%X 了解煤中碳的含量,对煤的基础理论和应用研究很重要。研究开发了一个新的测量煤中碳的方法——三节炉半微量法,该方法既可以缩短试验时间,同时也能保证试验结果与国家标准GB/T476—2008《煤中碳氢的测定方法》中三节炉法所测的结果精密度无显著差异。改进后的测定方法在保证试验结果精密度的前提下,试验时间缩短约50%,提高了工作效率。 Carbon is one of the most important organic elements of coal.It is important to the theory of foundations and application research of coal,so the measurement of carbon is indispensable of coal analyse. This study is aim to find a way to measure the carbon in a short time,and the precision is equal to the three-section furnace method of standard GB/T 476—2008 Dtermination of Carbon and Hydrogen.Under the premise of ensuring the accuracy of the test results,the improved test method shortens the test time by about 50% and improves the work efficiency
