在洪水區域分析中一般採用洪水指標法，但該法的基本假定與實際情況存在矛盾，因此本文採用一種新的分析方法? ?標度分析法（或稱為分形分析法）來研究洪峰的區域變化，將標度不變性引入年最大洪峰流量? ?匯流面積關系中，並將其用於嘉陵江流域的洪水，另外，本文在smith提出的具有標度性質的二參數對數正態分佈模型基礎上創造性地提出了三參數對數正態分佈模型來表徵年最大洪峰流量分佈中匯流面積的尺度影響。First, according to the demand of vimp for resin system, the reaction kinetics and rheological of up resin are investigated and the optimal content of low additive profile ( lpa ) is determined. then vimp based on a high - permeable medium and grooves are studied by visual experiments, through which the appropriate high - permeable mediums are selected and the parameters of width, depth and spacing for flow grooves and spacing for supply grooves are optimized. furthermore, various factors affecting the mold filling process are discussed and the whole vacuum infusion procedures are described taking examples of the manufacture of a model boat and a sandwich panel in one infusion
文中首先根據vimp對樹脂體系的要求，對vimp用不飽和聚酯樹脂體系的動力學和流變學性能進行了研究，確定了最佳低收縮添加劑的含量；對高滲透介質型和溝槽型vimp開展了實驗研究，通過可視化實驗優選出較好的高滲透介質，確定了引流槽的寬度、深度和槽間距及主槽的槽間距等工藝參數並進行了優化；對影響充模過程的各種因素進行了詳細的討論，並以模型船和夾芯面板的製作為實例描述了兩種vimp的成型過程；在實驗的基礎上，建立了二維滲漏模型，採用控制體有限元法對高滲透介質型vimp進行了成型過程的計算機模擬計算，通過充模時間和流動前峰的計算值與實驗結果的比較，驗證本文所採用的數學模型和數值方法的正確性，其結果對實際生產具有一定的理論指導意義。The result shows that, the size of the coupling port has strong influence on the external quality factor of the output cavity, while the size of the coupling line and the capacitive metal rods mainly affect the tuning frequency of cutoff waveguide filter
另外，由於耦合接頭相當于在截止段中引人了一個附加電感，這使濾波器諧振電路的品質因數變大，諧振峰變窄。The equation among peak factor, quality factor, switch initial angel is concluded. on the basis of the equation, peak factor curve has been programmed. the rms value, peak value and switch initial angel can be shown in the screen of computer
本文推導峰值系數與品質因數和合閘初相角的函數關系式，依此編制峰值系數曲線程序，利用對品質因數和合閘初相角的控制可使每個繞組都受到規定峰值的作用。Cassava root is used for carbohydrate source in tropical region. quality of cassava starch is variable and affected by many factors. an attempt was made to evaluate the effect of peeling, washing and drying on starch purity and starch paste viscosity. paste viscosity were based on results of rapid visco analysis ( rva ). the results of this study revealed that : peeling, washing and drying temperature significantly affected cassava starch purity and starch paste viscosity. the starch from unpeeling root had a dullness color, but had higher peak viscosity, trough, final viscosity, breakdown and setback than that of starch from peeling root. more washing not only increased starch purity, but also improved starch past characteristics, such as peak viscosity, trough, final viscosity, setback and pasting temperature. different drying temperature had no effect on starch whiteness. starch purity had a little increase with drying temperature increasing. in general trend, starch dried at higher temperature had higher peak viscosity, trough, breakdown, final viscosity and higher setback
木薯在熱帶地區是碳水化合物的主要來源.木薯澱粉的品質受許多因素的影響.本項研究著重探討澱粉提取過程中，削皮、水洗、乾燥溫度對澱粉純度、白度和澱粉糊化粘度的影響.結果表明，未削皮的澱粉樣品色發灰，但具有比削皮處理高的峰值粘度、 95最後粘度、 50時粘度、峰值降和持久性.增加水洗次數，不但能增加澱粉純度，還可提高澱粉高峰值粘度、 95最後粘度、 50時粘度、持久性和糊化溫度.不同乾燥溫度對澱粉白度無影響，但澱粉純度隨乾燥溫度的提高而稍稍增加.通常高的乾燥溫度有高的峰值粘度、 95最後粘度、峰值降、 50時粘度和持久性分享友人
