Both seismological theory and macroseismic observation show that the shape of strong motion response spectrum depends mainly on magnitude, distance of epicenter and engineering site condition.

地震学理论和强震观测都表明，强震反应谱的形状主要取决于震级、震中距和场地条件。

Firstly, in order to reduced the computational complexity, the magnitude spectrum of CW is divided into basic matrix, transitional matrix and supplemental matrix.

首先，为了降低计算复杂度，将CW的幅度谱分块处理，分成基本矩阵、过渡矩阵和补充矩阵。

Spectrum magnitude of an earthquake is an important source parameter of earthquake size in seismology research.

谱震级是表征地震强弱的量度，是地震学研究中的一个重要的地震参数。
