煤炭氢元素测定结果不确定度评定的探讨

Discussion on the Uncertainty Evaluation of Measurement Result of Hydrogen of Coal

测量不确定度是评定被测量的真值所处范围的一个参数,表示被测量值的分散性。用不确定度来评定试验结果,可以反映各种不同来源误差对试验结果的影响,而它们的计算又反映这些误差所服从的分布规律,对我们的试验有很大的指导意义。

Measurement uncertainty is evaluated by measuring the true value of a parameter, used to indicate the dispersion of measured values, the range of uncertainty is used to assess the test results, and can reflect the effects of various sources of error on test results, and their distribution rule of obedience and reflect the error is calculated, know about our test has a lot of sense.
