摘　　要：采用国家标准GB/T 476—2008《煤中碳和氢的测定方法》中的电量-重量法和三节炉法分别对12种标准物质煤样进行碳氢含量的测定,并对2种方法的准确度和精密度进行比较,指出从统计学方面判断电量-重量法和三节炉法可以互相替代。According to the national standard GB/T 476 - 2008 Determination of carbon and hydrogen in coal, this paper clio cartion and hydrogen analysis for 12 kinds of reference coal by both electricity quantity-gravimetric method and three-part furnace method, and compared the accuracy and precision of both methods. It was indicated from the aspects of statistics that these two methods could replace each other.

关 键 词：碳氢测定 电量重量法 三节炉法
