| 摘要: |
| 本文给出了采用国产稀土金属元素镱(Yb，Ytterbium)作为动态压力传感器的实验结果，实验是分别利用炸药爆炸加载装置和在本实验室的四万焦耳电炮装置上进行的。与锰铜压阻传感器、碳压阻传感器在相应装置上所得数据作了初步比较。结果表明，镱作为动态压力传感器比锰铜和碳压阻传感器灵敏度高，使用的压力范围可低至千巴 |

| Abstract: |
| The experimental results of adopting the Chinese rare-earth element Ytterbium as the dynamic pressure transducer are given in this paper. The experiment was done on an electric gun (40kJ) in our laboratory and by using the explosive loading device independently. Initial comparision has been made with those data derived from the manganin piezoresistive and carbon piezoresistive transducers in corresponding devices. The results show that as for the dynamic pressure transducer，Ytterbium has a higher sensitivity than manganin and carbon ones. The pressure range for Ytterbium transducer can be as low as kb. |
