Research on application of physical experiment data using randomicity

摘要

In order to proceed better international communications and scientific research achievements promotion, the measurement standard and its evaluation standard of commodity and technology demand sameness increasingly. But measure is always accompanied by error. How to analyse the authenticity of measuring results objectively and reasonably, the academia and technology field have made corresponding researches about this question and put forward the new concepts of measuring value uncertainty. This paper has made a detailed review on uncertainty basic theory, and combines with some typical experiments in university physics experiment, has made a practice research on how to use measurement uncertainty theory. It has made reviews on uncertainty theory; Combined with concrete experimental case, this paper has analyzed and discussed the application of uncertainty theory problem; Discussed the related problem in experimental design on using uncertainty measurement methods, and introduced how to use computer to handle uncertainty data.
