| 摘 要： | 利用DAC装置及自己建立的实验方法，测量了过渡金属钨在高压（0.8~30.8 GPa）下相对电阻随压力的变化规律。在10 GPa以下的压力范围内，所测得的结果与Bridgman给出的结果符合较好。在10~30.8 GPa的压力范围内，钨的相对电阻随压力呈平滑下降的趋势。压力超过10 GPa的数据，还未见报道。

| Abstract: | The pressure dependence of relative electrical resistance of tungsten is measured in the DAC by our established method under the pressure from 0. 8GPa to 30. 8GPa. The measurement below 10GPa is in good agreement with that of Bridgman. In the pressure range from I 0 to 30. 8GPa, the relative electrical resistance of tungsten decreases smoothly with the increasing pressure. The data above 1 OGPa have not been reported to our knowledge so far. |
