中文摘要：

为了更好地澄清畸变产物耳声发射（distortion product otoacoustic emissions，DPOAE）的产生机制，本文对相关研究进行了综述。一般而言DPOAE的产生机制包括产生源和传输途径两个问题，文中对DPOAE产生源所涉及的三种假说及DPOAE传输途径所涉及的两个假说进行了详细的论述和分析。

英文摘要：

In order to clarify the generation mechanism of distortion product otoacoustic emissions （ DPOAE）, this paper reviewed the research about DPOAE generation mechanism. Generally two important parts were included in the DPOAE generation mechanism, DPOAE generation source and DPOAE propagate pathway. Three hypothesis about the DPOAE generation source and two hypothesis about DPOAE propagation pathway were discussed and analyzed in the paper.
