摘　　要：从原理和过程等多方面分析了经典二节炉法测定煤中碳氢时影响测定准确度的诸多因素,从燃烧管内的填充试剂和吸收系统药品的选择与使用、碳氢测定装置的气密性、炉温的选择等方面探讨对煤中碳氢测定准确度的影响,并提出了相应的解决方法及注意事项。This paper analyzed the impact factors on accuracy of determination of the content of carbon and hydrogen in coal using classical two-part furnace in terms of rationale and process. It discussed how these factors such as filler reagent in the combustion tube, choices and utilization of reagents of absorption system, air tightness of carbon and hydrogen testing device and choices of temperature of furnace etc. affected the accuracy of tests. The solutions and notices were proposed as well.
