用测量精度评价测量质量由来已久,但也颇有争议。由于人们对精度定义理解的不同,导致了日常使用和部分标准中表述的多样化。在放射性勘查测量应用中,也缺乏明确的定义和统一的表示方法。文章对测量精度及相关术语定义及使用进行了梳理,并列举了在有关技术规范和仪器说明书中的应用条文,总结其属于测量过程中的随机效应使测量结果不能完全重复或复现的一个测量质量评价指标,该指标不包含系统误差。最后给出了放射性勘壹测量中定点定时累积和移动定时累积两种测量方式的测量精度评价方法。
Measuring quality with a measurement of measurement quality has been a long time, but also controversial. Due to people’s different understanding of the definition of precision, it led to the diversification of expressions in daily use and some standards. There is also a lack of a clear definition and a uniform representation of radiometric survey applications. The paper sorts out the definition of measurement accuracy and related terminology and uses, and lists the application provisions in the relevant technical specifications and instrumentation, summarizes a measurement that belongs to the random effects in the measurement process so that the measurement results can not be completely repeated or reproduced Quality evaluation index, the indicator does not contain systematic errors. Finally, the measurement precision evaluation method of two kinds of measuring methods of fixed point timing accumulation and moving time accumulation in the radiosonde survey is given.
