inverse frequency response
解釋
倒頻率應答-
Smart materials and structure have definite requirements of sensor components and driving components, for example, they can adhere well to the matrix and have higher strength, fatigue strength, more broad scope of frequency response and faster response speed, etc. piezodielectric ceramics have characteristic of easily preparing, heat - resistance, wet - resistance, high strength and broad scope of frequency response, etc. furthermore, it has piezoelectric effect and inverse piezoelectric effect, namely it can produce electric potential energy when it is transformed by mechanical strength and its mechanical dimension can be transformed when voltage is put on it
壓電陶瓷能與基體材料很好結合，具有制備容易、耐熱、耐濕、強度高、頻響寬等特點，另外它具有正壓電效應和逆壓電效應，即當它受到機械力變形時，能產生電勢，對它施加電壓時，能改變其機械尺寸，因此它在智能材料結構中既能用作傳感元件又能用作驅動元件。 -
The effect of the dust charging process becomes significant when the charging time is longer than either the pulse period or the ion response time ( measured by the inverse of the ion plasma frequency )
因為塵埃粒子的充電時間長于離子響應時間或者負脈沖時間，塵埃粒子的充電過程對鞘層的形成將有很大影響。 -
Thus the resistance factor and vibration modes of the soil layer are obtained and used to analysis the pile response. by considering the interaction between the soil layer and the pile with boundary condition of continuity of displacement and equilibrium of force at the interface of soil layer and pile, the dynamic equilibrium equation of pile is solved and an analytical solution for the pile response in frequency domain is yielded, which is used to define complex stiffness and mobility at the level of the pile head. based on the convolution theorem and inverse fourier transform, a semi - analytical solution of velocity response in time - domain subjected to a semi - sine exciting force is given
首先通過引入勢函數方法對土體位移進行分解，從而將土體動力平衡方程解耦，求解得到了土層的振動模態和阻抗因子，然後利用該解以小應變條件下樁土接觸面上力平衡和位移連續條件來考慮樁土耦合作用，求解樁的動力平衡方程，得到了樁頂的頻域響應解析解、復剛度和速度導納，利用卷積定理和傅里葉逆變換，求得了半正弦脈沖激振力作用下樁頂速度時域響應半解析解。
