英文摘要： Fire and explosion caused by gasoline-air mixture in confined space usually are the most serious safety accidents in the fields of oil and gas exploitation, storage & transportation and use, petrochemical industry, city gas and municipal works, fuel strategic reserves and military oil supply engineering, etc., which often lead to massive losses. The systematic and deep experiments, including the deep experimental Research of gasoline-air mixture explosion suppression process "details", of gasoline-air mixture explosion suppression process in confined spaces for different explosion suppression medium and complex environmental conditions are carried out in this project. The theoretical analysis for the experimental results will be completed too. The suppression media involve gas, liquid and solid state ones. The complex environmental conditions refer to different initial concentration of hydrocarbon, O2, CO, CO2, solid inert particles and carbon black, different initial temperature and humidity, different explosion suppression agents' concentration and filling volume. The complex environmental conditions also include uniform and non-uniform distribution of explosion suppression agents and the changes of experimental device's scale, etc. The special explosion suppression mechanism for the different explosion suppr
