摘要： 通过搭建超大尺寸燃气爆燃实验平台，模拟居民住宅内燃气泄漏后的分布扩散，以移动传感器和固定传感器相结合的方式，采集了空间内燃气泄漏后不同位置的天然气浓度随时间的变化，总结了燃气在住宅内泄漏后自由扩散的规律。同时，通过构建浓度地图的方式，呈现了燃气泄漏后不同时刻厨房内的浓度变化。

关键词: 燃气泄漏, 浓度分布, 扩散规律, 浓度地图

Abstract: Through constructing a large- size experiment platform for gas explosion, the distribution and diffusion of gas leakage within the residential buildings were stimulated. By collecting data by the mobile and fixed sensors, the changes of gas leakage concentration in different positions over time were collected and the laws of gas leakage diffusion in buildings were summarized. Meanwhile, by building a concentration map, the changes of gas concentration in the kitchen at different moments after gas leakage were presented.

Key words: gas leakage, concentration distribution, diffusion laws, concentration map
