浅谈提高全水分测定的准确度

Discussion on improving the accuracy of total moisture determination in coal

分析了全水分测定易引起误差的原因,提出了一次烘样不能过多、煤样应存放于阴凉处及较湿的煤样称量前应混合均匀等相应措施,以确保全水分测定的准确度。

In this paper,the cause of error in total moisture determination was analyzed.Then the measures was proposed to ensure the accuracy of total moisture determination for example,for example,the sample shouldn＇t be over-weighted,it should be stored in shade place,and wet coal samples should be uniform mixing before being weighted.
