摘要(Abstract):
经过大量的试验,并与国家标准GB/T 212-2008规定的灰分测定方法(快速灰化法)进行比对,确定改进后的灰分快速测定法的试验条件,既缩短了分析时间,又能确保灰分测定的精密度。
The improved test conditions for rapid determination of ash content in coal are confirmed after a large number of tests and the comparison with the determination method for ash content(fast-ashing method) in the national standards of GB/T 212-2008.It indicates that the improved conditions not only shorten the time for analysis and but also ensure the precision of the determination of ash content.
