  2. Water pressure method can distinguish permeability of concrete with different strength or air content, and penetration length or permeability coefficient has good correlation with chloride ion diffusion coefficient. tension method also can distinguish permeability of different concrete, but it has discreteness compared with water pressure method

    通過研究水壓法對于不同滲透性混凝土發現:水壓法能夠較好的區分不同強度、不同含氣量的混凝土的滲透性,滲透高度及滲透系數與氯離子擴散系數的相關性較好。
  3. In the laboratory, it has been found that the incorporation of straw into the soil increased the coefficient of saturated soil penetration, thus the macro - porosity of soil

    實驗室測定表明,在土壤中加入稻草可以增加土壤的飽和透水系數,這說明土壤的大孔隙增加了。
  4. Changing the depth of penetration of the three dowels results in the variation of the reflection coefficient ( s1 1 ) at the port 1. using matlab, we can calculate different equivalent impedance of port 1 which resulted from the variation of dowels depth. the purpose of my work strike up a relationship between the depth of dowels and equivalent impedance at port, thereby accomplish matching rapidly, simultaneously and stably

    在構建了自動阻抗匹配系統的基礎上,本文提出了一種新的快速匹配方法;此方法是將模擬軟體hfss和系統設計相結合,用hfss模擬系統中完成阻抗變換作用的銷釘匹配器,獲得銷釘插入波導深度變化時的埠等效特性,並將模擬得到的數據用matlab組織起來,分析銷釘插入波導的深度變化時埠等效阻抗特性的變化,來達到對調試變化規律的認識,快速的實現銷釘插入深度與反射系數間的統一。
  5. Adopting the deformation harmony theory, the numeric calculation of the curve of load versus settlement is made. the fitting results between the calculated curve of load - settlement and the measured one of piles with different construction process are illustrated. hence, under the condition of few or no static load test data, the performance of bearing capacity of single bored pile in loess may be predicted utilizing indexes of shear wave velocity, static cone penetration test and modification coefficient of depth, so it is remarkable to reduce the blindness of preliminary design of pile
