摘　　要：开展落叶松原木楞堆的细水雾灭火试验,对施加细水雾前后的雾罩内、外典型位置的烟气变化规律进行相关性分析及回归分析。研究结果表明:施加细水雾前,原木楞堆产生的CO、CO2与空间残留的O2之间的体积变化在雾罩内外典型位置存在显著相关性;施加细水雾以后,雾罩内O2和CO2体积变化具有高度负相关性、CO和CO2之间具有高度正相关性、雾罩外O2和CO体积变化也具有显著的负相关性。Doing the water mist fire experiments on larch log pile and making correlation analysis and regression analysis on the exhaust gas＇s inherent law in the typical position after the log pile was applied with water mist.The research＇ s result shows that before applying water mist,the percentage variation of O2 left and the CO,CO2 produced by log pile which is gathered in the typical locations inside and outside the cover in the fog have relevance and regression equations to each other; after applying water mist,the volume ratio between O2 and CO2 has highly positive correlation inside the cover in the fog,the volume ratio between CO and CO2 has highly negative correlation inside the cover in the fog,the volume ratio between O2 and CO2 has highly positive correlation outside the cover in the fog.
