摘　　要：本文对应用ＡＲ模型进行心音信号三维分析研究中的几个问题进行了探讨，确定了进行心音三维分析时所用ＡＲ模型的阶次、采样频率和时间段长度，并对心音信号与周期迭加的几种方法进行了比较。This paper discussed the several questions in research on the three dimensional analysis of heart sounds applying AR model. The order, sampling frequency and the length of time segment of AR model were determined and several methods of periodic average of heart sounds were compared.
