摘　　要：通过几种统计方法的比较,选用Weibull分布来对气体传感器的试验数据进行统计分析。针对Weibull分布的参数估计并结合气体传感器试验数据的特殊性,采用威布尔概率纸法和最小二乘法对试验数据进行初步处理,之后利用极大似然估计法对分布参数进行估计。Through comparing several statistical methods and considering the parameter estimation and the testing data particularity of the gas sensor,the Weibull distribution was employed in statistical analysis of the testing data,and then the probability paper and the least squares methods were taken to process the experimental data before taking maximum likelihood estimation to evaluate the distribution parameters.
