Abstract: In this paper，the normal and frightened calls of the wi1d rhesus macaque (Macaca mulatta ) at Nanwan peninsula of Hajnan Island have been analyzed．
The norma1 and frightened ca1Is of the adult female and the yearling monkey are of a kind of harmonic structure．For the adult female，the subharmonic of high amplitude (SHHA_1,2) of the normal and frightened call are 300Hz，550Hz and 300Hz，1.2KHz respectively，and for yearling monkey，the SHHA_1,2，3 of the normal and frightened call are 300Hz，1KHz，2KHz and 350Hz，1KHz，3KHz respectively．In the acoustic structure，these calls are the composition of a periodic wave (PW ) and the high amplitude pulse train (HAPT)．The average period(T) PW remains 20ms all along．

摘要： 本文对海南岛南湾半岛野生猕猴的正常和受惊叫声进行了分析和研究：成年母猴与幼体正常和受惊时的叫声是一种谐波结构，其叫声的变化表现为谐波频数上不同的幅值组台。成年母猴正常和受惊叫声的高幅谐波SHHA_1,2 分别为300Hz、550Hz和300Hz、1.2KHz；幼年猴正常和受惊叫声的高幅谐波SHHA_1，2，3． 分别为300Hz、1KHz、2KHz和350Hz、IKHz、3KHz。SHHA₁是波形结构中周期波上叠加的低幅波动LAP在功率谱上的反映，而SHHA_2，3，是与波行中高幅阵脉冲列HAPT相对应的，波形结构中周期波的平均周期T始终保持一致为20ms。
