摘　　要：随着科学的发展和社会的进步,人们在实践活动中对测量和检验的准确性有了更高的和不同的要求,不同准确性的测量和检验的成本是完全不同的。而在汽车排放检测领域,因其检测设备及原理的复杂性,引入测量不确定度是有必要的,可合理表征测量结果在一定置信水平下的置信范围。With the development of science and the progress of society, people have higher and different requirements on the accuracy of measurement and testing in practical activities. The cost of measuring and testing with different accuracy is completely different. In the field of automotive detection, because the complexity of test equipment and the principle, the introduction of measurement uncertainty is necessary, measurement uncertainty can represent the confidence range of mea -surement results at a certain confidence level.
