摘要
采用了以高一级标准物质为标准进行比较定值的方式,进而分析了火药爆热标准物质标准值的误差来源和影响因素,并评估了标准物质标准值的合成标准不确定度和扩展不确定度。
Using the primary reference material as benchmark to compare the certified the error source and effect factors of standard value of propellant explosion heat reference analyzed. The combined standard uncertainty and expanded uncertainty of standard value material are evaluated. value mode, material are of reference
