摘要
建立并简化了燃气在室内泄漏后形成的浓度模型,分析了房间内泄漏燃气的浓度与泄漏时间、泄漏强度、换气次数和房间体积的关系。指出在燃气发生泄漏事故采取措施降低浓度时,应注意整个空间及局部区域的燃气浓度分布。
The concentration model of indoor leakage gas is established and simplified. The rela-tions of indoor leakage gas concentration to leakage time, leakage intensity, rate of ventilation and room volume are analyzed. It is pointed out that the concentration distribution of leakage gas in entire space and partial area should be paid attention when measures are adopted for gas leakage accidents to reduce the concentration.
