提高煤质检测结果准确度的流程管控

Discussion on the flow path control of accuracy of coal quality test

对煤质检测中可能产生的各种误差的原因进行分析,探讨了采样、制样、化验过程中的误差控制,并提出相应有效的误差控制措施以消减系统误差及随机误差,提高煤质检测结果的准确度和可靠性。

This paper analyzed the reasons of errors generated from coal quality test,and discussed errorcontrol in processes of sampling,sample preparation and coal test,at the same time,the corresponding error control measures to eliminate the system error and random error were proposed,so the accuracy and reliability of coal quality test could beimproved.
