摘要
从时域和频域上分析了油品扬沸火灾前兆燃烧微爆嗓音的特性，并将其与油水层热物理过程进行相关分析，提出了扬沸现象发生的基本条件，说明了利用扬沸前兆噪音监测预报扬沸火灾的理论基础．
The characteristic of premonitory combustion explosion noise during the process of boilover phenomenon in oil fires is analyzed in time and frequency domain, and its relations with the thermal process of oil-water layer are also studied. The basic conditions of the occurrence of boilover phenomenon have been submitted, and the fundamental theorical basis of monitoring and predicting boilover fire are presented in thes peper.
