摘要
根据国标附录推荐的方法,用20批煤样对制样机组进行检验,用制样机组留样和废弃样的灰分来检验缩分机;用制样机组制样和人工制样的灰分检验该两种制样方法是否有显著性差异,同时指出制样机组检验中应注意的几个问题。
According to the method that was recommended in national standards appendix, 20 batch of coal sample were used to test sample preparation units, the remaining sample and the ash of residues were used to test division machine. The ash which were detection by preparation units and manual sample preparation were used to examine significant difference, and several issues in sample preparation units detection which should be pay attention to were pointed out in the paper.
