还特地看了下维基百科Hydrogen，其中combustion里讲“……Hydrogen gas forms explosive mixtures with air if it is 4–74% concentrated and with chlorine if it is 5–95% concentrated. The mixtures spontaneously explode by spark, heat or sunlight. The hydrogen autoignition temperature, the temperature of spontaneous ignition in air, is 500 °C (932 °F).[13]……”但是也看到有人说水的存在很关键，完全没有水（分压低于某值）会在高温下也不反应。。。这，我无法解释了。感觉和混合比例（不是说达到可以爆炸的比例）和引燃条件很关键 |
