摘要(Abstract)：
简介了频谱分析的基础理论和快速傅利叶变换 (FFT)算法。以FFT为基础 ,开发了频谱分析用的软件 ,分别对小规模台阶钻孔爆破、大规模高台阶深孔微差爆破以及硐室爆破产生的地震波的频谱进行了分析 ,并探讨了这些频谱的特征
Basic theory of spectrum analysis and Fast Fourier Transform (FFT) algorithm are briefly introduced. On the basis of FFT, a software for the spectrum analysis has been developed. With this software, the spectrums of seismic waves from small scale bench, large scale high bench short delay and chamber blastings are analyzed and the characteristics of these spectrums discussed.
