测量不确定度在烟尘测试仪检定中的应用

测量结果不确定度的应用范围很广,从原则上说,在给出任何测量结果的同时均应该给出测量结果的不确定度。不确定度按其获得的方法分为A、B两类评定分量,若要得到某测量结果的不确定度,必须根据其仪器、设备、实验方法、人员素质、环境条件等因素提出完整的数学模型。本文依照具体情况给出本实验测量结果的不确定度。

Application of Uncertainty evaluation to Verification of Measuring Apparatus for Dust Content in Stack

The concept of uncertainty of measurement is used in many areas. On principle, the uncertainty of measurement should be evaluated when giving the result of a measurement. There are two kinds of uncertainty of measurement: Type A evaluation and Type B evaluation, which are based on different evaluating methods. To work out the uncertainty of a measurement, a whole mathematic model must be established using all of the relevant information available, which may include:equipment, experimental procedure, environment and the gernal knowledge of experimenter etc. Considering the actual condition, this article evluated the uncertainty of measurement in this experiment.
