure are researched and presented for diversion tunnels

    接著，本文在深入研究工程區高外水壓力及高地應力分佈規律及巖體特性的基礎上，建立起高地應力、高外水壓力作用下隧洞圍巖結構非線性有限元模擬計算模型，然後考慮隧洞的開挖過程、水荷載的作用歷史，通過計算分析得出了不同洞徑、不同的灌漿圈滲透系數和不同的灌漿圈深度以及不同開挖過程與圍巖及支護結構的應力、位移和塑性區的關系。
  3. The distribution of stress and strain and the variety of blank thickness is analyzed during different forming stages of laminose stepped tubular part. the condition of one - off drawing of laminose stepped tubular part is obtained. plasticity theory and numerical simulation technology of finite element are applied synthetically to analyze the forming technological characteristic of stepped tubular part,

    通過綜合應用塑性力學理論、有限元數值模擬等手段成功地分析了階梯筒形件成形工藝特點，獲得了階梯筒形拉深的合理工藝方案及階梯筒形件一次拉深成形的規律，最後通過實驗檢驗對此工藝方案及規律進行了驗證，結果表明本文所提出的工藝方案及階梯筒形件一次拉深成形規律是正確可靠的，能直接用於指導生產。
  4. The numerical simulations of loading processes of flier - plates show that the loading history of the flier - plate designed with wave impedance as design parameter is significantly different from that of the flier - plate designed with density as design parameter and the former is expected to have better quasi - isentropic characteristic, which indicates that it is very essential to use wave impedance as design parameter directly to design the wave impedance distribution of flier - plate

    而以波阻抗作為設計參數，所得飛片的擊靶波形隨時間的變化更加平緩，有望獲得更好的準等熵壓縮性能。因此，直接採用波阻抗作設計參數，實現梯度飛片波阻抗分佈的精確設計是非常必要的。
  5. At the same time, the design of cascaded coupler with a given ratio distribution is proposed, which can lead to higher isolation by suppressing sidelobe. 2. according to theoretical analysis and numerical simulation, the interleaver can show flat - top and high isolation pass band characteristic when the two couplers " ratio is assigned to 15 percent

    2 .對全光纖反射式奇偶交錯濾波器進行了理論分析和數值模擬，發現當兩個耦合器的分光比均為15時產生了平頂高隔離度的通帶頻響特性，做了相關實驗，結果與理論分析基本符合。
