| 摘 要： | 文章介绍了测定钠中杂质浓度的手动阻塞计的原理、装置和实验结果。为了减少测量误差,我们研究了影响准确测定阻塞温度的因素,并且找到了减少测量误差的办法。在同样的杂质饱和温度下,该阻塞计测得的高、低阻塞温度所对应的杂质浓度差是很接近的。对氧其差值为1.03ppm;对氢为0.0763ppm。

| Abstract: | The principle, structure and experimental results of the manual plugging meterare described for measuring impurity concentration in sodium. In order to reducemeasurement error, we investigate some factors which affect accurate measurementof plugging temperature and have found the way to reduce the error. The experi-mental results show that the differences between the concentrations for the highplugging temperature and the low plugging temperature at different levels of im-purity concentrations are almost same. The difference for hydrogen is 0.0763 ppm,1.03 ppm for oxygen. |
