摘要
用分阶段核验法对GB474—2008《煤样的制备方法》规定的粒度小于3mm的煤样制备程序精密度进行了测定,并与传统制样程序进行了比较。实验结果表明,精密度优于最佳精密度期望值并优于传统程序精密度。
Using staged checking method, the precision of preparation procedure specified by GB 475--2008 for coal sample with size of less than 3 mm was determined and compared with the traditional procedures. The test results showed the precision from this method was better than the expected value and better than that from the traditional procedures.
