  3. The equations of motion governing the axisymmetric elastic deformation of finite orthotropic cylindrical shells, involving the effect of transverse shear and rotational inertia, are derived. by applying the reverberation method, the displacement and the resultant forces of the shell in the phase space are expressed. then the transient waves in the finite orthotropic cylindrical shell subjected to the axisymmetric impact are obtained by using inverse laplace transforms. furthermore, the transient solutions are decomposed to the generalized ray integrals and computed numerically

    分析了計及剪切變形和轉動慣性的有限長正交異性圓柱殼中彈性瞬態波的傳播問題，採用回傳矩陣法，在相空間中給出了位移和內力的表達式。再利用laplace逆變換，得到正交異性圓柱殼受軸對稱沖擊作用時彈性瞬態波解，然後將其分解為若干廣義射線積分之和，並用數值方法求解之。
  4. He became a soloist with the boston public school orchestra, and for 13 weeks in 1934, played classics on the radio

    后來他更在波士頓公立學校管弦樂團內擔任獨奏者，並於1934年時，在廣播中演奏古典樂曲長達13個星期。
  5. And pays emphasis on analyzing the system structure and system flow, the core techniques, the channel characteristic and parameters of dvb - t system. the system adopts some core techniques such as cofdm, a lot of tps ( transmission parameter signalling ) insert and guard interval, and so on. so it can withstand high - level ( up to odb ), long delay static and dynamic multipath distortion

    論文首先描述了數字電視地面廣播的需求條件，技術難點和目前存在的問題，並重點分析了dvb - t系統結構流程，核心技術及系統通道特性和參數，該系統採用了cofdm （編碼正交頻分多路復用） ，大量導頻信號插入和保護間隔技術等核心技術，使之能抵抗高電平（ 0db ） ，長延時的靜態和動態多徑失真，有利於數字和模擬電視的混合傳輸，它的多載波調制模式功能和性能在移動和便攜接收、同頻網等方面具有獨特的優勢。
  6. Stoneley wave is a kind of guide waves propagating along the liquid - solid interface in well. when a sonic beam strikes the surface of a thick plate immersed in a liquid, a stoneley wave is generated. stoneley wave approach is applied on analysis of well logging more and more widely in recent ten years with the introduction of advanced analysis methods for component waves from full - waveform array acoustic log data. the spectrum of stoneley waves are used to identify the fractured zones and quantitatively calculate the fracture parameters of reservoirs, especially to evaluate the validity of fractures at fracture - type complex reservoir

    斯通利波是一種沿井壁傳播的聲波，當聲波脈沖與井壁和井內流體的界面相遇時就會產生斯通利波。近十幾年來，由於長源距和偶極子陣列聲波儀在測井中的廣泛應用和全波形陣列聲波測井資料中各組分波的處理分析方法的進步，可將斯通利波分離出來單獨研究並應用於測井資料分析。斯通利波技術是評價裂縫及其滲透性的有效方法。
