本文介绍了复现氩三相点所采用的装置及实验程序。设计了独特形状的样品室(温泡),使温度计浸泡在样品里。在制作恒温器时,充分考虑了消除和防止冷驻点及漏热问题。用间断加热法测得了氩的熔化曲线。温坪时间可长达两小时。目前,氩三相点的复现精度达±0.5mK。 This article describes the device and experimental procedures used to reproduce the argon triple point. A uniquely shaped sample cell (warm bulb) was designed to immerse the thermometer in the sample. In the production of the thermostat, give full consideration to the elimination and prevention of cold stagnation and leakage problems. The melting curve of argon was measured by the intermittent heating method. Wen Ping time up to two hours. At present, the reproducibility of argon triple point is ± 0.5mK.
