引入结构屈服水平系数，建立了结构的延性需求谱，使地震动的幅值特性和频谱特性可以分开考虑。
By introducing the yielding level factor and constructing the ductility demand spectrum, the characteristic of peak values and frequency contents of ground motions are considered separately.
边界层温度和风速的垂直结构也会影响到水平风速低频谱的垂直分布。
The vertical structures of temperature and wind in the boundary layer also have an effect on the vertical distribution of low-frequency spectra of horizontal wind velocity.
这种方法在对角线方向上的频率响应特性较好，而在水平和垂直方向上对基带外的垂直频谱衰减不够，导致放大图像中的方块效应。
But there is Mosaic impact in the enlarged picture because this method can't adequately attenuate the vertical frequency off the Base Band in the horizontal and vertical direction.
