持续监测血流动力学指标，记录心电图并进行心率变异功率频谱分析（HRV - PSA）；
Using power spectral analysis, centennial and millennial-scale cycles of Paleo-monsoon were extracted. In the cycles, 71 a is the basic cycle of East Asian Monsoon.
应用功率谱分析的方法，提取出同时段百年尺度和千年尺度的古季风周期，其中71 a周期为本文首次提出，并被认为是东亚季风活动最显著的基准周期之一。
Traditional speech signal processing is based on FFT power spectral analysis, in noisy condition, the spectrum of noise and speech signal are processed in the same way.
传统语音信号谱特征的提取是基于FFT 的能谱分析方法，在噪音环境情况下，对噪音的频谱成分与语音信号的频谱成分的处理采用“平均主义”的原则。
