摘要
本文通过采用生物信号采集处理系统对不同发育阶段的虎皮鹦鹉的声音进行了分析.结果发现:(1)随着虎皮鹦鹉的成长,叫声越来越复杂,幅度越来越高;(2)在成长的过程中,雄鸟比雌鸟的叫声更复杂,但幅度不如雌鸟的高.
By Medlab biological signal collection and disposal system analyzing it and using paraffin method, we compare with Melopsitiacus undelafusp .on different development stage. The results were as follows ： （ 1 ） with the Melopsitiacus undelafusp growing up, the scale of song is more complex and higher ; （2） during this course, it can be seen the more complex song of male birds than female bird, but the scale is not higher.
