進一步根據(jù)樁土接觸面上的位移中文视频在线你懂的、應力連續(xù)條件hs网站，求解了樁身動力平衡方程，在頻域內得到了樁頂動力響應的解析解久久精品超碰。

According to induced response method, the expression in frequency domain of pressure response at the end of pipeline is derived using impulse response method and convolution theorem. The expression indicates that that transfer function is only related to the characteristics of pipeline system and the Fourier transform of flow variable only depends on the operating characteristics, and the pressure response in frequency domain is linear with the Fourier transform of flow variable.
