煤中碳氢含量的电量-重量法和三节炉法测定方法的比较分析

Comparative Analysis of Determination of Hydrocarbon Content in Coal by the Coulometric Gravimetric Method and the Three Section Furnace Method

为进一步探究煤中碳氢含量测定时所采用方法的优劣性,选择常见的两种方法电量-重量法和三节炉法,对这两种方法可取得的准确度和精密度进行研究。研究结果显示,这两种方法在统计学上并不存在显著差异,具有相互替代的可行性。

In order to further explore the advantages and disadvantages of the methods used in the determination of hydrocarbon content in coal,two common methods,the coulometric gravimetric method and the three section furnace method,were selected to study the accuracy and precision of the two methods.The research results show that there is no significant difference in statistics between these two methods,and they have the feasibility of mutual substitution.
