中文摘要：

基于统计分析的Logistic回归模型,应用以概率表示粉尘云最小点火能的计算方法,在容积为1.28L的Mike 3管内对不同浓度的烟酸粉尘-空气混合物进行了最小点火能测试实验,利用SPSS软件计算得到了各浓度下烟酸粉尘云点火成功概率为10%和50%时的最小点火能。结果表明,烟酸粉尘云最小点火能随浓度的增大呈现先减小后增大的趋势,最后保持在一定的能量范围内。与其他标准的计算结果相比,这种方法给出的结果更符合实际情况,也能满足不同生产环境对安全控制的需要。

英文摘要：

According to the logistic regression model based on statistical analysis, the experiments on the minimum ignition energy of different concentrations of nicotinic acid dust-air mixtures have been conducted in the Mike 3 tube by the calculation method of the minimum ignition energy of dust cloud which represented by probability,the volume of Mike 3 tube is 1.28 L. Utilizing SPSS software, the minimum ignition energy of various concentrations of nicotinic acid dust cloud when the ignition prob- abilities are 10% and 50% has been calculated. The results show that the minimum ignition energy of nicotinic acid dust cloud has a tendency to first decrease and then increase with increasing concentra- tions, finally maintain at a certain energy range. Compared with other standard calculations, the view- point of ignition as a statistical phenomenon appears to be more consistent with the test data in engi- neering, it can also meet the needs of different production environments for security control.
