反应谱形状 meaning in English

shape of response spectrum

In this part , response spectrum and fourier amplitude spectrum are studied , the main results are as follows : 1 ) response spectrum analysis : a ) absolute acceleration response spectrum ( sa ) : ( 1 ) in general , response spectrum decrease with depth , for m < 4 . 5 , the shape and the predominant period of each response spectrum in different depths are similar : the variation of spectra with depth focus on near - surface level ; the normalized spectra are similar to each other , except the predominant perk value in middle depth of some earthquakes is higher than other depth
地震动反应谱沿深度变化的规律( l )加速度反应谱( s 、 )沿深度的变化规律一般，加速度反应谱( s 。 )随深度的增加而减小。震级较小时，不同深度各测点的反应谱形状很相似，卓越周期基本一致;浅层处反应谱沿深度的变化梯度较大;深层处反应谱大小比较接近;强震时，反应谱形状在短周期有较小差别，长周期逐渐接近。
