an apparatus for measuring explosion limit of combustible liquid vapor was designed. The explosion limits and detonation parameters, the least explosion suppressible concentration of RP-5 oil, RP-3 oil and alcohol air mixtures were measured respectively by using the apparatus and vertical detonation tube. The results indicate that the explosion limits and the least explosion suppressible concentration of the 1301 inert gas are 1.53~ 7.73% (vol.), 0.82~7.17% (vol.) and 3.38 ~18.25% (vol.) ,6.75% , 6.8% and 5.56% , respectively , for RP-5 oil , RP-3 oil and alcohol air mixtures; the least explosion suppressible concentration of N_2 , and CO_2 is 49% and 45% , respectively , for RP-3 oil air mixtures. So the suppression effect of 1301 inert gas is better than CO_2 and N_2. The critical initiation energy, detonation velocity and pressure, the width of detonation wave cells are 2.11 MJ/㎡, 1609m/s, 1480kPa, 14.5mm, respectively for alcohol-air mixture with equivalence ratio concentration.
