摘要
在加大氧浓度的环境中测量了三种来自不同矿区煤尘样品的化学发光.结果表明,样品组和对照组之间,以及不同样品组之间(除个别组值外),化学发光的峰值和均值都有显著或非常显著的差异.样品研磨与否和氧浓度的大小对发光有明显影响.本文对煤尘化学发光的机理进行了讨论.
3 Kinds of coal dust sample which were obtained from different region and rank were detected by chemiluminescence (CL) in the environmet of increasing oxygen. Except one group, the results showed that there are remarkable or very remarkable difference on the emission peak value and average value between groups of sample and group of control and so do groups of sample one another. The CL of coal dust samples were affected significantly by grinding on sample and density of oxygen. The mechanism of CL of coal dust was discussed.
