摘要將飽水軟土地基視為兩相介質，考慮水的滲流和土骨架變形的耦合作用，用間接邊界元法分析層狀飽水軟土地基中橫向受荷群樁動力阻抗，探討飽和土中孔隙流體對飽和土中橫向受荷群樁動力阻抗的影響。J22 well area geology condition is superior, forward modeling, earthquake attribute analysis, seismic phase analysis, wave impedance inversion are applying to the qualitative analysis and the rational description to the sand three center 3 granulated substance groups reservoir on the basis of the achievement of utilizing geology, well logging and mud logging combined with fine structure research, advantageous belt of the development of lithologic trap has been pointed out and the very good effect of detecting the position of exploration well has been obtained
摘要j22井區地質條件優越，在充分利用地質、測井、錄井等成果的基礎上，應用模型正演、地震屬性分析、地震相分析、波阻抗反演、三維可視化等技術，對沙三中3砂組儲層進行了定性分析和定量描述，結合精細構造研究，指出了構造巖性圈閉發育的有利區帶，落實了勘探井位，取得了很好的效果。After some correction of the apparent reflection coefficient, the extent of wave impedance differences of the reflection interfaces can be analysed quantitatively and, on such a basis, the defective position of the pile body can be detected
將視反射系數經過一定的校正後，可定量分析反射界面的波阻抗差異的大小，進而確定樁身缺陷的嚴重程度；反射波往返時則用來推算樁身缺陷的位置。This becomes increasingly critical as systems are being designed to combine circuits operating at lower power ( implying higher impedance levels ), higher speed ( implying lower nodal stray capacitance, faster edges, and higher frequencies ), and higher resolution ( much less output noise permitted )
當今的電子系統常常包含著低功耗（意味著阻抗更高） 、高速度（節點寄生電容更小、信號邊沿更陡峭、信號頻率更高）和高分辨力（噪聲容限更小）等電路，因此這個問題尤其應該引起重視。As the most effective means to eliminate current harmonics, active power filer ( apf ) can compensate dynamically harmonics whose frequencies and amplitudes vary ; moreover, its compensation characteristics is immune to the impedance variation of utility
有源電力濾波器是抑制電網諧波的有效措施之一，這種濾波器對頻率和幅度都變化的諧波進行跟蹤補償，且補償特性不受電網阻抗的影響，因而受到了廣泛的重視。When the body suffered from malignancy, on the one hand, tumor restrained cell immunity function, antibody ' s production and the body ' s immunity effect through inducing restraining t cell, so it accelerated tumor ' s growth, on the other hand, tumor induced body fluid restrained gene, which prevented t cell and nk cell from killing tumor and restrained lymphocyte to mitotic multiplication reaction, indeed it accelerated tumor ' s growth
當機體一旦患上惡性腫瘤后，一方面腫瘤通過誘導抑制性t細胞，抑制細胞免疫功能及抗體的產生，抑制機體對腫瘤的免疫效應，從而使腫瘤逃逸機體的免疫監視，促進腫瘤的生長。另一方面，腫瘤通過誘導體液抑制因子阻止t細胞和nk細胞的等對腫瘤的殺傷作用，抑制淋巴細胞對有絲分裂原的增殖反應，甚至促進腫瘤的生長。The pile group and the surrounding soil are discretized into horizontal layers, which meets a plane strain assumption. by means of that the single pile dynamic impedance is developed with a transfer matrix method, the pile - to - pile dynamic interaction factor is derived. then, the dynamic impedances of rigidly - capped pile groups with due consideration to pile - soil - pile interaction for vertical oscillations are produced
本論文充分考慮土的成層性和沿深度有變化的特性，將土層沿深度離散形成一系列均質的土層，各土層視為滿足平面應變假定，應用傳遞矩陣法推導出單樁在成層地基中的動力阻抗；並據此研究了在成層地基中的樁-樁動力相互作用因子，然後推導了群樁剛性承臺豎向動力阻抗。分享友人
