The asinh() function returns the inverse hyperbolic sine of a number. 函数的作用是:返回至各指定数值所对应的反双曲正弦值。
By means of inverse Fourier transform technique and convolution theorem, the semi-analytical solution for the velocity response of a pile undergoing half-cycle sine pulse at the pile head is obtained in the time domain. 在此基础上,利用Fourier逆变换和卷积定理,求得了半正弦脉冲激励作用下桩顶速度时域响应的半解析解。
