本文指出汉语送气声母弱势倾向的三种表现及其在时空两方面体现出的“异动”现象。本文认为，送气声母在历时演变中的强倾斜性表现受到语音内部调节机制的作用，它起因于语音系统中不平衡的对立格局及其变化。语音内部调节机制很可能通过听觉心理起作用。

Three evidences of the inferiority of aspirated initials in modern Chinese are given out. Two reverse changes in history and dialects,however,are obvious. In the author＇s opinion,the reverse changes were resulted from the unbalanced contrast,and consonant confusion in phonetic perception provides the psychological possibilities.
