Argon-37 is an environmental signature of an underground nuclear explosion. Producing and quantifying low-level Ar-37 standards is an important step in the development of sensitive field measurement instruments. This paper describes progress at Pacific Northwest National Laboratory in developing a process to generate and quantify low-level Ar-37 standards, which can be used to calibrate sensitive field systems at activities consistent with soil background levels. This paper presents a discussion of the measurement analysis, along with assumptions and uncertainty estimates.

微波领域的一级功率标准是使用量热技术实现的，通常与所使用的测量系统相一致，即，微量热计经过适当的系统校准后，其相对精度至少在微波域（1 GHz-18 GHz）为10^-3量级。在此，我们描述了在Istituto Nazionale di Ricerca Metrologica（意大利）实现基于间接加热热电偶的同轴功率标准的校准过程。特别注意的是专门描述用于确定微量热计的损失和它们对被测量精度的影响的接近理想的热负荷。
