本文首次比较系统地测定了10多种硫化矿石矿样预氧化前后的吸氧速度、自热特征和着火点变化情况，指出了在实验室中测定硫化矿石的自燃倾向性时应同时测定矿样预氧化后的自燃倾向性，以便使研究结果更具实用性。
This paper firstly systematically measured the oxygen uptake rate, autothermal characteristics and ignition point before and after pre-oxidation of more than 10 kinds of sulphide ores. It is pointed out that when the spontaneous combustion propensity of sulfide ores is to be determined in the laboratory, The post-oxidation propensity to burn in order to make the results more practical.
