%X 通过对贵州省内电煤在3mm粒度和1mm粒度下保留存查样的单一煤种试验,运用F检验法和t检验说明3mm粒度留样会产生较大误差;改用1mm粒度留样后检验指标合格率明显提高。 Through the sole coal experiment of the 3mm size and the 1mm size sample in the Guizhou Province electricity coal,using the F inspection method and the T-test,explains the 3mm size sample be able to have the bigger error,after changing to the 1mm size sample,the check rating qualified rate distinct enhanced
