针对连通容器中H2-空气预混气体爆炸建立了点火位置、初始压力和尺寸等影响因素的实验研究.结果表明,点火位置的改变对大球的影响较小,但对小球的影响非常明显.在大球和小球中,最大爆炸压力随着初始压力的增加而增加.大球点火时,小球中最大爆炸压力随管长增加的程度要比大球中大得多.小球点火时,大球中最大爆炸压力随管长的增加而增大,而小球中则先增加后减小.%A series of experiments were carried out in two linked spherical vessels to investigate the influential factors on H2-air mixtures explosion. This paper focuses on the influence of ignition position,initial pressure and pipe length on pressure in the linked vessels. The experimental results show that the variation of ignition position has little impact on the maximum hydrogen explosion pressure in the large vessel,however,the impact on the maximum hydrogen explosion pressure in the small vessel and the maximum hydrogen explosion rising rate in the linked vessels is obvious. The maximum explosion pressures in large and small vessel are both increase with the initial pressure. When the ignition in the large vessel,the change of the maximum hydrogen explosion pressure in the small vessel is more severe than that in the large vessel. When the ignition in the small vessel,the maximum hydrogen explosion pressure in the large vessel increases with pipe length. However,the maximum hydrogen ex-plosion pressure in the small vessel increases first and then decreases.
