中文摘要：

双通道模型认为词汇阅读加工存在两条通道：词典通道和非词典通道。双通道模型可以解释大量的词汇阅读现象，如词频效应、规则性效应等，并得到了来自阅读障碍病人研究的支持。本文述评了双通道模型的发展过程，重点介绍了双通道交互激活模型的一般特点和运行机制（如正字法编码、语音编码和亚词汇正字法-语音转换加工等）及其相关研究。最后讨论了该模型的发展趋势。

英文摘要：

In dual-rout model, there are two routes about word reading： lexical and non-lexical routes. Not only can dual-rout model explain many phenomena about word reading, such as frequency effect, regularity effect, but also be supported by a lot of material researches from dyslexia. The paper commented on the development of dual-rout model, and introduced the general characteristics and mechanism of bi-modal interactive activation model （BIAM）, such as orthographic code, phonological code and sublexical orthogra- phy-to-phonology transformation, et al., which were supported by many relative experimental researches. Finally, the paper discussed the trend of BIAM in the future.
