True-Twin微量热计：概念验证实验
The True-Twin microcalorimeter: a proof-of-concept experiment
摘要：
我们提出了一个概念验证实验，以实现微波初级功率标准与真双微热计。双进样线微量热仪是国家计量研究所广泛使用的微量热仪。系统校准的一个缺点是：传统过程会在系统表征和测量阶段之间改变测量条件。然而，如果馈电线是双的，则可以应用避免单独表征的测量方案，简化方程并且时间消耗减半。在这里，我们证明了这个想法的可行性。的热电功率传感器的有效效率光谱的结果进行了比较，得到的数字与公认的方法。
英文摘要：
We present a proof-of-concept experiment to realize microwave primary power standard with a true-twin microcalorimeter. Double feeding line microcalorimeters are widely used by National Metrology Institutes. A drawback concerns the system calibration: traditional processes changes measurement conditions between system characterization and the measurement stage. Nevertheless, if the feeding lines are made twin, a measurement scheme that avoids separate characterization can be applied, equations simplify and time consumption is halved. Here we demonstrates the feasibility of the idea. The result of an effective efficiency spectroscopy of a thermoelectric power sensor is compared with figures obtained with well established methods.
